Product Description

The Fabtech FTS6338 Stealth Monotube Shock Absorber is a high-performance front shock designed for lifted heavy-duty GM trucks - specifically 2011-2017 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD and 2020-2024 GMC Sierra 2500 HD/3500 HD models. These monotube shocks feature a robust 50 mm seamless steel body and a 46 mm high-flow piston with vehicle-specific valving, providing reliable damping performance on lifted front suspension systems with approximately 6" of lift. The full floating internal piston separates gas from shock oil, helping maintain consistent ride characteristics and reducing shock fade under demanding conditions.

Fabtech's signature Stealth design includes a corrosion-resistant 14 mm Nitrocarb piston rod and an all-black finish with a raised nameplate for both durability and a premium look under your vehicle. Ideal for off-road enthusiasts and daily drivers with oversized tires and lifted suspensions, the FTS6338 helps improve front ride control and handling. Professional installation and wheel alignment after suspension component changes are recommended to ensure optimal performance and even tire wear.
