Extremely thorough video. I've been doing my own research and have been building towards 37's for a while now- everything I've found in my research was covered here. Also, thanks for having a very calm demeanor- a huge change of pace for YT videos.
Appreciate the comment! 👊🏼
@@4XTRAIL I'm curious as to how much it cost to do all that work for 37" tires. Very exciting and awesome knowledge. Thanks
@@jcbert6969 Thank you for the comment! I don’t have exact numbers (I need to do a separate video where I break down cost!) but from a stock Jeep to the “weekend warrior on 37s” level plan on $10k as a middle of the road figure - definitely more if you have everything done at a shop. A lot of it depends on the brand of parts you use as well - as with most things, with Jeep parts you get what you pay for! I’ve learned that lesson the hard way! Remember too that you can stagger some of these mods vs doing them all at once. Hope that helps!
@@4XTRAIL once again, spot on. For me, I went with a ProRock44 (and everything included with that), control arms, new shocks and coils, a big brake kit, longer brake lines, driveshafts and saving for the hydro assist. Looking forward to a new video on cost estimates for sure!
@@Team_Nacho_Moto Thanks - that sounds like a great build. I think a prorock44 is the perfect long term solution for 37s. 🤙🏼
i appreciate the low tone and calm personalty. tired of getting yelled at every video
Right on 👊🏼
No shit huh nice and relaxed
Yeah why are we being screamed at in all the Jeep videos 😂
@@sdericmonty BECAUSE BIG WHEELS NEEDS BIG VOICES!!!!!
Seriously bro
Thanks
Fitting 37” tires on my jeep is my biggest accomplishment in life.
😂😂😂
yes
So I guess I would be in your weekend warrior category. My question is, if the 35's I'm running now weigh the same if not more than the 37in milestar's I plan on upgrading to, would I still have more strain. I have a 6speed with 3.73s on 3.5in. lift. I tow alot quite often, just my trailer and fourwheelers is a haul of just over 3,000lbs and the jeep does fine besides having to stay in 5th while hauling that load on the highway. Sorry for the long comment but I hope you can answer this for me.
@@lanceparrish8352 Hey Lance, I’d say if the weight is the same you won’t experience much more load on your axle and steering components. Where you’ll notice it will be with gearing because of the larger diameter. The fact that yours is a manual may help offset this a little but I would guess 37s + towing will be tough with 3:73s. The fact that the Patagonia’s are closer to 36” in actual height will help a little but you’re kind of splitting hairs at that point. I’d guess you could get away with 3:73s and a lighter 37 with manual box for daily driving but the towing aspect tells me you’ll really want something like 4:88s before too long. Hope that helps!
@@4XTRAIL thank you
PERFECT! I finally found easy to understand information I’ve been looking for. 👍
Glad to hear it! 👊🏼
Thank you sir. I'm in the process of building my jeep and researching. This helps immensely
Glad to hear! All the best with the build 👊🏼
The best video that I have ever seen .the way you explain everything 👏 thanks
Glad it was helpful! 👊🏼
That’s the most well articulated content I’ve seen on gearing up for 37”s. I appreciate the good work
Appreciate the comment! Thanks 👊🏼
EXCELLENT video - very well thought out & explained & love the thinking in threes...
Appreciate it! 💪🏼
Great video. Thank you for taking the time to share!
Glad to hear! 🤙🏼
Best video I’ve seen on jeeps explained yourself very well great job👍
Appreciate it! Thanks for the comment 👊🏼
Thank you for a very informative video, this is the best I have seen about this subject! And the best of all I know exactly which mods I need now according to my category of driving ;)
Glad to hear it! Thanks for the comment 👊🏼
Nice video. Clean clear vid.
Im just converting my Recon to 37¨s , thanks for a thorough explanation video, thumbs up !!!
Appreciate the comment! All the best with your build!
At last I can understand the
re-gearing concept! Thanks for the clear explanation!

I plan to get a Gladiator by spring, this will help me much. Thank You!
Awesome 👊🏼
EExcellent discussion. Took notes and prepared for mods,with better knowledge.tnxs bro.
Right on 👊🏼 glad to hear!
So informative! Thx! Cool looking Rig🤟🏽
Thank you! Appreciate it 👊🏼
Seriously cant believe you're sitting at 1.6k subs, This video is super helpful for new jeepers and the top comment is very true. You're straight to the point and know what you're talking about. We also have the same setup lol.
That’s awesome bro - appreciate the comment! Sharing the video always helps as well. 👊🏼
This is all sooo true. I put 37s on my JKU earlier this year and with that, has come so many more mods. All things I wish I would have known BEFORE I went there. Haha but it’s definitely a learning experience. I’ll be sharing this with everyone who asks me about my set up before they decide to go with 37s also. 😅👍🏼
Right on, Janae!
35inch and 2 1/2 inch lift for me son.
