whats the biggest tires i can go with a 4 inch procomp lift and a 3 inch body right now iam running 35s without the body lift and no rub. will i be able to fit 37s please help

 

I dont think so, I ran a fab 6 and 3in body with 37s on my 01 and I had to do a TB crank and trimming. I would think a 35 or 36 max, the thing that sucks on this body style is you cant trim the back of the wheel well very much because it shares the interior cab's sheet metal.

 

what is a tb crank agian

 

Torsion bar crank to add more lift in the front.
There's people around here with MASSIVE lifts that aren't running 39" tires. Lifts so big the tires aren't anywhere near the fenders.
Why so big?

 

for flex

 

ohhh. you a crawler or just do the flex competitions

 

used to do flex comps

 

you will get less flex with bigger tires....meaning if you put 35s with the 4susp and 3in body you will achieve more flex because of the additional fender room

 

iam not looking for flex now just look and proformence in the mud ok what i have is a 05 chevy 1500 extcab 4x4 with a procomp 4 inch lift and i dont want to but a whole new lift on just want to fit 37s now this is what iam looking to buy
