I'm wanting to put a set of 33x12.5 17 mud terrain tires under my suburban but it's at stock height so I was just needing to know what's the least amount of lift I could put on it in order for them to fit right? Would a 3" torsion key and a 4inch block be enough?

Thanks for all the info

 

If im not mistaken you can fit 31's stock . looks stuffy and rubs but it works.

torsion lift maxed out destroys everything under that truck suspension wise. Some will be lucky and things will not break, most do... .

Body lift will help and is much less $
imo wait till you have the proper money and get a suspension lift and do it properly.
