How to fit 37's on a Raptor 

David Jordan thanks man. Really appreciate the support!!

Thanks man 🙏🙏. It’s a shame most of these trucks are used as just status symbols. It’s such a capable truck and I enjoy it and the places it’s taken me to. But it’s even better getting others out there to join me so I can show them what their trucks can do.

thanks man. Trying to provide some real info 37s. too much misinformation out there.

Smarter Than You On pavement it’s fine. But as soon as you turn the wheels or go over anything that moves the suspension and you get rubbing. Offroad, your ripping stuff off.

Keep It Dirty Off-Road roughly 35/13/17 when I said at speed I didn’t mean on the freeway. I live on a really shitty ranch road about 4 miles long I hit 70 on it about the half the times I came home from work.

Smarter Than You I’ve seen the 35s rub at full tuck. But it’s takes a huge jump or something like that.

AntRam I know that the icon kits limit some up travel and may be helping a bit. Carli kits for Rams for example do a really good job of letting you run bigger tires.

Thanks man. I put a lot of work into the videos, but I still have a lot to learn

It’s not just the springs and Deavers. Check out the rest of the video series for all the trimming. But be fair warned. We don’t recommend spring upgrades anymore due to very common failure we see with them because they add too much preload. We have an updated video on that. Basically you should do SDI shock bucket replacement for 1.5 lift up front and +3 Deavers outback. (+2 Deavers is just stock height)

Just Q the Raptors 4wd system is more like an AWD system and power is not distributed 50/50 like a traditional 4wd. Raptors 4wd is also unique in that you can go 100 mph in 4wd. All others are limited to 40 mph. So you can get away with just re-gearing the back. But honestly, with the way the 10 speed transmission works you don’t really need to re-gear.

YeH, clearance is similar on the Gen1 and they have less travel stock.

Cole Mizak same issues as with regular 37s. It’s only a small difference (0.25-0.5in) and rubbing is still a problem.

yeah, it's cambers long travel kit. I know a few that run it and you still have to do some trimming and at the end of the day once everything it included costs the same as most other mid travel kits that have more capability offroad.

@@KeepItDirtyOffRoad oh this is good info. Can you elaborate if yiu have a few minutes? Their kit comes in at about 5100 on sale right now from 4WP. includes axle, LCA, UCA and I have tie rods already. I don't need bumps or bypass because I'm staying at the Starbucks drive thru lol. I think the 1 inch forward and 1.5 out should be good with fiberglass fenders

Are you doing single or dual shock setup?

@@KeepItDirtyOffRoad single fox 3.0s

IMO, a single front shock version with a wider track is not worth it. Yeah you get more travel and all that. But you don’t really get to use it with a single coilover. You really need the extra bypass shock to help absorb the impacts and allow you to use the suspension trsvel as higher speeds. Your basically the cost of the bypass and arm and weld work off from a full bolt kit. Maybe $4-5k difference between a full mid travel kit. Spending all that money is not worth it, just go all in

There was a noticeable difference in how they performed yeah. A little smoother and you can feel the difference in the adjustment knobs. Only thing I did not like about them is the level of rebound they had. Shocks rebounded way too much than the stock ones. They definitely needed a tune to my setup. But that’s all shocks really. If you upgrade all 4 counters, a tuning session should be planned to get the best performance

Omar Ramirez you can, but there are a few problems with putting a bump kit up front. Reduced travel is a big one, up travel is what allows the truck to travel at high speed and cushion the bumps. So reducing that does reduce capability. 2nd is where to put it. Ideally a bump stop should strike at the Upper control arm, but with wiring, battery and intake there is no where to fit one. I’ve seen a lot of shops strike on the lower control arm but this is a compromise and may cause some issues with twisting overtime.

piancj the -15 offset may become a problem. Stock wheels are 34. -15 may require wider fenders to avoid ripping them off at full tuck.

Ryan Nolan 🤣🤣 not sure if that’s even an available size

@@KeepItDirtyOffRoad I think the BFG AT KO2 37 measures.out to a 36.xx? What I'm getting at is not all tires are manufactured true to size so if one could get a "small" 37 it would be better than a true 37.

