I'm sure the question everyone has is do I rub... The answer is complicated lol. During street driving at suspension ride height I only rub at full lock to the left. I rub the passenger side tire against the front TRD red sway bar (Removed off the truck as of 4/29/2025). I do plan on removing this eventually before my first off-roading trip, but for now its super manageable because if I just back the steering from full lock just a bit it doesn't rub. And its only to the left it does this. I do not rub what so ever against the body mount or fender liner, just the sway bar. I dont know for sure if I would rub against the body mount at full suspension flex, but with how much space there is at ride height I dont think I will have any issues.

This is what I had to do to fit the 37s. The CBI Baja bumper was a no brainer, otherwise I would have had to trim a good bit of the OEM bumper. I had a shop in Sacramento, CA named stellar built relocation my body mount. This was not a chop... They cut off the OEM body mount COMPLETELY and welded on a part they made themselves which gave me a lot more room back there. I also had them do their "pinch weld service" which includes flattening the pinch weld and molding the fender liner back. I also installed coastal offload's bumpstop spacer kit myself. Yes this does unfortunately limit up travel by half an inch, but I was ok with it since the coach builder spacer I have gives me half an inch of extra droop. I definitely didn't have to do the bump stop spacer, but everyone I have seen with 37's rub against the top of the fender liner just ever so slightly. I didn't want to risk the accidental fender liner delete mod lol. I will end up removing the bump stop spacers if I ever end up getting fiber glass fenders.

Would I have done anything differently? Yes... I would have gotten my Methods in a +35mm offset they offer instead of the 0mm. This would for sure help with clearing larger tires, but I wanted the stance and didn't know that more negative offset makes it harder to clear larger tires at the time.

What's next for my build?
For stage 2 the first thing I need to get is hands down rock sliders and get the OTT tune. After that im probably gonna get switch pros and get one of the new ARB brushless twin compressors. After that is gonna be lockers and a regear. Right now im on the stock 4.30 gears and the truck honestly drives fine. A lot of people say that unless you regear you wont be able to use 6th gear. I have found this to not be true in my case, my tranny shifts into 6th around 60-65mph on the free way even when I use cruise control. It only downshifts if I go to accelerate. I still wanna regear to make the truck feel like how it was from factory. Acceleration has for sure gotten worse. I am still debating on 4.88s and 5.30 gears though. For the lockers I wanna do the ARB air lockers front and rear since I will have the switch pros and an ARB compressor already by then. Finally I will probably get some lights too
For stage 3 I wanna do a bed rack and roof top tent. Rear bumper. Fiberglass fenders and maybe bedsides too. A winch. And who knows, if I have lost all touch with reality by then I might end up putting a whipple on too!

Heres some more angles of the truck

Let me know if you guys want pictures of any of the suspension components or other angles of the truck!

 

You got a nice looking truck.

 

Definitely looks badass.

 

Looks nice!

Have you measure what's the center of your wheel to the fender opening?

 

100% 5.29s, even if you had smaller tires 5.29s would be the go to.

 

Whipple! Or Turbo should be the next addition so you can turn those monster tires!

 

Thanks for the input. Definitely been leaning a lot more towards the 5.29's!

 

Don't temp me lol! I have whipples website book marked on google chrome

 

Not yet, but I will do it as soon as I can and let you know!

 

I triple dog dare ya!!!
