Part Number: RS999377

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC Sierra 3500HD, featuring a globally recognized 9-position manual tuning system. This adjustable damping technology allows drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered to handle the high-demand loads of a 1-ton truck, these shocks provide a custom-tailored suspension response without requiring component changes.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure precise control across varied towing and hauling conditions.
• 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 performance.