Great kick ass video!! very thorough, thanks!
👊🏼💙
Thank youuuu. Very simple to understand. great video!
Appreciate it Faith! Thanks for watching and for the comment 🙌🏼
Finally, Advices that never break the bank, Thank you for sharing some budget and we'll thought options for average Joe's like me who wants to wheel but won't spend a ton, Share more advices , it would be of good help.
Appreciate the comment! Glad it was helpful 👊🏼
Dude that was really helpful for me a new to Jeep new owner. Thanks man
Glad to hear it! 👊🏼
Yea me too thanks bro . I was thinking of going 35 but I really like the 37 . Just wasn’t sure what I needed beside just a lift kit . Great info
@@thinkclear3834 👊🏼💯
Great video man, You should do a video of how to get quality parts for cheap(without sacrificing quality) for all the upgrades here and an estimation of cost for everything separately and together. keep pumping out the great videos, you got a new subscriber here.
dirge4november84 Thanks for the kind words and that’s a great idea for a future video! I may try that.
Good content and advice. I have 35's with 3" lift. Definitely will be going 37's in the future. I just started my jeep channel and will be doing a video on what mods I have in a future video.
Right on! 👊🏼
Very informative and helpful. Thank you for sharing with us...👍
Glad to hear! Thanks for the comment
Great video. Thanks for the info.
eggmaster40 right on! 👊🏼
Well done, boxes checked and agreed with, also depending on where you live mud flaps, easily removable preferably to pop off once you hit the trail. Here In Utah they are required most places.
That’s good to know, wasn’t aware of that! Thanks for the comment.
You deserve a bigger channel man. I’m subbed now. I love the hardtop hoist video and I wanna replicate that. Great content and awesome Jeep man!

Bang up job on this video. Thanks.
Appreciate it! Thanks for watching.
Excellent video thanks for sharing! You just talked me out of 37's way too much work to run 37's I'll go with 35's.
35s are a great tire for the JK. Glad it was helpful!
3.5" backspace wheels (Method 105) run 37's like it's nothing. I had that on my JK with 17x9 wheels and 37x12.50/17. On my Gladiator, 4.5" backspace on Fuel wheels should suffice. I prefer to widen them out with wheel backspace over spacers, but that caused me to have to buy another set of wheels on my JK when moving from 35 to 37.
This video is phenomenal. I’m a commuter at the moment because of school and have 33s currently. Upgrading to 35s is hard when 37s aren’t necessarily unobtainable. Thank you for the info
Glad it was helpful! 👊🏼
33s and lockers get basically everything done
Great info. Appreciate the video.
rukenheb Glad to hear 👊🏼
Excellently explained
👊🏼💙
Excellent video!!!! Thank you
Great Video!! Weekend Warrior here minus the daily driver part. Glad to see you making the Dana30 axle work for you. Too many people hate on the Dana30 but it can handle some pretty good wheeling for the average guy. I’ll be dining the chromoly shafts soon and truss Kit.
Dirt Hammers Off-Road Thanks, agreed on the D30! 👊🏼
i just worry about the ring a pinion on my d30 especially running 5.13
If running a d30 with upgraded axle shafts and trussed, I would worry about ring a pinion. I’ve always had the mindset the weakest link should be easier to fix. Maybe run some cheap u joints. 🤔 I’d rather change a u joint or even a axle shaft, trail side then a ring and pinion.
@@300ddsrt3 definitely run cheap u joints or shafts on a Dana 30
One could convert to manual hubs and use "hub fuses".
love the video, earned a new subscriber here
Right on, thank you! 👊🏼
very informative video! well done.

Thank you for your information I’ll consider it cause I’m in Jamaica 🇯🇲
Thanks for the comment bro! 🤙🏼
@@4XTRAIL big I’m also looking for the rales on top where do I get them ?
I believe Amazon sells some inexpensive cross bars that connect to the hardtop gutter but they would just be for lighter cargo. For a rooftop tent I would recommend the rhino rack platform system! Hope that helps.
Great info. Thanks.
Awesome explanation thank you. I’m actually considering buying a lifted 2021 rubi with 37” tires. You gave me some great information to take with me on Friday to check it out
Awesome - glad to hear it! How’d it go?
@@4XTRAIL Thanks for asking, Love the jeep, test drove it with the 37's on the freeway and side roads. i was pleasantly surprised at how smooth the ride was. It has a tera flex 3 1/2" lift. I may buy it on Monday. I wanted the weekend to think it over. It has 4:10 gears in it. Whats your opinion on this size gear with 37" tires? be honest
Thanks John
With the JLs you have the 8 speed auto which really helps w/gearing. 4:10 is also the best stock ratio for larger tires. I would not be afraid to buy it knowing you can always re-gear later if you feel it needs it. Procal would still be a good idea. 3.5 Teraflex lift is nice.
