Rancho RS9000XL 1.5″ Rear Lift Shocks for 1987-1989 GMC R2500 2WD

Part Number: RS999118

Summary: The Rancho RS9000XL series provides industry-leading versatility for drivers who demand total control over their vehicle’s ride profile. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping levels to transition from smooth highway cruising to firm support for heavy towing or hauling. Engineered to accommodate a 1.5-inch rear lift, these shocks solve the problem of “one-size-fits-all” suspension by putting the power of customization in the driver’s hand.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride for street, towing, or off-road applications.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operation and consistent performance under heavy loads.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Heavy-Duty Piston: A 1.25-inch sintered iron piston provides structural integrity and long-term durability to ensure reliable service in demanding environments.

Frequently Asked Questions

How do I adjust the stiffness of these shocks?
The RS9000XL features a 9-position manual knob located at the base of the shock body. Simply turn the dial to your desired setting; lower numbers for a softer ride and higher numbers for increased firmness.

Do these shocks create the 1.5 inches of lift?
No, these shocks do not create lift. They are specifically valved and length-matched to work with vehicles that have already been equipped with 1.5 inches of rear lift via blocks, springs, or shackles.

What is the benefit of the larger 2.75-inch body?
The increased fluid capacity allows the shock to dissipate heat much faster than standard 2-inch shocks, which prevents “shock fade” and maintains consistent handling during heavy-duty use.
