- You guys have been asking for a while, so we finally did it. All the benefits drawbacks of going to 37's along with all the trimming that has to happen on stock fenders.
Check out Part 2 of this video series as We test the 37's of-froad:

Love your involvement with your boys helping out.
its probably hard to do it while in the wheel well but holding the hammer farther down the handle helps, after working on truck brakes I never want to work inside a car/light truck wheel well ever again
Andy Brooks we tried that, there is a whole twist your body type of technique that I saw the guys at RPG do. We did not have the strength or the skills to do it.
So many questions answered.
Thank you Helio!
Daniel Miranda your welcome. Still a lot more to come on this topic as we go test it out. Fingers crossed we don’t rip off a fender
Thank you again for another extremely detailed how to video brother. It helped me out tremendously!
Thanks man.
Make sure you watch all the videos in this playlist. We tested the typical trimming everyone says is all that’s needed and found that more was needed. We show our testing and everything too to back it up
The bigger tires do look better, but I don't like the extra weight or less power. I'm keeping my truck the way it is. Thanks for this informative video, you do a great job doing interesting topics that keep the subscribers coming back. 🖒
Erik Racz thanks man 🙏🙏
I was in the same boat, the power and performance of this truck with 35s is awesome. 37s are more of a headache than they are worth. But they kept giving me 37s and I can’t let them go to waste
Big cojones to take on that project; awesome job by you and the boys!
Thanks man. Make sure you check out the series. We did a lot of testing and additional trimming to dispel a lot of the myths and bad info from the forums
Excellent, lucid and well produced videos! I have learned a lot from you. I'm going to keep my 2011 stock with the 35's but I do like the look of the 37s for sure. Just replaced the rear leaking Fox shocks with new ones and now going after the front shocks, your video helped me tremendously. Happy miles!
Thanks man. This is why we created the channel. We got a lot of bad advice when we started and we’ve learned a lot of lessons the hard way.
with ur shocks did u do something to them with the perch or u just left it standard because mines was standard and then i went to mid perch and i should have went to high fareal
Gen2 don’t have a mid perch option.
We did Eibach springs to get a little more height up front.
@@KeepItDirtyOffRoad o ok i have the gen 11 ok i didnt know that about the other gens
At 14:19 on the right hand side you can see the A/C drain coming out of the cab. They will almost always have air blow the water back inside and ruin your carpet. I used a 90° pcv hose to fix it. No more wet carpet.
Raptor.Tremor never had problems with wet or musky smelling carpet. Are others actually having this problem? 2 Raptors now and never had this issue
@@KeepItDirtyOffRoad I have the issue on my tremor and expedition. Dealer replaced while carpet. There are gen 2s that have the issue. I think it goes back to 2004 ford trucks
Awesome video!! now I need to this to mine
Let us know how it goes. Also watch out for our update
Very nice and informative video! I'd recommend you get some jack stands because I've seen hydraulic jacks fail all the time. Keep it dirty and safe off-road. You've got me subbed!
Dr. Konfusir thanks man.
if you look closely we always either put the weight on a jack stand, or set one up for safety.
Great info. Looking forward to the offroad video with this setup. When you say you’re going to be doing a suspension upgrade to handle the 37s, are you referring to 3.0s? If so, which one are you going with and why?
It's your truck you can absolutely do as you wish. My impression of the truck, I have a 2019 Raptor, is its dialed in perfect to me with the 35s. It seems like the mods you have done could have caused you some of the issues you have had.
Great videos, great to see the boys involved in your passion. Thanks for passing it on.
Thanks man. I’m in agreement with you and mentioned it several times over my videos. Only reason I did this video series is for 2 reasons. 1. Too much bad info online on 37s and the Gen2. There are way too many posers and pavement princesses that say it works with light trimming. In the next video I proved it wrong. And showed what it’s actually required just to clear them.
2. I was given 2 free sets of 37s. It was either sell them or use them. I picked the let’s prove some of the myths wrong route. A route I’m really not liking. 37s limit the truck and cause so much more wear with a stock ish setup.
