Rancho RS9000XL 0″ Rear Lift Shocks for 1988-2000 GMC C2500 2WD

Part Number: RS999190

Summary: The Rancho RS9000XL series provides industry-leading adjustability for owners of the GMC C2500 and Yukon. Featuring a globally recognized 9-position manual tuning knob, these shocks allow drivers to instantly convert their ride from a soft, compliant street feel to a firm, controlled setting for heavy hauling or towing. Designed to fit stock height applications, these shocks solve the compromise between empty-bed comfort and loaded-chassis stability.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure the perfect ride quality for any load or terrain.
• Nitrogen Gas Pressurization: High-pressure gas charge provides a consistent response by minimizing air-to-oil mixture to ensure fade-free performance during heavy use.
• Large Shock Body: A massive 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during long-distance towing.
• Sintered Iron Piston: A heavy-duty 18mm nitro-carbonized rod provides increased structural integrity to ensure long-term durability in harsh environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock body. You can simply turn the dial by hand to increase or decrease damping resistance.

Will these shocks lift my GMC C2500?
No, these shocks are configured for 0-inches of lift and are designed to replace factory-length shocks while maintaining original ride height.

What is the benefit of the large 2.75-inch body?
The larger body houses more oil, which helps dissipate heat faster. This prevents the shock from becoming “mushy” or losing effectiveness when driving on rough roads or towing heavy trailers.
