Add this 6" RTS Lift Kit by Fabtech to your Sierra for an added 6" in height!

Fabtech’s cutting edge RTS™ system utilizes a patent pending bracket system that keeps the torsion bars raised up, in their stock location. In doing so, superior ground clearance is maintained as there isn't a torsion bar hanging below. The 6” RTS™ system has been designed with its own brackets in order to retain the four front compression stops of the vehicle as GM intended, further distributing impact loads more evenly.

High arched cross members and front differential skid plates are constructed using 1/4” thick steel as that provides the rigidity and strength necessary to relocate the torsion bars, bump stops and lower control arms properly.
The 6” RTS™ system allows the use of both 18” and 20” diameter wheels.
