Installed on a 2011 Z71 Silverado Crew Cab. According to the instructions, I inserted the rear bolts from below without touching the axle. Installation was pretty easy, I didn't knock out the bottom ball joint. Removing the stabilizer was enough to put the kit in place with relative ease. The entire installation from raising the truck in the air to lowering it and taking it off took 2 hours using hand tools. I'll update if there are further developments, but I don't see any problems unless there's a glitch. It had little effect on wheel alignment, although I'll have to do wheel alignment professionally soon, with the help of weekend mechanics it was immeasurable. Ride quality seems to have improved somewhat, particularly with less deflection on small but steep bumps, making the truck feel more planted.
