Jeep JKU Fender Delete to Run 37" Tires with Stock Suspension - Plus Gears, Axles and Tune

In this episode featuring the modifications on this 2013 Jeep Wrangler Unlimited Rubicon, we run through the gears and axle upgrades, tune the computer and recalibrate the speedometer, and remove the front fenders so the Jeep wont complete destroy itself on it's first trip out to the dirt.
After installing the new 37" BF Goodrich Mud Terrain KM2 tires on the JKU, I decided to get it directly to my most trusted and awesome Jeep mechanic... Ron at Blackstone Jeep Shop in Santa Clarita California for a set of 4.88 gears and chromoly axle shafts from G2. I have been going to Ron for years now and feel so lucky to have found a shop that is as honest and does such good work. If you live in the Los Angeles area and need Jeep work... call this dude 661 388 9773.
Soon as I got the Jeep home from the shop, it was time to do the PCM calibration with the Diablosport InTune module. Entering in the gear change and tire size was very easy with this tuner and I have been running the preset 87 Octane Tune for a few weeks now and like the increase in throttle response and overall performance gains on the vehicle. I do however have a problem with the fact that Jeep does not let the driver disable the ESC (electronic stability control) in 2WD and was hoping the tuner would help with that... IT DOES NOT. The only way to accomplish a defeat of the ECS is to disable all of the PCM systems including the ABS and hill assist which I don't want to lose. I then tried to reach out to Diablosport with questions about this and their customer support is pretty bad... three unanswered emails, waiting for a very long time on the phone for a tech and being told "I don't know, maybe you should look on line and buy a custom tune" is not acceptable for the price point. I do not recommend this tuner. Any help or suggestions would be greatly appreciated.
Then it was time to get ready for some off roading. I decided to pull the front fenders off so the Jeep wouldn't just rip itself to pieces on the trail. A you tuber recommended the Metalcloak Overline fenders in the last video comments and I really liked what I saw on their website so I ordered a set for the Jeep. Look for that install in a future video. After removing a few clips and a few bolts the fenders "pop" right off. I trimmed a support bracket and painted the cut.
The Jeep is as ready for it's maiden voyage off road and that will happen in the very next video so subscribe now!
Thanks for watching!

Man, I wish I had the money to just go to a shop and have my gear ratios changed to match a set of tires.
Very professional editing! Love the videos, keep it up!
I always liked the stock look with huge tires, great for lowering your CG.
looks so good with 37s and no lift! Keep the videos coming!
I gotta say, I really enjoy the high-quality, informative work you're going here. Keep it up! You're gonna grow!
+Fango925 Thanks for the nice words! Not sure about the grow thing...I've been doing this for a while now and seem to just stay right about here but I really appreciate the few folks like you that watch and take a minute to comment!
Your videos are amazing! So glad i stumbled across this channel. Keep up the awesome work
+PeteToastt Thanks Dude! I'm glad you are around and like this junk so far!!!
Great vid man... I came on board right after you installed your bumper & winch... Like everyone else, I'm impressed with your 1-man show's production value, simplicity, and adventurous spirit... ie. I don't know what's gonna happen if I through 37" meats on my stock suspension... lets' TRY IT lol... It feels way more realistic then some of the Sponsored Shop Builds that just dump $30,000 into the build and get the perfect everything all at once. I'm really digging your real-life build so far. Thanks for putting in the effort! I'm about 3 months into the journey with my 2013 JKU Rubicon... Bout to get the wheels/tires and suspension with this year's tax return. I'm looking forward to your next one.
+HDCineman Hey, it's so nice to hear about you finding this and I'm stoked you are on a similar path with your Jeep! Thanks so much for the kind words and I'm sure we'll chat at some point again!
I love these videos man. Not to many people make these jeep build videos and they are great to watch
+Brozy Hey thanks a bunch! Ok, I'll keep going...
