Rancho RS9000XL 0″ Rear Lift Shocks for 1988-2000 GMC K3500 4WD

Part Number: RS999190

Summary: The Rancho RS9000XL series provides industry-leading adjustability for GMC K3500 owners who demand versatility from their heavy-duty suspension. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for towing or hauling heavy payloads. Engineered to handle the high-stress demands of 4WD applications, these shocks deliver consistent damping performance and heat dissipation under load.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can fine-tune ride quality for specific road conditions or trailer weights.
• Large Diameter Body: A 2.75-inch heavy-duty reserve tube provides increased fluid capacity to ensure lower operating temperatures during sustained cycling.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent valving response across rough terrain.
• Polyurethane Bushings: High-performance polyurethane mounts provide enhanced durability and reduced deflection to ensure precise axle control.
