Product Details

The 2011–2019 Chevy Silverado 2500HD and GMC Sierra 2500HD 2WD/4WD can now be equipped with Fabtech’s cutting-edge 6" RTS® System, engineered specifically for the latest GM HD platform.

This advanced suspension design features a patent-pending bracket system that keeps the torsion bars raised in their factory position rather than lowering them. By maintaining 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.

Featuring a 46mm high-flow piston and precise vehicle-specific valving, they deliver excellent ride comfort and control—especially with oversized tires. Their Nitrocarburized piston rods provide superior durability and corrosion resistance, all finished in matte black for a complete blackout appearance.
