[Ladyzm18]

Doing the 5 to 6 lug swap with 2500ld rotors and axle. Just scored these wheels free tires are pretty shot. I only have 2" shackles in rear installed, have hangers to get 4" out of rear. Also have 2" bell tech spindles to go on can some one point me in correct direction for a tire set up looking for a staggered set up..

I think you're gonna have problems up front with the backspacing on those wheels.

All of the GMT800 and later wheels have a huge amount of backspacing due to a wider track suspension. Your potential issue is the wheel rubbing on the backside. Exactly where or how I can't tell you, but I can say that trying to use those wheels on a stock height GMT400, I ran into things like the wheel hoop (aluminum) rubbing on the end of the upper control arm. With the steel wheels the tires would rub on the frame at full lock. It's been a few years so memory is vague, these were just wheels I was using on parts trucks in the yard, not any of my own personal projects. But again, the main issue is the backspacing, they are similar to GMT400 4WD wheels in that respect.

My main goal was to run GM ltz 20" wheels do you know of any webpage that may give stock wheel backs pacing so I can see what wheels may work?
