Back to List
Included Shocks

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.

Stealth Shocks

Stealth is the first all black monotube shock absorber, with an identifiable raised metal nameplate, that represents the signature of quality you can rely on for a superior ride at an affordable price.

Stealth monotube shocks are built with a 46mm diameter high flow piston and vehicle specific valving, for a great ride with oversized tires.

All Stealth shock absorbers feature Nitrocarburized piston rods that are superior to chromed rods in durability and corrosion resistance. These “Nitrocarb” piston rods are finished in matte black for a complete “black out” shock package.

  • - 50mm OD seamless steel body
  • - 46mm High flow piston for best ride
  • - Vehicle specific valving designed for oversized tires