@@4XTRAIL great thank you.
Great video.. right now i have 33 on my jeep .. but im planning on getting the 35 or 37 ..
Great video, super helpful and clearly communicated. You talked me out of going down the road towards 37s haha. I love the look and off-road capabilities of the 37, but not worth the extra $10k+ for those few inches to me. Appreciate it.
Glad it was helpful! Thanks for the comment. 35s are a great all around tire for the wrangler for sure! Take care.
Just got a lifted Jeep with 37s, so this helps me out a lot
Welcome to the Jeep fam!
Great breakdown list
Thanks for watching!
Very educational. Thanks
I’m glad! Thanks for watching and for the comment.
Very informative video! Thank you for listing everything out so neatly!
Quick question: How much did it run you to upgrade to the 1.25" adapters, heavy duty ball joints, re-gear, gusset kit, control arms, and break kit? Just looking for a very rough estimate... I was thinking $2-3K? I'm asking because I bought my Jeep with a 2.5" lift and 37" tires, but of course they did not add the other upgrades you mentioned in the video. I really appreciate your help!
Thanks bro! For the things you mentioned plus an axle truss (which you will also want) I’d plan around $6k. This cost would be if you got good equipment (name brand, like teraflex, nitro, etc) and installed yourself (except for regear and truss/gusset welding). If you had everything installed at a shop it’d be closer to $8k for all of those items. If you’re doing all of that I’m guessing you’re in the weekend warrior category which should also include heavy duty front track bar, tie rod and drag link (additional $1k).
I know this seems like a lot (and it is!) but depending on your driving style, how much you plan to offroad, and your stock gearing you may not need all of it. Check the video again for clarity on this stuff and if you still have questions feel free to reach out again. Take care bro!
Definitely coming back to get ideas for when i go 40s🤙🏻(in about 6 years or so haha)
Haha right on 👊🏼😂
Awesome info. Thanks
Glad it was helpful! 👊🏼
Thank you for the video! I made a list of what I need and I will order them piece by piece until I can afford the 37’s :(
Awesome! 👊🏼
Someone that finally mentions brakes on 37s. I went with Dynatrac BBK and it is a PHENOMINAL kit. For reference, the Jeep stops better on my 130lb corners now than when it did on stock BGGoodrich KM2s. No BS, it stops as well as my previous C6 Z06 did - relatively speaking here.
What is nice about Dynatrac's kit is that it's balanced to reduce nose dive. 14.25" rotors in rear and 13.5 up front. They're also American made unlike Teraflex's set. Do not go slotted or drilled rotors. Traps mud and debris too easily.
Appreciate the comment! Good insight for folks shopping BBKs. 👍🏼
I'm a year late, but great video with lots of good information. I just subbed, and I'm looking forward to watching more of your content.
Thanks for the sub and comment! Glad you’re along for the ride 🤙🏼
Sector shaft brace is a must ! Will stuffing your steering and protect your steering box
Great suggestion! I haven’t touched my steering box, I know it’s just a matter of time but so far it’s performing like a champ.
Great explanation. Thanks
Glad to hear! 👊🏼
very useful info thankz
Glad it was helpful!
Great advice, I think I’ll stick with my plan to go 2.5” and 35s on my new Rubicon based on your recommendations. Very well thought out advice based on my experience with a local 4x4 and Jeep shop
Appreciate the comment! And congrats on the new Jeep 💯👊🏼
Rubicons have Dana 45s front and rear lol you can run 37s easy lol
@@outsidewithdj Dana 45s?? Never heard of those.
@@outsidewithdj Dana 44. The outer shaft in the front axle is the same as the Dana 30 sp it's not as strong as you would think.
Very helpful video 👌🏼
Glad to hear! Thanks for the comment 👊🏼
Thank you for the video and explaining the different driving situations and what's needed for each category. I'm wanting to upgrade from 35s to 37s. I have a six in a half suspension lift and I have a lot of clearance for flexing however I just love the look with 37s and I used to have them. I swear this Jeep is making me broke lol. I would like to make it a Rubicon part by part. Thank you again.
Glad it was helpful! Thanks for the comment.
Really informative vid, I was wondering if you can do vid on 35 inch tires.... I was considering 37 inch tires, but might be too much time and money as commuter just for looks...
I ran 35s (Mickey Thompson Baja MTZ) for about 10 months and honestly that’s a great size for the Wrangler. You don’t need much other than a lift and the AEV Procal. Great choice if you are commuter and don’t want to spend money on a re-gear, etc!
Appreciate you sharing all of the information. Really helpful as I have a Rubicon 392 arriving next week and have been debating between 35" and 37" for six months! May just toss on 35" initially until I can corral all of the parts to go to 37" down the road. Thank you again for the info, much appreciated!!!
