hey man i have pretty much the same truck but have the pro comp 6" and you should have no problem with the 33s. Just make sure you have the whole kit, dont skimp or you will be sorry and will be replacing axels and ujoints like crazy because of the angles
Yeah, double what he said.
I actually take my yukon offroad daily and these things break parts easily if you dont do it right the first time.... almost like it rejects poor quality stuff..
Also, do you have a v8? if so, dont underestimate the power of it, its got alot of grunt and can snap a cv or drive shaft faster than you would ever imagine.
Gearing seems fine so far, the standard locking diff is pretty damn good, but if you plan on crawling, i would invest in some beefier gearing, afterall, these trucks are glorified minivans as opposed to dedicated 4wd machines. They do have alot of potential but you are going to spend some cash to make them solid offroad.

Hey i was wondering if there was anything special things required to lift my 2001 GMC Yukon SLT. I have the wheels and tires sorted out (33" Tire 17" Wheel all with proper backspacing) I'm getting a Trailmaster 6" Suspension lift (6" front 4" Back trailmaster classify's this as a 6" so thats what i'm calling it) and just want to know if there is anything special i need or problems i may run into lifting it? It is a 4x4 not that i think it will make a difference. Any feedback?
Thanks.
btw, can you let us know what you think of that lift after you get it installed and actually put it in the dirt?
