Rancho RS9000XL 0″ Lift Shocks for 1973-1986 GMC C3500 2WD

Summary: The Rancho RS9000XL series is the industry leader in adjustable damping, providing GMC C3500 owners with unprecedented control over their ride quality. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly transition from a soft street ride to a firm setting for heavy towing or hauling. Engineered for vehicles at factory ride height, this set delivers a customized suspension feel that adapts to your specific load requirements and driving conditions.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect balance between comfort and control for any terrain.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure cooler operation and reduced fade during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charging provides a faster response rate to ensure consistent tire-to-road contact.
• Polyurethane Bushings: Durable polyurethane material provides enhanced durability and responsiveness to ensure long-lasting performance under load.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features an external 9-position knob located at the base of the shock body that can be turned by hand to increase or decrease damping resistance.

Do these shocks provide any lift to my GMC C3500?
No, these shocks are configured for a 0-inch lift and are designed to replace factory-length shocks without changing the vehicle’s ride height.

What is the benefit of the larger shock body?
The 2.75-inch diameter body holds more oil than standard shocks, which helps dissipate heat more effectively, preventing the shock from losing “firmness” during long trips or heavy hauling.
