Rancho RS90000XL 1.5″ Rear Lift Shocks for 1973-1986 Chevy C-20 2WD

Part Number: RS999118

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the Chevy C-20 through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or hauling. Engineered to accommodate a 1.5-inch rear lift, this nitrogen-gas charged solution provides the precise control needed to manage the high center of gravity and varying load demands of classic C-Series trucks.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping force to ensure custom-tailored ride control for various road conditions or trailer weights.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance during heavy-duty cycling.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during sustained hauling.
• Polyurethane Bushings: High-density polyurethane material provides enhanced durability compared to standard rubber to ensure long-term pivot point stability.

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 body. You can simply turn the dial by hand to any of the nine numbered positions to change the damping firmness.

Do these shocks provide the 1.5 inches of lift?
No, these shocks are specifically valved and sized to work with a vehicle that already has a 1.5-inch lift installed. They do not create lift on their own.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS999118_n128) includes two shocks to cover both the driver and passenger side of the rear axle.
