April 13, 2011I recently bought a new truck that is a 2007 classic 2500HD and it is only a 4x4, and not a Z71...on my old silvy was a Z71 and the only difference I noticed was a skid plate(s). Can someone confirm this? I am looking to upgrade the new truck to it as well and wanted to know what else all went in with it.
ps. the new truck is a Dmax with bigger tires (285/75/R16) and stock T keys,leafs and shocks.
