FABTECH 6" RTS System with Stealth Shocks

11 - 16 Chevy / GMC 3500

by Fabtech


Fabtech’s cutting edge RTS® system has now been developed for the all new GM HD platform. The 6” RTS® utilizes a patent pending bracket system that keep the torsion bars raised up, in the stock location.

This feature provides superior ground clearance at the frame as there are no torsion bars hanging down to become high centered on or damaged when offroading.

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.