Bro - 392 cmon!!! So legit. Yeah, with that engine they may have beefed up some of the components that you need already, I have no experience with the 392s (yet!). I would guess it’s safe to still plan on everything I lay out in this vid. Congrats!
How you liking the 392 bro ?
@@pikey_life8462 Love it! Still debating 37” or 38” Now!
Great info. I would suggest the 2 in lift Mopar even for the 35's
Thanks for the comment! 👊🏼
Great video. Thanks. 👍👊
Glad to hear, thanks for the comment John!
I ran 37” bfg ko2s on my 16 JKU for 4 years and off roaded it quite often. Only front end upgrade was axle c gussets welded in and 4.56 gears front and rear. No lockers. Thing ran perfectly fine never broke a single thing in the front end other than some end link bushings and other bushings normal wear and tear.
My Jeep I installed a terra flex 3” coil lift, fox 2.0 shocks, front and rear adjustable track bars and STOCK fenders. Bump stops 2” only in the rear. Stock Willy’s wheeler wheels with 1.25” spacers.
👏🏼👏🏼👏🏼
A good comprehensive video. Just want to add you’ll need to upgrade your spare tire carrier as well.
That’s a great point! I finally upgraded mine. I ran the stock one for about 10mo with the 37 mounted on there and it kinda worked but the rear gate is much more solid with the upgrade 👌🏼
Great video man. Just got my
Jk and ordered the 4 inch lift long arm with 37s
Wizzo Musik love it man! That sounds dope.
@@4XTRAIL how common is it to snap or damage axle shafts and you didn’t mention lockers. Are they something that should come later or when you re gear
Wizzo Musik If you can do lockers at the same time as a regear it will save you labor costs in the long run. I don’t have personal experience with snapping an axle shaft but they are definitely a weak point - especially the 27 spline ones in the Dana 30. I’m still running my stock rear shafts in the 44.
@@4XTRAIL thank you , how do I know about my spline ?
Is that something that just needs to be pulled and counted manually ?
Or all jk 27 spline
Wizzo Musik It should be 27 spline for D30 and 30 spline for D44. To my knowledge all later model JKs 2012- have D44s in the rear but only the Rubi comes with D44 in the front. The sports and Sahara’s are D30 in the front. If you go to a reputable shop they should know exactly what you need.
Glad I found your channel and much like the other comments I am glad you are not yelling. LOL I have a 2016 JKU running MetalCloak 3.5 springs, Fox Adventure shocks, MetalCloak front lower control arms, Track Bar, Drag Link and Tie Rod, upgraded my ball joints to TeraFlex. I am going to be going from 35's to 37's soon. I do very light off-roading since it's my daily. Stock axle set up at the moment. I am wondering how long before I should re-gear, truss and gussett after getting the tires. Also considering the Nitto Grappler, but after hearing about the weight of the tire I am reconsidering.
Hey Jake, welcome to the channel! Sounds like you’ve done a lot of the upgrades proactively which is great 💪🏼 is your a rubicon? If so you really don’t need to truss the D44 imo for light off roading w/37s and the 4:10 gearing is probably manageable for the short term. If non-Rubi you’ll probably want to truss gusset and regear at the same time as installing 37s.
@@4XTRAIL It's a 2016 Sahara Unlimited. I was going to upgrade my tires this week, but won't be able to regear truss and gusset for about a month afterwards. The cost of the tires is emptying my Jeep budget to almost nothing.
@@A1AJake I don’t think you’ll like driving on 37s w/o regearing. There are different gear ratios from the factory but I’d guess yours are 3:21s which would be very sluggish w/37s. Using the AEV procal will help a little but if it were me I would plan on re-gearing at the same time as going to 37s 🤙🏼
Ran 37's on my 2010 4dr Rubicon.
2.5" lift
Poison Spyder high clearance flares
Poison Spyder brawler rockers
Small pinch weld trim.
Regeared to 5.13 gears.
AEV ProCal got it within 1mph of GPS.
37x12.5'-17 TRXUS MT.
handled very well on highway and the off road at Uwharrie. I didn't do the most extreme trails.
Drive it on highway from NC to MA very comfortably too.
Added note: River Raider Off Road engine to gas tank skid plate kit saves me from hang ups that the stock aid plate would cause.
Also improve aerodynamics on the road. Got the same MPG highway after the mods as it did bone stock despite weighing a good 700 pounds more.
Love it!
Great video, very informative for new jeep owner/Wheeler like me. Also your cat in the background just chilling 😂😂❤❤ so cute lol.
Nice video. Well done.
Appreciate it! Thanks for the comment 👊🏼
New subscriber. Excellent video breaking down everything needed to run 37’s on your Jeep.
I was born and raised in San Diego and used to go out off roading in the East County mountains, the desert, Arizona, Nevada, and other various location in Southern California.