Hi,
I really like this way of modifying your Jeep. Keeping it low and avoiding unnecessary lift is what keeps the driving experience from being ruined. We run a Tacoma on a 44" Dick Cepek tires with just over a 2" body lift. We used to run on 38" Gumbo Mudders with no lift. Albeit we had to move the control arms for the IFS down a bit in the front and completely switched out the rear suspension from a spring leaf setup to an air bag system. The rest of the clearance for the tires was made with cutting into the body. There are JK's here that are running 46" tires with no body lift but a great deal of cutting into the body and larger fender flares. One Tacoma has also no body lift but runs 44" tires with no problem. Their fender flares reach the height of the hoods in the front.
Instead of lifting it, I would seriously think about clearing out and cutting out some stuff from beneath the fender flares, especially in the rear. I would also look into trying to move the rear and front axle further apart. That gives you better suspension at speed and better angles for offroading, however the drawback is a higher risk of bottoming out on a big rock while rock crawling. Not a big issue for us in Iceland, but could be for you. If your main wheeling is done in the sand, I would recommend checking that out.
I am heading for South California in September, a big change for an arctic dweller like me and hopefully it wot be all burned down before I get there!
Keep upgrading that jeep bro, amazing video
+TheGamerBro Thanks!
Wow you are going down the exact road I'm going down. Iv got an Auto 2dJK with 4in lift. Over the last 4 weeks iv done G2 5.13s, e-lockers, bump stops, and trimmed the fenders for YEP 5 KM2 37's. On order for next weekend is C- gussets, HD ball joints, G2 inner axle shafts, nitro axle sleeves, and the km2 37s. Thanks for posting this as iv been biting my nails wondering if I have trimmed enough for the 37s. They look bad ass btw, I cant wait! I had my heart set on the bfg Krawler but apparently they stopped making them. But hell these look great!
great editing, video, and audio. learned that those clips are called tree clips too
Thanks!
Just found your channel and I like it. I just got a 2013 Jeep Wrangler Unlimited myself, so Im looking to do some upgrades myself.
Welcome and glad to hear it! Have fun!
I have a Superchips flashpaq and I am completely satisfied.
your videos are awesome. very informational and inspiring.
+Ronald Lee Thanks so much!
best videos i have seen for jeep DIY
Your jeep is going to look good with the MetalCloak fenders on! I really like how your jeep project is shaping up.
+ognaysayer Thanks dude, it makes me happy so far too!
Awesome Videos man u and fred are addicting to watch!
+Jeremy Rummel Thanks so much...glad you can share in the fun!
I live right next to blackstone jeep in Santa Clarita, that's so cool. That road you turned into was San Francisquito Cyn Road, I go there all the time to go to the shooting range
Well howdy neighbor!
Awesome vid! Are you going to put different rims on your 37’s?
Gosh that Jeep is getting better and better!!!
+quewyn That's the plan! Thanks!
love the jeep vids man
+Grant Gibson Thanks!
Subbed!! Jeeps looking awesome!!
+Fish Slayer Right on...thanks so much and welcome!
Boo Diablo. For what it's worth, I've had good experience with Superchips customer service in the past. You're an artist with those cameras, another great video!
+TrailRecon Thanks so much, just watched your Mojave video, I would really like to do that run someday! Nice work.
Thank you! The Mojave trip is one you won't regret, one of the best Jeep adventures I've had so far!
Second Superchips. I run the TrailDash 2 and love it. Very easy to use.
do u have a stock exhaust on it? and great videos keep it up and you'll be at the top in no time u earned a sub:)
Loving the videos so far....I want to dump my Cadillac and buy a jeep soon. I like the ideas you've posted so far. Could you possibly post cost of your build so far and as you go? Thanks
cool video. I'm going the opposite way first and doing the lift and then 37's
+blckrsterling I'm pretty sure that is a much better way to go about this!
awesome work
Thanks!
autoedit did you ever figure out a way to disable the stability management system like you wanted? I added a switch to my Jeep to be able to do so.
Hey just a quick question wether or not you can answer it. What iPhone holder do you have for your Jeep Wrangler? I noticed it in this video! Great video btw :)
Diablo is JUNK, I went around and around with them, and finally went with Superchips, and have been totally happy and got more than I paid for. Worth every penny, and then some.
