Rancho RS9000XL 4″ Rear Lift Shocks for 1999-2006 Chevy Silverado 1500 4WD & Hummer H2

Part Number: RS999269

Summary: The Rancho RS9000XL series delivers industry-leading versatility for drivers who demand total control over their vehicle’s ride profile. Featuring a 9-position manual tuning knob, these shocks allow you to instantly adjust damping levels to compensate for heavy towing, off-road excursions, or smooth highway cruising. Engineered for vehicles with a 4-inch rear lift, the RS9000XL provides a custom-tuned solution that eliminates the compromises of traditional fixed-rate shock absorbers.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride quality for any load or terrain.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure consistent damping performance under rapid cycling.
• Polyurethane Bushings: High-performance polyurethane material provides enhanced durability and pivot-point stability to ensure long-term service life.
