Rancho RS9000XL 0-2″ Rear Lift Shocks for 1969-1972 Chevy K-20 4WD

Part Number: RS999118

Summary: The Rancho RS9000XL series defines versatility for classic heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow owners of the Chevy K-20 to instantly transition from a soft street ride to a firm setting for towing or off-road stability. This adjustable damping technology solves the “one size fits all” compromise of traditional shocks, providing custom-tailored ride control for various load demands.

Features

• 9-Position Tuning Knob: Manual adjustment dial provides nine levels of damping force to ensure the perfect ride quality for any terrain or load.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent performance during heavy use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure the tires maintain contact with the road surface.
• Protective Boot: Included heavy-duty bellows provide a physical barrier for the piston rod to ensure long-term seal integrity against debris.

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. Simply turn the dial to your desired setting; No tools are required.

Does this shock provide the 2 inches of lift?
No, these shocks do not create lift. They are specifically configured with the correct travel and lengths to accommodate a vehicle already equipped with 0 to 2 inches of rear lift.

What is the benefit of the larger shock body?
The 2.75-inch body holds more oil than standard shocks, which helps dissipate heat more efficiently, preventing “shock fade” during prolonged use or heavy towing.