Ryan Nolan your probably right.

@@freethinkingamerican80 seems like they are all a inch off -

@@freethinkingamerican80 That's correct - BFG 37"s for both the KO2 and KM3 measure out at 36.5. I've been debating the same thing...

Christopher Slager dude? I felt every hit in person. There has to be a better way, but so far I haven’t found it

@@KeepItDirtyOffRoad I'm sure there's a much better way if money wasn't an option! First hit, my jaw dropped, then I said no a couple of times... Then the wincing started. That was hard to watch... Seriously.

Christopher Slager I’m sure it would take 10 times as long too.

@@KeepItDirtyOffRoad probably... But you know the old saying... Patience is a virtue... Which I need to learn and understand myself! Lol!

Christopher Slager 🤣 you and me both. I’m not patient at all.

Fern Built working on it now. Will announce plans here soon.

Christopher Salmon 13.5s should be fine. Your only risk is that they will put you very close to the upper control arm UCA. You will not be able to upgrade your UCA until you get different wheels with 12 or lower offset. Then at that point your now getting wide again and risking messing up your fenders again. Stock wheels are at 34 mm offset.

Steven G yes they will, and do on my buddies trucks. It’s no where near as bad as 37s. But in full tuck worst case scenario situations you can see rubbing on the outer trim.

Keep It Dirty Off-Road thanks for the reply and all your entertaining/informative content 👍🏼

We have an update video on the channel on how to do it. You basically pry it off.

@@KeepItDirtyOffRoad copy, i got the block off ok, but the green foam adhesive is thick. Any tips for removing the adhesive would be awesome.

We scrapped it off what we could but this area gets covered up once we relocated the liners back in so we were not too worried about getting it all of.

@@KeepItDirtyOffRoad Right on. I ended up trying an aggressive wire wheel on the angle grinder and that took it off, but made a massive green mess lol. Thanks again for the great videos watched a bunch tonight. 👍

Glad we could help man. That’s our goal here on this channel

BlackGT1999 that’s the point of the video. If all you want is a truck with 37s to pavement crawl yeah it works. But too many of those guys tell people they offroad and it works. Then you get someone that doesn’t know any better follow their advice and they are causing major damage to their truck

Yes, even if you don’t offroad, you have to trim the corners closets to the door on both sides. It will rub when turning.

@@KeepItDirtyOffRoad okay perfect.. I think I’ll just trim the corners and call it a day lol

Depends on if you plan to offroad. Most go 0 and don’t realize stock is -34 and are surprised when the tires rub on the fenders at full tuck. -12 to -6 I’ve heard should mostly clear with only mild rubbing at full tuck. 0 offset you will be guaranteed rubbing and possibly rip something off at full tuck.

SERGIO ACEVEDO I agree. It’s why I resisted for so long

Blaine Kerner first of all thanks for being honest. Lots of guys say they do it for off-roading and only do it for looks. For looks just trimming the liner is a start. But if the wheels are turned while going over a speed bump or a curb you will hear and feel some rubbing. At the very least, the bottom of that pinch weld needs to be bent in and the liner pushed in a bit.

Charlie Brouillette Raptors come with 35s stock. The stock wheels are 34 offset so really deep in there. 18mm should be fine.

Keep It Dirty Off-Road thanks you for the quick reply, helps a lot. Love you channel man great content👍👍

Charlie Brouillette thanks man. Totally appreciate and glad I was able to help

Truck had stock rims in this video and it was super tight.

At this point in the truck build I also had the Cobb tune and I was able to correct the tire size and have the correct speed. Problem here is 2 fold.: 1. 4.10 gearing is totally wrong for 37s. Should be 4.55 or 4.88 2. The way the ecoboost makes power. All up front and sharp drop on the big end. So after 65mph, there is no more power left to give and she’s already bogged down. The 2022 ecoboost handle it better but still get bogged down and why 37s on a V8 truck are better. More torque early on and power curve is more linear.

