I just got a 2008 Silverado 2500 4wd Crew Cab with 6L V8 - it rides rougher than hell - my previous truck was a 2001 1500 z71 and I guess I got spoiled by its ride - I was expecting a stiffer ride but would like to smooth it out. My question is did they do the z71 on a 2500 and would just putting the Bilstein shocks on get me back to that smoother ride that I miss?
