Product Details

The 2011–2019 Chevy Silverado 3500HD and GMC Sierra 3500HD 2WD/4WD can be upgraded with Fabtech’s advanced 6" RTS® Suspension System, newly engineered for the GM HD platform.

This system features a patent-pending bracket design that keeps the torsion bars mounted in their stock, raised position. By eliminating the need to lower the torsion bars, the system delivers significantly improved ground clearance and reduces the risk of the torsion bars becoming high-centered or damaged during off-road use.

Stealth Monotube Shock

Stealth shocks are the industry’s first all-black monotube shock absorbers, recognized by their raised metal nameplate that signifies premium craftsmanship. These shocks use a 46mm high-flow piston and vehicle-specific valving to deliver excellent ride quality and control, especially when running oversized tires. Their Nitrocarburized piston rods outperform traditional chromed rods in durability and corrosion resistance, all finished in matte black for a complete blackout look.

50mm OD Seamless Steel Body
46mm High Flow Piston for Best Ride
Vehicle Specific Valving Designed for Oversized Tires
Full Floating Piston Separates Gas from Oil for a Consistent Ride
14mm Nitrocarb Piston Rod Resists Rock Chips and Rusting
All Black Finish with Raised Nameplate as a Signature of Quality