@@KeepItDirtyOffRoad Thanks for taking the time to break it down !!

WB Streets you would reduce travel and now you need something more crazy up front that can support a bump stop. I’ve been a few front bump stop options out there but they all take away way too much travel and not worth it. It also won’t stop the rubbing. At full tuck you only risk hitting the pinch welds and liner. But at normal ride height your hitting fenders and everything when turning. Add a small bump while turning like a speed bump and even with trimming you got rubbing. It’s really not worth it and mainly done for looks rather than functionally at that point

Eventually yes you do. The truck will drive sluggish until you do. Even on age 1s. It’s on the list of things to do to mine

Sure, if you want to be made fun of at every Raptor forum or event. NEVER put a “lift kit” on a Raptor. You loose all the offroad functionality of the truck when you do.

@@KeepItDirtyOffRoad what do u recommend I’m trying to change the look of my stock raptor Want to make it look more aggressive

Depends on your budget and how much off-roading you want to do. There are low cost options we documented on future videos of this video series. And there is the right way that requires big bucks

Yep, totally agree

Lol. No. They changed a lot of the frame components and upgraded the shocks. But if you look at the specs, suspension travel and all the is very limited. That means that I order to clear everything they had to limit up travel. They also kept the same steering. The steering is going to be a problem offroad with all that extra rolling weight.

35s really are more than enough. Specially considering the power loss and all the extra maintenance. We did a few updated videos on it as we trimmed and tested our 2020 raptor

jairo lopez 12.5s are w much better choice. But 37s and 20s offroad is a bad mix. 20s period for off-roading is just not a great option.

Keep It Dirty Off-Road yup they are a bad choice only have them for light use when I really need to use it with the Utv’s I slap on the stock rims and tires

Land Lord agreed. The point of the video is to dispel the myth that you can do it with just spacers and some light trimming

So many reasons. 🤣🤣 Fuel economy being the #1 reason

Krasnaludek totally agree. A lot of people do it for looks. For me it had to be functional and the cost to make the truck functional with 37s is way too high

🤣🤣🤣 if all your doing is mall crawling sure!! Check out the rest of the series. We tested the typical BS advise like yours and man are you soo wrong .

🤣🤣🤣 39s are they nee black. Yeah I know but damn is the suspension to handle those crazy and you basically can’t fit on any normal trail.

Check out the latest video. We shows what’s really needed and put on some decent wheels and tires

This video was made before that was even an option. 🤷‍♂️. And even still it’s the most common question on the forums 🤦‍♂️

SCRAPtor 1023 🤦‍♂️🤦‍♂️🤦‍♂️ zebra 🦓 pattern the whole truck!!!

@@KeepItDirtyOffRoad I'm working on doing something... *evil laugh* 😂😂

SCRAPtor 1023 zebra 🦓 🦓 yes!!!!

Never paint it

🤣🤣 sure, if you only running to the mall or Starbucks.

🤣🤣🤣 not possible. Not even with stock offset at +34. Aftermarket you can only get +6, 0 , or negative offset that goes much wider. 37s with stock wheels will rub on the corners. 37s with 0 offset rubs a little more. Even if you use BFG, that we all know are smaller than 37s, they will rub. NONE work offroad. NONE. And I showed the proof in multiple follow up videos. I have a few videos showing the rubbing. And a 2 in lift can be too much for the front axles and now the CV boots will fail quicker. So sorry man, but your advice here is all kinds of wrong and I’ve proven it.

That’s what she said! 🤣🤣🤪 Sorry had to do it. But yeah man. That’s what it takes to offroad a Raptor with 37s. Anything else and your ripping fenders off eventually.

@@KeepItDirtyOffRoad 😅

Ramon Vega only an completely insecure man would focus on another mans height. What are you jealous of man? That my truck is better than yours? Or is it something else much, much smaller on you. What ever it is, keep hiding behind you small existence online.

@@KeepItDirtyOffRoad ahhahahaha 🤣🤣 something else much smaller
