Rancho RS9000XL 2.5-4″ Rear Lift Shocks for 1992-1998 GMC Suburban 2500 4WD

Part Number: RS999227

Summary: The Rancho RS9000XL series provides industry-leading versatility for the GMC Suburban 2500, featuring a 9-position manual tuning knob that allows drivers to adjust damping levels on the fly. This adjustable technology solves the conflict between daily street comfort and the firm control required for heavy towing or off-road excursions. Configured for 2.5 to 4 inches of rear lift, these shocks utilize a massive 2.75-inch body to increase fluid capacity and ensure consistent performance under load.

Features

• MyRide Tuning System: A 9-position manual adjustment knob provides custom damping control to ensure the perfect ride quality for street, towing, or trail 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 Pressurized: High-pressure gas charging provides a faster response time to ensure consistent tire-to-road contact on uneven terrain.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.

Why Choose This Product?

• Engineering Advantage: The RS9000XL is one of the only shocks in its class to offer a global damping adjustment that affects both compression and rebound simultaneously via a manual dial.
• Performance Benefit: Drivers gain the ability to “soften” the rear end for empty highway cruising or “stiffen” the valving to eliminate sway and squat when hauling heavy trailers.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
Simply turn the 9-position knob located at the base of the shock body. Position 1 is the softest for comfort, while Position 9 is the firmest for heavy towing.

Do these shocks create the lift for my Suburban?
No, these shocks are configured for vehicles already equipped with 2.5 to 4 inches of rear lift. They provide the necessary travel and length to accommodate that height.

What is the benefit of the large 2.75-inch body?
The larger body houses more hydraulic fluid, which helps dissipate heat faster than standard shocks, preventing “shock fade” during prolonged use.
