Hi I'm new to the site and I can't find a forum and the one I did the guy openly admitted he didn't even know anything about vehicles, I'm looking to lift my 98 c1500 2 1/2 to 3 inches, I bought it off my friend and he said there was a sports package suspension put into it that's why it sits higher already but the torsion keys are not cranked I'm running 285/75/16 mud terrains without any rub. I was going to buy different keys and a diff drop kit any suggestion on keys or diff drop kitts?