The frustrating thing is they are all owned by holley so it's confusing how they differ.
Two video's in one week! Awww yeah
+yliaDenaLtsaF Haha! I got another one to come this week sometime of the off roading! I hope to get home from work in time to get it edited soon.
Cool videos!!
awesome video!
+TechReviewer Thanks very much!
Another Pro vid man! Teach me!
+JEEPARMY USA Thanks dude!
I really like your videos, they are very helpful as I am starting to do mods to my Jeep as well. I have a question for you about running your 37" tires. Did you feel that it was absolutely necessary to upgrade your axel shafts considering the Rubicon already comes with heavy duty Dana 44 shafts? I am purchasing the same metalcloak game changer lift as you, and can't decide if I should run 35" or 37". I already know that I will have to regear with 37" but if I had to swap out the axels too then I might just stick with 35" since axels are pretty $$. I would appreciate any advice from your experience. -Thanks
The term "heavy duty" is relative to the other components. Dana 44 axles were not designed for 37" tires and 35's will get you almost everywhere you would want to go. It's a waterfall effect on the other parts as well... axles shafts, gearing, shocks and steering components all are under way more stress with 37's and will wear out faster and cost more money. So keep all that in mind when you pick a tire size.
I personally prefer the AEV tuner for setting gearing and tire sizes. Its extremely simple. Also, not sure on newer ones like yours, but on my '08 if I hold the traction control for seven seconds, it will disable the stability control. I can do donuts and such without an issue. Oh, and just a note on doing the tire size. Measure from the ground to the center of the wheel, then multiple by two. Will make it more accurate.
+Stuka87 I tried that hold the button thing...works when in 4 wheel drive but not 2 wheel drive. It's a Jeep thing but I was really hoping the tuner would help with that. It did in my Ford.
When is the lift video? Please do one! Great videos, thank you for posting.
+Matthew Treat Lots to do...lift is on the list... stick around and we'll figure it out!
+autoedit What are your thoughts as to how high you want to lift it? I would be curious to see it with a three inch lift, but I will follow along and see what you go with!
Just got a jk unlimited for my wife for Christmas. Looking for 35 tire upgrade and a small lift. Any recommendations? Greats vids! Any new upgrade vids coming down the pipeline coming soon on your rubi?
A 2" lift and 35" tyres would most likely be a good combo. Nothing too crazy and still very usable day to day.
Hi, what size wheels are you running? Will those 37x12.50 run on a 7.5 wide wheel? Maybe fit but not air down much?
Hey do you mind if I ask about how much it cost to regear your axles, I'm trying to do that and I am looking for good prices
No guard on the grinder!!...you rebel hahah
+PHATDAN420x Yeah, not the brightest move but I just like to get working fast.
+autoedit hahaha no worries man i would of done it too
can you recalibrate the speedometer and change the gear ratio with just the tune? great videos by the way bro I love them! I'm currently saving up for 37 inch nittos and 5 inch lift lol
Yes thanks!
Put a 6" lift on that beast and you will be set👍🏻
About how much did it cost to upgrade the gears?
how much money have you invested into this Jeep to date?. I'm assuming the Jeep itself was around $40,000-$50,000
Hey man, I am looking at doing gears and going from 35’s to 37’s. How do you like the 4.88’s? I do a lot of highway due to work. You able to have good response with the pedal if you need it? What are your thoughts?
The 4.88 with 37's is as close to the original stock ratio feeling as it gets. So it's good.
I have never been a big fan of Diablo. Always ran SCT on my mustangs and love them.
+98snakehorse Cool, good to know!
How much did it cost to upgrade the gears?
Nice!!!!
Hey Jason, sweet video! What off-road park is that?
+rubioedwin80 It's a place called Drinkwater Flats North of Santa Clarita. It's a pretty cool area. The next video I'll go more in depth!
+autoedit Definitely on my list to check out. Keep up the good videos!
I kind of like the look of the Jeep without the fenders, lol. Too bad you have to put new ones on it. I've heard some of the same complaints about the Diablo tuners Jason. Did the speedometer read the right speed afterwards? Just wondering. :) ttyl -Drew
+Supradrew™ Howdy Drew! Yup the speedo seems to be right. I do like the mad max look with no fenders but the ones I ordered are pretty aggressive looking so it will be for the best! Later dude!
