The Rough Country 2-3in kit for the 88-98 GM 1500 now includes Forged Aluminum Upper Control Arms with durable OEM style rubber bushings, proven to hold up to even the most rough and tumble trailblazers. These arms feature a set of upgraded POM ball joints that offer a greater range of motion for more articulation over standard or OE replacements, Polyoxymethylene ball race with an extremely low coefficient of friction for longer life, and a larger ball diameter to improve range of motion with a maintenance free design. This kit also includes N3 Shocks, forged torsion bar adjuster keys, a differential drop bracket, and rear fiberglass-reinforced nylon lift blocks.
