lift kit question
Usually, the suspension systems are completely different, like on the 97-03's. I know the 04-08 trucks use the same suspension systems, but I'm not sure if the lifts interchange because I've never seen anyone try it. I know that the 2500HD GM trucks use the same suspension on 4x4's and 4x2's and I've seen a couple of lifted 4x2's in truck magazines that used 4x4 lifts. Apparantly it worked fine and they just had a few parts left over.
CST makes a 7" lift for 2wd. and it does replace the spindles. i think most kits do.
