Rancho RS9000XL 0″ Rear Lift Shocks for 1988-2000 GMC K2500 4WD

Part Number: RS999190

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC K2500, featuring a 9-position manual adjustment knob that allows drivers to tune their ride profile to specific environments. This adjustable design solves the compromise between daily street comfort and the firm damping required for heavy towing or off-road excursions. Engineered for vehicles at stock ride height, these shocks provide a custom-tailored suspension response that adapts to your specific load requirements.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure precise control for everything from highway cruising to heavy-duty hauling.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during sustained cycling.
• Nitrogen Gas Charged: High-pressure gas optimization provides a consistent damping response to ensure reduced aeration and foaming in demanding conditions.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure longevity against road debris and corrosion.

Why Choose This Product?