Awesome Jeep and great information and videos. Question, you are running 37x12.5x17 tires on a stock Rubicon rim of 7.5x17? Is it a problem running a 12.5 wide tire on a 7.5 rim? I like the stock Rubicon rims but hear the rims need to be wider to have a 12.5 tire. Please let me know what you think and have experienced. Thank you.
If you don't mind me asking about how much was it to change the gears? just looking for a ballpark figure.
+WhatTheBurdick? The gears aren't that expensive...$250 each axle but the labor to install them is costly because it takes a fair amount of time...just call your local guy and ask. I took mine to Blackstone Jeep Shop near me in Santa Clarita and they are the most honest shop I've ever dealt with.
I'm about to buy my first Wrangler (Unlimited). I'm taking all this advice to heart as far as the order that you are undertaking these mods. Would you recommend a different order in hindsight?
+Stu C Yes, for normal people I would recommend the lift first but I'm still VERY happy with the Jeep so far!
What does gas mileage look like with these tires and tune?
Nice videos.....
+oscarcortez87 Thank you!
Is running no fenders illegal in California, because in Alabama nobody does it here
I live in ca too. I'm in the process of picking flat fenders. I like the aggressive look of the narrows but I don't want to get hassled by the police. I wonder how much the care. Look forward to seeing what gender flares u chose.
+jack johnson I went with the Metalcloak Overline Fenders and am putting them on now. They are awesome but VERY aggressive looking.
Nice job!
How did you determine your tire height? I've always marked the tire with chalk and rolled one revolution then measured that distance.
+Scott Schneider That's a smart way to do it. I just put a level across the center/top of the tire and measure from the ground to that point.
+autoedit interesting. And your spedo seems to be correct?
I enjoy your videos! I realize that this video is a year old, but just in case you're not aware, there is a 'dance' that you can do to completely disable the traction control (at all times) without a programming device. Give her a google :)
Are you still running the Diablo tuner. Torn if I should just get a programmer or an actual tuner, and curious as to your thoughts?
The new Diablo is pretty good... Super Chips has a lot of good reviews.
@@AutoEdits Sounds good. Gonna try out an app called OBD JScan to as a programmer, and hold off on doing a tune for the time being. I'd be out $15 if it doesn't work basically so figured it was worth a shot.
is it possible to reinstall factory fenders after you have cut that bracket off the front? i would like to delete mine but i have to be able to put the stock ones back on just incase something happens to my jeep
I don't know. Not sure why I would want to put stock fenders back on.
hahaha awesome! when your next reddit post?
Not sure if this was mentioned yet but at 4:20 when you talk about tire size I think you may have made a mistake. Even though the tires squish down to 35.5 inches tall, they still have the circumference of a 37 inch tire. It is the circumference of the tire that is used to calculate speed and distance.
+Hobby Prepper Actually the computer specifically wants the height of the tire so it worked out perfect.
what exhaust do you have?
To turn off ESC (Electronic Stability Control) completely, hold down the second button from the left for 7 seconds. I believe it only comes back on if you turn the Jeep off or go over 40 mph.
+Ben Reattoir Thanks for the help but that only works in 4 wheel drive (high). In 2 wheel drive it just simply turns the traction control off or on and holding it doesn't do anything.
+autoedit That's odd. It seems to work in my '08 Unlimited X Sport. Also, I'm not sure if you've been on yet, but wranglerforum(dot)com is a great resource for jeep projects and advice. Everybody is really helpful on there.
a lift should have need close to the top of the list to start with i hope it at least close now
+Max23653 Yeah, I'm thinking more about it now...but there are a few other things still in line first!
whats the mpg on this beast
So how's it going 4 years later on 37's ? Still stock axels ?
