I'm currently looking at the Rough Country leveling kit that comes with shocks front/rear, torsion keys, and 3/4" spacers for the rear springs to allow 33s. However, I'm confused as a neighbor has an Avalanche on 33s with torsion keys and 2" spring spacers in the rear and it sits perfectly level. His isn't a Z71 model though. Do the Z71s have stiffer rear springs? Current measurements show the rear of mine to be 2.5" taller than the front when measuring from the ground to the top of the wheel wells.
I've attached a side by side comparison using the rear view mirrors as reference.