When I was born, my Dad, Uncle and other family members all had full size 1/2 ton or 3/4 ton 70’s, and 80’s Chevy 4x4 trucks and we would go out everywhere in those trucks. Then as I got into high school, I bought a 1980 Datsun 4x4 in either 1990 or 1991? The truck was beat up and I bought it off of one of my youth leaders at church for only $500.00. It only had 31’s on it and maybe a 3” body lift? The truck served me well. I learned how to off road in it and babied it even though it was in rough shape when I bought it.
In 1997, I bought a brand new 1997 Toyota Tacoma 4x4 extra cab. It was just a basic 4x4 that had a 2.7 liter I4 engine and 5 speed manual transmission. I went everywhere in that truck and set it up for off roading. One of my biggest regrets was getting rid of that truck though.
After I got married, my wife, kids and I moved to Colorado, where she is from. In 2007, I bought another Tacoma. This time around, I got one that was a little bit nicer. It was a 2007 Toyota Tacoma extra cab TRD Off Road. It had a 4.0 V6, 6 speed manual transmission and a rear locking differential. I really loved that truck too and it off roaded even better than my original Tacoma, because it had a locking rear differential, a leveling kit and bigger tires. Going off of memory, I think I was running 33’s on it? The only reason why I got rid of it was because our kids had all outgrown the extra cab back seats. Since trading it in I have owned full size 1/2 ton 4x4 Z71 Chevy trucks but I am now getting ready to buy another vehicle for off road purposes only or predominantly at best, since I will be keeping my full size truck as well.
I have my choices narrowed down to either a brand new 2021 Toyota Tacoma TRD Off Road Pro, or a 2021 Jeep Rubicon 4 door. My heart wants another Tacoma but for what I am wanting to do, I know that a Jeep Rubicon will serve me better. Not only does it have a rear locker like the Tacoma TRD Off Road and TRD Off Road Pro does, but it has a front locker as well. And a sway bar disconnect, and is easier to lift and put bigger tires on it.
I’m leaning towards the Rubicon and if I do end up choosing to go that route, it will be neat to see how well they off road compared to the Tacoma’s. I know that they will do much better but am not sure how much better?
Hey JR, awesome story! I had a 3rd gen Tacoma TRD Off-road before the Jeep. I didn’t wheel it very much but I can honestly say that for me, the Jeep is much more fun to drive. My wife drives a 4Runner so we are still a partial Toyota fam 😉. In my opinion you can’t go wrong either way but I think you’ll enjoy the Jeep more. Would love to hear what you decide!
Great video. You just talked me out of getting 37's.
Glad it was helpful! 35s are a great option!
Thanks for sharing your video I’m new on the Jeep world and there’s is too many different info that. Can make people confused. I own a 2017 jk rubicon. Very happy till star changing stuff. Front edge fab four. Fab Four fender flare. That seat to high making the title run very small I hate it. Currently on 35 12.50.20. So I’m looking to upgrade my tires to 37 and here we go really don’t know where to star. I have a appointment. To do re gear and alpine arm control So they guy told me that all I need since i don’t do any heavy hardcode of road mostly driven to work and back Since it’s a rubicon. He said I be fine. Now today another Sales rep came he said you should do a trust and chance all you axel
All of this

Is this all this necessary since this wil be on the pavement. Maybe lake real light of road
Thanks on advanced
Hey - I’m not sure I understand all that you are asking exactly but I would follow what I lay out in this video for “commuter” category. Rubicon should have 4:10 which may work for 37s on pavement - worth trying if you already have the lift and geometry right. You’ll want to upgrade gearing eventually and when you’re having that done you should consider ball joints, c gussets and axle truss at the same time because it’s all in the same area of the Jeep so you’ll save on labor costs. The IR arms are great and I definitely recommend for larger lift/tires.
I run 3.5" suspension, 1.25" body oem rubicon wheels , 1.75 spidertrax spacers. 4.10 gears with tremec 5 speed trans . Big brake kit, psc titan xd box, minor trimming, drag link flip. Stock shafts and drive shafts with a terra high angle cv. Stock steering tie rod and rod end are all strong, moog oem replacements are greasable. Stock ball joints went a long time, but terras are coming soon. Dana 30 housings are the same tubes as a Rubicon d44.
Sounds like a good build Charles! Thanks for watching and sharing.
Just an FYI,, on JK's the max tow package is how you get 3.73's on non-Willys edition Jeeps. Either way, they need to go. Also, I only run 35's and went with 4.88's. I came from the smallest possible stock tires and it returned it back to that feel.
I appreciated your approach as others have said. My only suggestion would be some B roll of your axles and drive shafts.
Great insights! Thanks for sharing.
