In 1988 GM was the first to produce an IFS 4wd truck with torsion bars, which has been an industry standard ever since. Fabtech offers a 6'' system for this vehicle that utilizes lower control crossmembers and extended length steering knuckle technology resulting in a quick installation and a great highway ride. The 1/4'' thick crossmembers feature Fabtech's boxed design for superior strength and include an integrated front differential skid plate. The crossmembers gain strength with impact struts to help distribute front suspension impact loads. Also included in this system are extended front and rear bump stops brackets, billet sway bar links, torsion bar drop brackets and more. The rear of the vehicle receives lift from a 4'' block and Add-A-Leaf system.