@@KeepItDirtyOffRoad I am glad you didn't take it wrong. You use your truck. And teaching your kids is great. They obviously highly respect you. Keep up the good work and thanks for some great videos and information.
Great video. One thing to note however is that 37s don't always weight more. For example the Factory Beadlock wheels and stock KO2 tires are 107 lbs, the non-bead lock wheels and factory KO2 tires are 100lbs. Most of the aftermarket wheels weight less. So for example my Fifteen52 traverse HD wheels are 29.88 lbs and 37" KO2 are 69 lbs for a total of 99lbs. The 37" KM3 are 77 lbs so with my wheels its a total of 107 lbs. They do change the gearing slight due to the increase in overall diameter.
Kristopher Derentz they don’t weight the same, but it’s night and day difference. There is a clear difference in performance and response.
tthat is so true
Great video and informative on pros and cons on fitting 37s. Maybe look into regearing to 4.56 gears from the stock 4.10s to bring the powerband back to stock and get rid of the sluggish heavier feel with the bigger tires. I have the Cobb accesport with tcm and so far I like it. It gave noticeable power and made driving in sport mode enjoyable and got rid of the clunky oem shifting in that mode. Here in the southwest where I live we only have 91 octane so I can only use the 91 octane program but I believe in California you have 93 octane readily available to use the 93 octane program for bigger gains. I also think you had a programmer on the previous truck but removed it cause it gave you codes or problems not sure. Well anyway, great video and looking forward to possible front suspension upgrades
Marco Perez 93 is hard to find in Cali. Texas is where it’s easy to get.
I did run the Cobb tune in the last truck with 37s and I did not like it. Back then there was no transmission tuning and I had to reset ECU almost weekly to get the truck from shifting all hard. The tune also did not really help on the top end. It felt like once you hit 75-80 she had nothing more to give with 37s. Trying to get over 90 on dirt was just not possible and signs of an incomplete tune because she kept overboosting too. It a fan of the Cobb tune.
😳😳😳😳
Yeah .... Think I'll stick to 35's
Strong work guys 👍🏾
Mo_ Muscle351 don’t blame you. I struggled for a long time on the switch. I even resisted it on the new truck. But when you have a garage full of 37s, I can’t just let them go to waste
@@KeepItDirtyOffRoad completely understand and you also have helpers 👍🏾
Mo_ Muscle351 oh yeah. I could not do it without them.
Have you looked into re-gearing, might be worth a look. Great videos!
R Thompson check out the latest video. It is something we are looking at
loved video, but just bought a 18 leadfoot gray raptor. love it as is. i will not ever need 37s but really enjoyed your video. i am an xvette guy that wanted a sharp trk with power, the 18 raptor is that.
Thanks man. 18 is probably the best choice for the Raptors. It’s the year with the least issues and most improvements
Well done, I did the same thing on my 2017 back in January, I put a few coats of flex seal on the bent pinch welds instead of paint( and wish I had started with caulk in the cut lines first) to help reseal up the outside elements from entering into the cab.
And yes a long handle 12lb sledge along with an short handles 8lb did the trick for me, but still took a sh*t ton of beating to get them flat. The second side took half the amount of time though after I learned how to do the first side, lol.
Great video!!!
Thanks man. Yeah shit ton of work. Made harder by not being able to get a 12lbs hammer
That stuff smell great!😂😂😂
Yeah I think I’m gonna stick with 35s sounds like a no brainer to me
H/C 707 🤣 I completely understand. I wanted to stay with 35s on the new truck. But they kept giving me 37s and I can’t let them go to waste.
I've had to trim alot for my buddies raptor to fit my old toyos off my dodge. The 14" wide MT dosen't look big on my 2500. But it looked monstrous on the raptor. But a solid deal is a deal. Ive had to trim to run 0 offset on the solid axle dodge platform. I just beat my pinch weld flat and called it a day.
Did you do any fenders too?