I dont think there's a better way to explain any of this! Excellent job sir! Im running 37 inch trail grapplers on dv8 beadlocks on a teraflex 2.5 inch lift. I've ran that set up for about 30k miles with some good wheeling. I do get rub on the frame rails at full tuck and full lock but not enough to worry about damaging anything. The one thing I'd recommend to people is to run 4:88 gears with an auto trans and 5:13 with a manual, if you wheel anything fairly difficult. Im running 5:13's with the 6-spd manual. Anyways. Great breakdown video!
Great input on the manual vs auto. Thanks for the comment! 👊🏼💯
@@4XTRAIL if you ever find yourself in Michigan id highly recommend going up to drummond island! Great moderate to semi difficult trails and some pretty amazing scenery!

Nice! That’s going to be one tough looking TJ 💯👏🏼
Hi. Great video! Highly appreciated 🙏🏼. I’m new in the Jeep world. I just bought a 2020 Gladiator Rubicon Launch Edition and I consider my self a weekend warrior. I listened to your video very carefully and the summery that I got is as below. I would really appreciate it if you would go over my summery and check that I have got everything noted also to advice if it’s needed for the car I have or it already has things from the factory that will do the job being a 2020 gladiator rubicon launch edition. As some things are new to me the spelling is also wrong so I would appreciate it if you give me the correct spelling so I would start doing my research and budgeting. Here is the summery:
3.5 lift kit
37 inch Tiers (make sure they are 37’s on 35’s branded as 37’s)
17 inch wheels with beadlocks
4.75inch back space
-6mm off set
1.25inch teraflex wheel adaptor ( or similar solid quality)
Heavy duty ball joints (teraflex)
C gusets (guset kit)
Axcel trus (not tube sleeves, not as huge as a prorock 44 or 60)
Axcel shafts Ten factory cromaly 27 spline
Drive shafts Adams extream duty front and rear
Upgrade draglink
Upgrade tierod
Upgrade front track bar
Hydro steering
AEV pro cal
Regear the gear ratio to (4:88)
Control arms
Bigger brakes kit (front only no need back)
Once again thank you in advance.
Best regards,
and all the best 🤙🏼

Hey man! My apologies, somehow I missed this comment until now. I don’t think you’ll need to do everything on this list, at least not right away. Here are some things to consider based on the fact that you have a gladiator rubicon: you may be able to fit 37s with only 2.5” lift. Control arms would still be a good idea but with only 2.5” lift you might not have to do all 8 arms. You would need to research a little more on your own to determine this (or call a reputable offroad shop in your area and ask). You also should be fine running your stock axle since the rubicon’s come with a D44 front and rear. C gussets and axle shafts would still be a good idea at some point but probably not necessary right away (the D44 have 30 spline axle shafts not 27 FYI). I don’t think you will need hydro. You should try the stock gearing before paying for a re-gear. The JL platform uses the new 8 speed auto transmission + the rubicon should have 4:10 gear from the factory. That combo isn’t too bad! Finally, I think I misspoke on my wheel backspacing and offset. You should try a wheel with 3.5” backspace and that should allow you to not run any spacers/adapters (again, worth double checking this for your application to make sure). Hope that helps!
Really great video! Thanks for breaking it down, made it much easier to understand.
Do you have any tips for someone new to Jeep Wranglers wanting to learn the mechanics behind it all? I absolutely know nothing about how vehicles function expect for you put gas in it and a battery and it runs. 😅 lol. But I would really like to get to a point where I can upgrade my Jeep in my own garage (lift kit and such) and know how to plan my mods better, and also to know how to repair it if problems occur out on a trail. Where do I start?
Thanks, I’m glad you enjoyed the video! These are great questions. First of all, the cool thing about Jeeps is YOU CAN work on them yourself. They are great for learning how to work on your own vehicle because of their simplicity.
Here are a few thoughts about working on your own vehicle:
1. Safety! Make sure you watch some videos or preferably talk to a trusted mechanic about the proper way to jack up a vehicle and other safety measures before you get underneath your Jeep. This is simple but if you’ve never worked on a vehicle before it’s really important to understand.
2. Watch some basic videos on how cars work. The Engineering Explained comes to mind but there are many great videos out there that will help you gain understanding about the basic components and how they function. Even if it’s not specifically a Jeep video you’ll be learning basics that apply.
3. Tools! You don’t need anything crazy to work on Jeeps but a solid “mechanics tool set” from someplace like HomeDepot is a must and will serve you well. Try to get one with a lifetime warranty (most good sets have this). Also a large floor jack and 4 heavy duty jack stands. Other tools can be added as you go along like an electric impact driver, torque wrench, etc. the list gets long quickly!
4. Jeep specific videos. There are some pretty solid channels out there with content that will really help you. For installs I tend to like stuff from Extreme Terrain. Install videos are a great way to learn. If you have the right tools, an attention to detail and a good CZcams video you can do a lot!
Hope this helps! Also check out TrailRecon for general Jeep inspo. Brad is awesome and has the best Jeep videos on CZcams IMO including some great “what tools/gear to carry on the trail” videos.
