Part Number: RS999379

Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty trucks through its globally recognized 9-position manual tuning system. Designed for the Chevy Silverado and GMC Sierra 2500HD/3500HD, these shocks allow drivers to instantly adjust damping levels to compensate for varying payloads and towing demands. Whether navigating unloaded highway miles or hauling maximum GCWR, this nitrogen-gas pressurized solution provides the precise control needed to eliminate pitch and roll in professional-grade applications.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure custom-tailored ride control for towing, hauling, or daily driving.
• Nitrogen Gas Pressurization: A high-pressure gas charge provides a reduction in aeration and foaming to ensure consistent performance during heavy-duty cycling.
• Large Shock Body: An increased fluid capacity design provides superior heat dissipation to ensure fade-free operation under high-load conditions.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a shield for the piston rod to ensure long-term seal integrity against road debris.