Yeah, he's running fiberwrex. Not the best quality but he got them cheap.
Dude you're son is super cool. Keeps me laughing lol
Great video! I think it has convinced me to stick to 35s though... I bet a 3X pneumatic rivet gun would do a beautiful job on those pinch welds
John Morrison to cut them or bend them?
To hammer them... They’re hard hammering SOBs designed for use in tight spaces. I think you’d be able to get those seams nice and flat and you would run zero risk of whacking something you didn’t mean to.
Bent mine with vise grips first then kept triggering the fuel pump cut-off switch with the sledge hammer. The switch was right behind where I was hitting on the passenger side. I have a 2001 F150 with HM suspension front and rear and of course my pinch weld seams were steel.
Yeah, does not matter if they are the steel or aluminum, Ford made them super strong
@@KeepItDirtyOffRoad Yep, I only had a short handled 5 pound sledge, but swore I was going to break something I was hitting it so hard.
Nice video on the job and you do your best with what tools you have. If I could only give you my heavy duty adjustable wrench it would be the perfect tool to get the over lapped metal started to 45 degree bend into the frame and then use the hammer to send it home 90 degree. I think I will stick to 35s on my raptor. I suppose you could add the bigger inter cooler to get you back to stock power? Love this content 👍
Paul Newman thanks man. We tried a wrench and there is not enough space and the welds are super strong. The only way to bend is brute force.
I was the same thinking. I wanted to stick to 35s. But I had a garage full of 37s. 2 sets actually. I could not let them go to waste and no one wanted to pay what they are worth. So 37s on the truck.
I have a video coming up on the rubbing and that’s going to change a lot of minds on 37s . Stay tuned for that one
Hello , I own a 2017 Raptor .Do you think the Fabtech Suspension Lift System 4" is a good choice to put a 37 tires . Thank you so much for your videos
A “lift kit” is the worst thing you can do to a Raptor. Specially if you want to put 37s on the truck. For one, the lift kit removes any off-road capabilities of the truck. The shock spacers they use will collapse first wash or small jump you take at speed. It also changes the suspension geometry such that it eliminates most of your suspension travel. And finally, you still have to trim because the tires will rub a lot.
Don’t put a lift kit on a Raptor.
Great video,, what are your thoughts on 37 13.50 General grabbers on a -44mm offset wheels, with the 3.0 kings and icons leaf springs, do you thank am expecting more or less trimming ,, thanks.
Your ripping fenders off.
Sorry. But have to be honest man. Stock wheels are at 38 offset. The max most run with 12.5 is 0 offset. And they still touching but not rip fenders off, just touching.
I ran 0 offset with 13.5 Nitto terra grapplers and basically came up right to the range of the stock fender. Popped off the fender trim a few times in o shit moments.
With any form of negative offset your ripping off stock fenders and most aftermarket fenders too. Specially with -44mm. That’s almost 1.75 inches wider. If the tires go full tuck that’s ripping the fenders off and causing some damage.
Why size wheels would you recommend for the 37s General grabber x3!
+6 to 0 offset. Most will run 0. But with a 13.5 in wide tire a +6 may be needed.
If your off-roading look into Icon or Method bead grip wheels for affordable and strong options.
Great, thank you.
How much cutting do you think would be needed for street use? Sadly not many trails are wide enough in TN for the raptor.
Blake Smith i would recommend what we show in the video as the bare minimum for street use. We fully expect to do more trimming as we start to play more offroad
Keep It Dirty Off-Road thanks! Love watching all the videos you all make. Makes me envious of the trails there!
Blake Smith thanks man. We are kind of spoiled down here. You have to make the trek out sometime and see what your truck can really do.
Are you re geared for the 37s? Or is that kinda overkill? I feel it could help the fuel econ
It can help and I was in the process of doing it. BUt, my truck started having some major problems and all upgrades were stopped.
I wonder if using two 12" adjustable wrenches tightened down at the edges of the bend and inserting a steel rod through the holes at the end of the wrenches then pushing on the rod would have made it easier to bend those pinch welds.
