Quick Overview

Whether you are trying to win best in class at a truck show or first place at the local mud race, Fabtech has all you need to accomplish anything! The Fabtech patent pending 6” RTS (raised torsion system) bracket lift kit for the Chevy Silverado, GMC Sierra 2500HD keeps the torsion bars raised in the stock position. No more getting high-centered with the hanging-down torsion bars that could lead to damage when offroading.

This design has unitized bracketry to retain the 4 front compression stops of the vehicle just as GM intended. Rather than the impact load hitting a single point, this design distributes impact loads across a wide section of the frame. Minimal heavy-duty bracketry speeds up installation time with only 2 holes to drill and no cutting of the front differential housing. Included in the Fabtech 6” RTS bracket lift kit for the Chevy Silverado, GMC Sierra 2500HD are:

High Arched Crossmembers
Front Differential Skid Plate
Heavy Duty Ductile Iron Steering Knuckles
Four Performance Shocks
Heavy Duty Bracketry
All Necessary Hardware