@@4XTRAIL Thanks for the reply! I couldn't agree more, I, as well, enjoy watching TrailRecon.
Thanks for the info! Really helps me out. Can't wait to get out on a trail for the first time.
I need this type of info for my 2018 Rubicon JL which is higher than a JK( I had a JK too). Good video.
Appreciate the comment bro! I know Brad of Trail Recon just dropped a great video comparing top suspension lifts for the JL. Not quite the same but might have some helpful info 🤷🏼♂️
Well done!
Thanks for the comment!
I am so glad I ran across your channel while looking for advice on what it takes to run 37s! I am also putting the Milestar Patagonia MT on my JKU, and wondered what tire pressure you found to be best? Of course I'll do the chalk test, but was hoping to be close to start. Thanks for all the information, much appreciated!!!
Hey Scott! So glad to hear the video was helpful for you. I found out that Milestar recommends 36-38psi for their Patagonia MT in a 37”. This is higher than most 37s due to the Milestars being a domed design vs flat / squared. Because they are domed you can’t really do the traditional chalk test. I ran mine around 33psi to get them to have a softer on road ride but they wore uneven and got really noisy by about 20k miles. Here’s some more of my thoughts on these tires: czcams.com/video/vHxZ777REIk/video.html take care!
@@4XTRAIL thanks again!
@@4XTRAIL I watched the video for the 25k review which clarified the tire pressure, but I was curious what you run when offroad, especially rock crawling?
@@sagoodman988 I typically run 15psi offroad and around 14psi or a little lower for crawling. Non-beadlock wheels so I try to stay around there.
@@4XTRAIL great! Thanks again!
Re-gearing is highly recommended when going up in tire size and wheeling. 4.88 or 5.18 Yukon.
Yep. I think you mean 5:13s? Been happy w/4:88s and 37s. Went with 5:38s for my JT on 40s but it’s still in the shop so tbd on that combo…
All you really NEED for 37s on a JK/JL Rubicon is the right wheels and tubed fenders and/or a 1" poly bodylift. It helps if they're narrower than the typical 12.5" width.
Adjust the steering stops if necessary.
35s can similarly fit a TJ Rubicon with stock springs. JP Mag did an article on it many years ago. A TJ would want for adjustable rear control arms too. Stretch the wheelbase a hair.
High clearance. Low COG. Especially if you also use high-clearance skids.
Hey! While it’s true you can fit 37s on a Jeep without doing much - the point of this video is what you need to do it sustainably without breaking things over the long run (or lowering your chance of premature wear / breakage). Thanks for the comment and info on TJ! 👊🏼
Can you do a video on list for 35s would help a lot of us out to understand what we really need.
Hey, thanks for the comment. I may add that to my future video list!
Thank you ! I am gonna show my wife this ! She has a stock 16 willys 2 door! And desperately want the biggest lift and tire available ! If I can only get her to pay attention to hear all the work involved !
Glad it was helpful! 👊🏼
Love your content man, straight and to the point!
So not sure if you’ve had experience with the JLs or know too much about them but I have a JLU Sport S V6 auto with the LSD D44 rear but a D30 in the front. I’ve been running 37x12.5x17 Toyo MT with KMC wheels non beadlock for almost a year now and have used it more for overlanding, Forest Roads to camping spots, and occasional moderate blue trails like Broken Arrow in Sedona, Arizona (handled like a champ, didnt struggle at all). So I would place myself in the weekend warrior bracket. But I’ve yet to do any upgrades to the D30, eventually I’d wanna do a PR44 but just isn’t in the cards right now to drop $4k-$5k.
Would just having C gussets, truss and regear to 4.88 suffice for what I use it for? Have a local shop that quoted me $2100 OTD that’s installed. Which in my opinion is a great price. I’m not hard on the pedal on the trails and don’t wheel places where lockers are needed or anything above a blue rated trail. Basically just working with what I have for the moment until funds come available for a Dynatrak PR44 in a year or so. Sorry for the long comment hope anyone can chime in to tell me their experiences or advice! Happy Jeepin 🤘
Hey bro! Thank you for the comment! Yes, exactly. The re-gear, truss and gussets (and ball joints) should get you through for a while based on the type of wheeling you described! I hope to make it out to some AZ trails soon - looks absolutely beautiful! Take care 👊🏼
Tj 4 banger 37 13.5 17 super swamper 1 .25 spacer 4.5 lift, 513 's,adj control arms thats it runs great
Great video for useful info. I have a 07’ JK 2 door, auto with 3-4” lift. I’m running 35’s right now, but may look into 37’s when it’s time to replace. I have a Skyjacker Hydro7000 lift, would that be hydro steering that you spoke about? It handles exceptionally well, and has no body lean at all. The handling is great. Your thoughts would be appreciated!