Maybe, maybe not but leverage is your friend.
Seems like there would be enough room and the distance in between the cuts is small so even though the wrenches wouldn't be exactly parallel to each other a smaller rod should still fit through both holes and what's important is the distance that is now much greater away from the bend giving you extreme leverage.
Many times at work we come across obstacles we simply couldn't do unless we figure out a way to utilize leverage and then the impossible task becomes real easy.
Great video.
Not enough space for leverage unfortunately and as the pinch welds bend they go flat on the body. This is one of those rare cases where brute force is the only effective option
@@KeepItDirtyOffRoad
I figured that room might be an issue however this would be used only to initiate the bend to a point where a hammer could then finish the job.
sixshooter4570 we did try it on the driver side with some players, but even with all my 210 pounds on it, there was no budging. Those pinch welds are thick and take a great deal of force to bend.
Thoughts on a throttle commander rather than a tune? The truck doesn’t spend much time off-road
I’m personally not a fan. The throttle position foolers tend to cause these trucks to go into limp mode. Seen it happen a few times with the Gen2 platform. Some guys run it and never have a problem. Others can’t stop having problem. It’s hit or miss so I’m not a fan.
15:33 😂 bigger hammer helio
🤣🤣 yep. We needed it.
Hey will you guys be updating your Amazon store link? Just curious what impact wrench you use.
John Gordon we always keep the amazon page up to date. We get most of our tools from Harbor Freight. So if it’s not on our amazon page, check HB and you will find it.
Will a 2014 ford raptor rims with negative 34 and 37 tires fit the gen 2 raptor?
Stock wheels are only positive offset last time I checked. +34 so more inboard and the same offset as the gen2 stock wheels.
Trimming will still be required.
Widest I’ve seen is -12 and those will just rip stock fenders off and not recommended as there is no trimming that will avoid contact . 0 offset is the standard for raptors.
@@KeepItDirtyOffRoad nice thank you I will try it
Im definitely gonna keep an eye out for your new video on how this trimming and 37s are gonna do offroad. Your videos are awesome, could not have done the leaf springs and fox coilovers withot em.
As for tune I highly recommend going goosetuned through cobb. Much better than the cobb ots tunes. Smooth smooth power delivery and the man dials in your truck based on your fuel.
Potato Spud thanks man. Yeah, I ran the Cobb tune before and hated it.
@@KeepItDirtyOffRoad
Potato Spud is correct, Goosetune is the way to go and he does the transmission too. Everyone loves the power and buttery smooth shifting that his tunes deliver.
sixshooter4570 will have to look into them. Cobb left a bad taste with me with how much they charged to add the transmission tune. Early adopters should have been Grandfathered in .
@@KeepItDirtyOffRoad
I agree.
Where you get headlights? Looks great 👍
M&O Cleaning those are AlphaRex Nova series Alphas in all black. Highly recommend them. I have a few videos of them on the channel
What lift size did you need to run 37's?
Thank you
Never put a lift on a Raptor. Ever.
I think that if Ford released a Raptor with slight factory modifications to fit 37" wheels, people would then find a way to trim off something or other, lift an inch or two, and get 39"s in there xD
They trying it now with the Gen3 and some trying to do 40s since it can clear 37s
Just run BFG ko2 37s they are a little smaller than true 37 and u can run a matching spare under the bed.. basic trimming mods on the front. Contact Baja HQ they install 37s on raptors all day everyday and then do baja tours with the customers trucks they build with no issues
But then you would be stuck with the worst tire for these trucks 🤷♂️.
Baja HQ does the typical trimming we did in this video series. But they don’t trim and move up the trim like we do. For most scenarios that will work. But at full tuck, you can get into issues and that’s why we showed the trimming needed to make sure you you don’t rip off your fenders.
Should have let me know man I would have let you borrow my pneumatic hammer might have helped? 37s look awesome great work!
SERGIO ACEVEDO 🤣🤣 probably could have. It does not help how weak I am though.
