Fellas, I have an 08 Z71 extended cab and was thinking about putting the leveling kit on the front so I can fit a slightly larger tire on the stock 18" wheels. First question: will the leveling kit affect the ride quality of the Z71 suspension? I really like how it rides now and if it's going to make it dramatically more harsh I might not do it. Second: a 33" tire is about the biggest I'm going to be able to fit without any rubbing/clearance issues right? Or can I go up to a 34?