I just upgraded the front but it has been great czcams.com/video/YCA-8gn5qbQ/video.html
Cant run 5:13 gears with a locker. How do i know? I stripped the teeth off of (3) sets of front ring gears. Smart call on 4:88
That's exactly what my friend told me. I've been very happy with the 4.88 so far.
autoedit
you can bulletproof the 44 or (30) all you want (synergy axle tube inserts, weld on truss, chromoly shafts, C gussets, the weak point is the .75" ring gear contact area with 5:13 gears. I stripped one set barely spinning my tires in the mud for 25 seconds.
All the money I spent I could have bought a dana 60. You did a good job on this review👍🏻
Buy an AEV programmer you will enjoy how easy it is to use
+J MONTANO Thanks for the tip, appreciated!
What did you say the width of those tires are?
12.5"
Im calling a yellow flag on the “no guard grinder” that’s a 5 yard penalty, pick up on 3rd and 5th.
HA! I have a love hate relationship with those guards...LOL
whats the biggest tire you can run before regearing?
I would re gear at 35's but that's just me.
Hey @autoedit you should add a keyword to the title, it is slightly misleading. This is a Stock Jeep Wrangler RUBICON**. The Rubicon comes with a slight lift, unlike a Stock Wrangler. Great videos anyway! Just trying to help
Drew Vance This is absolutely incorrect. All Wranglers are fitted with springs/coils that correspond to their trim package or weight. The 13th Anniversary and now Rubicon X have the most stiff coils, they also have steel bumpers and weight the most. So, yes, the Rubis do typically have stiffer coils, but no, they are not lifted...
You think with a 2 "inch suspension I can put 37 tires ... I already have high fenders ... you think I have to cut in the back ... I don't do off road
You can try it and see.
Why is it illegal to run with no fenders on? Cool Jeep, love the videos.
In certain states (like California) you must have fender flares and or mud flaps to run on public roads.
Had no idea, thanks for the answer!
Superchips trail dash 2
You should wear a full face shield when using that grinder. I wont post the pic's but they are not hard to find :-O
+ButchB1000 Roger that!
That would suck if he wasnt paying attention and buzz sawed his tire. ouch lol
Are you running wheel spacers?
Yes from G2
What size? 1.75?
is it federally illegal to drive without fenders or only state?
Theyre plastic fenders.. no one cares
if you knew you would be doing all of these mods, why start with a Rubicon? Just wondering.
Still glad I started with a Rubicon. If I eventually swap axles to 60's with air lockers that would be the deal breaker.
yea i can see that being a deal killer for sure. My buddies jeep is what convinced me to buy a sport. More than half his rubicon stuff is sitting in his garage. He even got a new transfer case.
should have got a superchips
Meanwhile my right rear fender got ripped off not by choice but because some car hit me 😔. Rip
How did you like the 4.88's with 37" from test I have seen 5.38 much better puts you at 2500 rpm at 75mph in top gear.
I think you mean 3.58? Anyway...low RPM on the highway was not the goal here. Good mechanical leverage for the engine to the wheel is what I wanted and the 4.88 with 37" tires is actually kind of close to the stock 4.10 with 32" tires. It's perfect for me...this thing would be a complete pig if it had highway gears like a 3.58.
autoedit 3.58? Where did you see that? I said 5.38:1 its the lowest ratio you can get for the Dana-44 JK some say the pinon is too weak at 5.38:1 but searched all forums and never found a failure with 5.38's. Right now I'm using running the stock 4.10's in my JKUR. find my self driving in 2nd gear a lot. Mine being an older 2007 has that low power 3.8L.
Here's why I said that... a 5.38:1 gear with a 37" tire will get you 51.17 MPH at 2500 RPM... it would take 3700 RPM to go 75.
A 3.58:1 goes 75 MPH at 2500 RPM.
autoedit Not with a 4 speed auto in 4th gear? look at this chart 70mph RPM is 2361 farm3.static.flickr.com/2447/3851963766_07f4f380cb_b.jpg
He is using a 6 speed manual.
Will a 37" tyre fit on your rear door?
They will with a aftermarket tire carrier, Teraflex sells one that installs in the stock location and beefs up the door for the extra weight.
lights and new rear bumper lol just a suggestion
+hondarider 4life YUP! for sure.