Keep It Dirty Off-Road you are just starting a new enterprise. Raptor workout academy hahah
SERGIO ACEVEDO 🤣🤣🤣 come destroy your hands with us so you can drive slower and not damage your trucks after upgrading to 37s 🤪
Keep It Dirty Off-Road id look into regearing should take you back to stock then with a tune boom!
SERGIO ACEVEDO yeah, I need to look into it.
I put 37's on my gen 1 raptor and it barely rubbed, put it on top perch and now it doesn't rub at all. I suppose another reason the gen 1 is better?
Not really man. Once you fully flex that suspension, you will rip off the stock fenders. First truck I ever saw with 37s and the typical no rubbing attitude was a Gen1 and he ripped off his fenders at full tuck and caused some major damage to them.
@@KeepItDirtyOffRoad Yeah I've heard it destroys it as well but just driving 95% on the street it is no issue, but I plan to get some fiber glass 2in flare fenders soon so I have no worries at all.
@@Rocky-ry4lx ah ok. Make sure you clarify that next time. A lot of people ask about rubbing are asking for off-roading do you see rubbing. Trimming for street and trimming for off-roading are 2 very different things
@@KeepItDirtyOffRoad Yeah my bad, just gen 1 vs gen 2 banter hahaha
Another great vid! #paytheman
So the Fox suspension you have doesn’t add any lift?
The stock suspension does not. Remember it’s not the shocks that hold the weight, it’s the springs. So I upgraded to Eibachs springs up front for 1.5 in raise and XHD Deavers out back for 3 in raise. Still getting a bunch of subbing with stock fenders
Do you Recommend a catch can?
I get asked this question a lot. For me jury is still out on catch cans. For the most part turbo engines are designed to burn a little bit of oil as part of their normal operation. Reducing how much gets burned is a good thing BUT there is no solid information out there on the actual benefits of a catch Can. I’ve seen more bad than good actually because it’s hard to distinguish between a well designed system and a bad one. At the end of the day, there is no solid info out there to show me the benefits aside from catching oil so it’s going to stay off my truck.
@@KeepItDirtyOffRoad Catch cans catch a few tablespoons of oil a month that would normally flow into your intercooler. Why not? great insurance for 120 bucks.
R OK, that’s what I hear everyone say. But even with a catch can you can’t avoid it all. And I’ve read other complain of catch cans causing codes or loosing power after installing at Catch can. Personally, I would rather not risk it. The companies that makes them for the most part are not engine builders or designers. Catch cans are easy to make and they copy designs and don’t do any proper testing. Differentiating between a well designed catch can and a bad one is also difficult. So I’m not taking the risk on my truck
Hey Ford...
Fix that.
Way more room 👍
Anyone having front diff issues with the larger tires?
Would +18 still be able to fit upper control arms?
It’s going to be tight. I would not recommend it. We know the icon wheels at +6 can clear. But 18 would be way too close for comfort. Specially airdown
@@KeepItDirtyOffRoad do you think the methods you had with +6 would fit an upper control arm?
We know +6 wheels clear. But method does not make +6 wheels with the ford 6x135 pattern. Your only option from Method is 0 offset and that will more than clear.
@@KeepItDirtyOffRoad thank you I will look into those icon
What difference did you see in gas mileage with the 37's vs 35's?
Went from 14-16 MPGs down to 11-12 MPGs. There is a big impact.
Keep It Dirty Off-Road makes sense. Thanks for the info
I could see putting the 37's on a super duty but that's it. 💪⬅️😉😉
Ragrle Graggle can’t deny they look good on a Raptor. But they may not be worth the headache
How do you fix the speedometer
Guy Carroll I thinks that’s available online using ForScan. I’m ok with leaving it as is so the truck miles are lower than actual
I recommend checking out Rhino wheels also
EJ do you mean black rhino?
I've seen black rhino wheels break, but that was also jumping a 9000 pound mega cab repeatedly. Im sure the raptors wouldn't be as bad.
