Rancho RS9000XL 1.5″ Rear Lift Shocks for 1987-1989 Chevy R-20 2WD

Part Number: RS999118

Summary: The Rancho RS9000XL series is the industry benchmark for adjustable damping control, allowing drivers to manually calibrate their ride for any environment. Featuring a 9-position tuning knob, these shocks solve the compromise between street comfort and heavy-duty towing stability. Whether you are hauling a load or cruising the highway, this Tier 2 adjustable system provides the versatility to firm up the suspension for control or soften it for daily driving. Engineered for the rear of the 1987-1989 Chevy R-20, they offer a precise solution for vehicles configured with a 1.5-inch lift.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping force to ensure the perfect ride quality for towing, hauling, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure consistent tire-to-road contact.
• Heavy-Duty 18mm Nitro-Carb Rod: A hardened piston rod provides increased structural rigidity to ensure long-term durability under high-stress loads.

Why Choose This Product?

• Engineering Advantage: Unlike “one size fits all” shocks, the RS9000XL allows for user-defined valving, meaning the shock adapts to your cargo rather than forcing you to adapt to the shock.
• Performance Benefit: Eliminates the harshness typically associated with lifted trucks while maintaining the stiffness required to prevent swaying when the vehicle is fully loaded.

Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features a manual knob located at the base of the shock; simply turn the dial to setting 1 for the softest ride or setting 9 for maximum firmness.

Will these shocks lift my Chevy R-20 by 1.5 inches?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles that have already been equipped with a 1.5-inch rear lift kit.

What setting should I use for towing?
For towing or carrying heavy payloads, it is recommended to use higher settings (7-9) to increase damping control and reduce vehicle sway.
