Part Number: RS999190

Summary: The Rancho RS9000XL series provides industry-leading adjustability for your GMC C2500, allowing you to manually tune your ride quality to match specific driving conditions. Featuring a 9-position manual adjustment knob, these shocks solve the compromise between daily street comfort and heavy-duty towing stability. Engineered for vehicles with a 4-inch rear lift, they deliver a custom-tailored damping response that adapts to your cargo and terrain requirements.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect balance between soft street cruising and firm load-carrying control.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance during spirited driving or heavy hauling.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures during demanding use.
• Polyurethane Bushings: High-density polyurethane material provides improved durability and reduced deflection to ensure precise axle control.

Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features an easy-to-reach 9-position knob located at the base of the shock, allowing for manual tuning without tools.

Do these shocks create the 4 inches of lift?
No, these shocks are specifically configured for a vehicle that already has a 4-inch rear lift kit installed; they do not provide the lift themselves.
