I need to replace the rear shocks on my Trailblazer because they are leaking, and I figured that it is a good time to lift it as well. I want to use the Z71 shocks and springs, but I'm not sure which ones to get. I have a 2002 Trailblazer, and I just wanted to know if it is safe to use (or if they would fit) springs and shocks from a 2007-2009 Z71. I'd like that extra 1.5", but I don't know if those can be used on a 2002 Trailblazer. Anyone have recommendations?
