I just found a video of Vaughn Gittin Jr jumping an RTR on true 35s and the front wheels tucked hard enough to rub the inner fenders just like my raptor. Ford actually made 37s fit the gen 3 raptor by limited suspension travel and also cheating by using 37s that aren't true to size. I guess that's the end of my want for 37s.This thread is literally about what fits, based on the extensive evidence gathered thus far. 37” fit in the wheel wheels with a 3” lift and approx +33mm offset wheels.
But the 1.1” lift found on Sas is at the end of the Bilstein/UCA/CV effective range, so if you want to go higher than that, you need new coilovers and UCAs.
Ryan from 4wp worked hard on the science of the Bronco lift, and I trust the conclusions he came to… he has the math to back it up. He has posted some videos on the forum with pages of technical discussions following. He brings the receipts.
(It’s worth noting that the 4wp rig with 37’s also has the fender flares removed… and some minor trimming in the wheel well.)
Though, depending on your style, you can contrast that with Loren Healey’s position on running 37”s, which can be summarized as (and I’m paraphrasing here): “2 inches up, 2 inches out, and f*ckin send it!”
