The 2011–2019 Chevy Silverado 3500HD and GMC Sierra 3500HD 2WD/4WD can now take advantage of Fabtech’s cutting-edge 6" RTS® System, engineered specifically for the updated GM HD platform.
This advanced suspension system features a patent-pending bracket design that keeps the torsion bars raised in their factory position. By eliminating the need to lower the torsion bars, the system significantly improves ground clearance and prevents the bars from hanging down where they could become high-centered or damaged during off-road use.