Joe Hansen I’ve seen plenty of wheels Granade
on the Raptor. The 4WP initially worried me, but they have a lifetime structural warranty so if they break I should be good.
@@KeepItDirtyOffRoad I've had good luck with my racelines. Cast wheels can only handle so much. Its only a matter of time.
Joe Hansen yeah, I agree but tire pressure and all that are a factor too. I bent 3 forged wheels running too low of a pressure
What headlights are these
Those are the AlphaRex LED headlights. We have a video on the channel where we compared them to the Morimotos too if you want to see what will work better for you
Does anyone make inn liners for McNeil racing fenders?
I though McNeil did their own. If now it can’t be too hard to adapt the ones from ADV. We had to cut ours when we installed them on our Gen1
I didn't see them on there site for the 2+2 style.
@@KeepItDirtyOffRoad By the way love this channel.
Thanks man. Give them a call see what the options are. Worst case you get a set of ADV liners and just be ready for some trimming.
@@KeepItDirtyOffRoad Will do . Greatly appreciated.
It’s crazy to think how the hell Ken Block is running 40s on one of his Raptors. Check his latest fleet video.
SoCal Trail Trekkers 🤣🤣 I know right! If you look at his video where he first showed off the SVC truck, he was getting a lot of rubbing. He even ripped off part of a fender at some point.
I think I’m gonna stick with my 40s
If you are after looks with a bigger tire then go for 63" dude!
🤣🤣 this video series is to show everyone what it actually takes to offroad with 37s on a gen2. Lots of bad info out there.
Well thats it....im scared. No 37s for me 🤣
🤣🤣 make sure to check out the followup videos where we test it and later did some more trimming to make it work. I still expect more maintenance but we got it to work.
Ouch 😣, all that cutting...
Marty Bober that’s just the start man. More will be needed I’m sure once we start testing it
I know from experience,, it is not worth doing this.. IMO you will affect the resale value of the truck too.. because there is no going back...
I say it in the video too man. If it were my money, I would have stayed 35s. But I had 2 sets of 37s given to me and was tired of seeing all the bad info online about them. Too many saying it will work without trimming, or with a perch and it’s all just not true
Holy god ads
minds didnt lose any power
Then you butt dyno is way off then. Most common thing everyone reports is the low of power.
@@KeepItDirtyOffRoad maybe i did lose some power if everybody said they lost power
Guaranteed you did. I felt it right off the bat and I even added the Cobb tune to compensate. Cobb tune helped at the low end. But on the high end power really dropped off and offroad I could not get my truck over 95 mph. Truck just did not have the power to pull away on the dry lake beds anymore. 37s need regearing and a tune to compensate. When I took mine back to 35s, it was a huge difference. Truck went from sluggish to feeling like a sports car again
@@KeepItDirtyOffRoad how much is that cobb tune thing
Easy to find the Cobb tuner online. I think it’s like 1200 now with the transmission tune. I had just the engine tuned and I did not like. But heard when matched with the transmission tune is much better
haha uses a plastic malet
and then an axe dear god
Only sledge we could find after going to Home Depot, Lowe’s, and harbor freight.
Most shops will use a long handle slide to bend them and make short work out of them. But no other way to do it.
@@KeepItDirtyOffRoad I’ve been on the ground slamming a pinch weld before. Not fun 😂
Do you have a video reviewing the performance of the Eibach springs. I know they are off now.
Enjoy your content man. Just found you and will keep watching.
No, I have not done a long term review yet. In the 37s series though you can see how they perform. They did great on my truck. Stiffer than I expected offroad and did well enough for me I did not want to do the Geisers at all on this truck.
It’s a horrible idea... you have to upgrade your suspension.. you have to reset the lower control arms too... everyone skips,, or don’t even know,, if you raise the perch on your shocks,, you are stupid.. yea it works,, but not for long
Totally agree. Check out the rest of the video series to see the results of our testing. We tested a lot of this bad info and found a way to make it work with spring upgrades.