It was so easy it was supped, and to turn the ESP back on just repeat.
As most of you know, the latest
generation of the American off-roading icon, the Wrangler JK, is fitted
with a number of features that previous models haven't even heard of.
From those features, the electronic stability control system is the
most intrusive over the Wrangler's off-road capabilities, while at the
same time remaining one of its best on-road safety systems.
Fortunately, the system can be switched off for those rare hardcore
off-roading sessions, but the funny bit is that there are three ways of
disengaging it.
The first way is to simply push the ESC button on the center
console once, the second way is to push it for seven seconds or simply
engage 4lo and the third... well, let's just say that the third is for
serious professionals who know what they're doing and want the
electronic stability control system permanently off.
This is apparently called “The steering dance”:
1. Verify that the automatic transmission selector is in the “Park” position, and that a manual transmission is in neutral gear.
2. Shift the transfer case into the 4H range position and ensure parking brake is firmly set.
3. Turn the steering wheel until it is centered and the wheels are pointed straight ahead.
4. Turn
ignition on (and optionally start engine to make turning the wheel
easier - will work with or without engine running) and wait
approximately five (5) seconds for the system bulb check to complete.
5. Turn the steering wheel one-half turn to the right (clockwise).
6. Press and hold the “ESP OFF” button for 7 seconds exactly then release and wait for chime.
7. Turn the steering wheel back to centre, then continue turning the steering wheel one-half turn to the left (counter clockwise).
8. Press and hold the “ESP OFF” button for 7 seconds exactly, release and wait for chime.
9. Turn the steering wheel back to centre.
10. Press and hold the “ESP OFF” button for 7 seconds, release and wait for chime.
11. Cycle the ignition switch to the “OFF” position.
Keep in mind that the above information should be used with caution and
only before an off-road session. The electronic stability control system
does save lives on the road.

+manx1000 Hey thanks for that very in-depth how to... I tried it a bunch of times but couldn't get it right. I'm going to try another way and will shoot a video in a couple weeks.
Could I buy your old stock fenders if you still have them?
They are long gone.
I thought so, tks for replying though!
What a lovely mall crawler... nice vids man!
Hi,
In order to fully disable the annoying ESP system, you can install "ESP kill switch".
It's very easy to install, just follow this link:
www.jk-forum.com/forums/jk-write-ups-39/esp-kill-switch-writeup-260247/
I installed this switch in my 2013 JK sport, and it works really good.
In my opinion it’s a mandatory tweak for JK off-roaders.
It's really a game changer.
Superchips is better from my experience.
Love the jeep but please dont stop with the mustang
+Luke Teverino No way! The Mustang is very important to me so I'm not stopping on it. I really want to have both nice and I'm waiting for a few important pieces for the Mustang and will continue soon.
+autoedit Awesome i have a 71 mach 1 mustang and these videos have definitely
helped me restore it!
Think you should get your jeep turbo charged.. Need to help that jeeps dwindling power.
+Skoorb Brooks MMMM Boost would be good!
🇧🇷🇧🇷🇧🇷🇧🇷🇺🇸
Bathroom scale for tire weight? Wife approved! I actually suggested we use it in this video - czcams.com/video/4qThCEASfy0/video.html Great minds think alike at 9 minutes :) Awesome video and we love your Jeep dog! Checking out the next clip to see how those 37s perform off-road! Keep on Jeepin' On, my friend 👍🏼
+CRAWL TV You have a great bunch of stuff on your channel! Thanks so much for saying hey... I subscribed!
+autoedit Thanks!
Maaaaaaan, it's so wrong.
For 37 inches tires, you need to get axles 60 front and back, and get a 3.5 inches lift kit. And only than put this beautiful tires !!
Pretty soon you will break your axles, so get ready to repair them !! )))))
+x111 xxx (x111download) I'll be as ready as I can be...
+autoedit when you good to go,
good project !
Go order this lift in a 3.5in. I love mine one of the best on the market without going coil overs. www.metalcloak.com/JK-Game-Changer-Suspension-Rocksport-Edition-p/7131.htm
