The 2011–2019 Chevy Silverado 2500HD and GMC Sierra 2500HD 2WD/4WD can be upgraded with Fabtech’s cutting-edge 6" RTS® System, engineered specifically for the redesigned GM HD platform.
This advanced suspension system features a patent-pending bracket design that keeps the torsion bars raised in their factory location rather than lowering them. By retaining the stock torsion bar height, the system provides significantly improved ground clearance and eliminates the risk of the torsion bars hanging low where they could become high-centered or damaged during off-road use.
