Rancho RS9000XL 0″ Lift Shocks for 2014-2019 GMC Sierra 1500 Old Body

Part Number: RS999830

Summary: The Rancho RS9000XL series provides industry-leading versatility for the GMC Sierra 1500, featuring a globally recognized 9-position manual adjustment knob. This system allows owners to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Designed for vehicles at stock ride height, these shocks solve the compromise between daily comfort and work-ready performance.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the driver can tune the ride for specific payloads or terrains.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent damping response under rapid cycling.
• Polyurethane Bushings: Performance-grade polyurethane material provides enhanced durability compared to rubber to ensure long-term pivot point integrity.
