Rancho RS9000XL 0″ Rear Lift Shocks for 1999-2007 GMC Sierra 1500 4WD

Part Number: RS999198

Summary: The Rancho RS9000XL series provides industry-leading adjustability for your GMC Sierra 1500 4WD, allowing you to customize your ride quality on the fly. Featuring a 9-position manual tuning knob, these shocks solve the common problem of a “one size fits all” suspension by letting you switch between a soft street feel and a firm setting for towing or hauling. Engineered for stock height applications, these shocks deliver premium control and heat dissipation for reliable performance under varying load conditions.

Features

• MyRide Tuning System: A 9-position manual adjustment knob provides nine distinct levels of damping to ensure the driver can fine-tune the ride for any terrain or payload.
• 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 charging provides a consistent response and reduces aeration to ensure fade-free performance.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
