Summary: The Rancho RS9000XL series provides unparalleled ride control for the Chevy Avalanche 1500 and GMC Yukon. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow drivers to instantly tune their damping levels to match specific terrain or load requirements. Whether you are navigating daily commutes or hauling heavy trailers, this nitrogen-gas pressurized system delivers the versatility needed to bridge the gap between street comfort and off-road performance.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure precise ride control across various towing and hauling conditions.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent hydraulic performance during aggressive cycling.
• Large Shock Body: An increased fluid capacity design provides superior heat dissipation to ensure fade-free operation under heavy loads.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against trail debris.