Also, I like your front bumper and wheels, what are the brand & specs on those? Thanks again!
Hey! I love 2 door Jeeps, that’s awesome. I’m not familiar with the skyjacker hydro7000 lift but that is different than the hydro steering I referenced. Hydro ram assist steering is a steering ram piston that mounts to your front axle and assists the steering box in turning the tires.
If your jeep handles great I would try to stick with as much as you can! Going from 35s to 37s may require a re-gear depending on how you drive and the gear ratio your jeep has currently. Acceleration and general performance will decrease the larger tire you run unless you offset the hearing accordingly.
The front bumper and wheels in this video are: rugged ridge HD stubby bumper and ProComp Series 69 17x9 wheel.
Hi, I have 35 on my JK, for the breaks I highly recommend Teraflex big disk kit. It works perfect with the OEM calipers. Since the JK have so small rear disk y better if you do both at the same time. You can work with them if in the future you want to move to the BBK. The only regret i have is not doing it before.
Great comment, thanks!
If you're using 15" rims, an upgrade to stainless hoses and premium pads may be all that you can easily/inexpensively do. Larger rotors would put the calipers too far out to clear 15s.
Just saw this video and it looks very informational. Don’t think I have the budget to run 37’s. Can you make a video on the list of items needed to run 35’s? Hoping to start out with a smaller budget but still relatively more capable than stock
35s are a fantastic choice for the JKU. If you have a Rubicon with the D44 front axle and 4:10 gearing there is very little you need to run 35s in my opinion - unless you are wanting to do consistent, hardcore wheeling. If you’re more of a weekend warrior you will want at least a 2.5” lift, an AEV procal or equivalent to program your shift points and odometer, HD ball joints and 1 ton steering. I would call this a “stage 1” for running 35s. I ran 35s for a while without much more than a lift but I would recommend the above for sustainability. I need to do a video at some point where I lay out more details on this! Hopefully that will get you started. There are plenty of forums out there with this topic as well.
Excellent video. Informative and interesting; but you can also buy a JT Mojave or a Wrangler 392 and fit 37s effortlessly
I know this is an old video. What you need to run 37s depends a lot on your model. JKs, even Rubicons, require a bit more to get there than JLs. A JLR can be put on a 2" puck spacer lift kit and then you're pretty much set, assuming you have a wheel with the proper offset. You'd probably want to regear but you could run it. Anything other than a Rubicon would require high clearance fender flares in addition to the lift, plus reinforced axle shafts in the front (rear, too, if you don't have the rear Dana 44) and preferably some HD ball joints plus some better breaks. Plus a tailgate reinforcement kit and spare tire relocation bracket.
Great Video, appreciate you got into the deeper portions of reality in this video. Super helpful for those of us mechanically knowledgeable but not well versed in JK Wranglers specifically. Thank you
Glad to hear, thanks Levi!
This was a great vid!!!! It would help a great deal if u shared links to everything
Thanks for the comment! Glad you found the video helpful. I agree, in the future I may try linking a .doc to the video description. Thanks!
FYI not all rubicon models have 4:10 gear ratio. Both my 14 and my wife’s 17 have 3:73 gear ratio stock. If the tow package was ordered from the factory with an automatic transmission then you would get the 4:10 gear ratio. The other way it would come factory in the Rubicon is if it were a manual transmission. I went with 5:13s in my 14 JKUR. The end goal is not to be a daily driver when my daughter graduates and goes to college. Good information and solid advice. Maybe next video is upgrading to anti rock system and ditching the electronic sway bar disconnect junk the stock Rubicon comes with.
Thanks for the clarification! Right on.
Great video! Thanks for making it so informative. I am planning to install 37s on my Jeep Wrangler Sport for aesthetics and don't plan to take it off-roading. I'm assuming I would not need a lift kit, but please correct me if I am wrong.
Hey Robin, good question. I don’t think you can physically fit 37s on a JK without a lift. The minimum lift height I’d recommend to run 37s is 2.5” with flat fenders. That plus a wide enough wheel offset should allow you to drive around on the road just fine. Hope that helps!
@@4XTRAIL thanks buddy!
Another point to remember is tire weight. The Patagonia MT’s 37 and 38 inch tires are actually lighter than most other 35 inch tire brands and half the weight of most other 37 or 38’s so they don’t put as much stress on the components so it’s good practice to compare weight when selecting which tire you’ll be running. We have the exact same Jeep. I have a black 2016 jku with 38 inch Patagonias. I bought a buddy of mines front and rear rubicon axle set out of his rubicon and trussed both front and rear with 4.88’s and OX cable lockers front and rear with a six speed manual with the 4 to 1 transfer case. You can walk faster than it will crawl. Our jeeps actually look identical.
That’s a great point that can’t be emphasized enough. Weight matters! Sounds like you’ve got a great build going!
