Rancho RS9000XL 5-6″ Rear Lift Shocks for 1999-2006 Chevy Silverado 1500 4WD

Part Number: RS994297

Summary: The Rancho RS9000XL series is the industry benchmark for adjustable damping control, specifically engineered for heavy-duty applications and lifted geometries. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly adjust ride firmware to compensate for varying payloads or off-road conditions. This Tier 2 adjustable system provides the versatility required to maintain street comfort while providing the necessary damping force for 5-6 inch lifted rear suspensions.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure the perfect balance between highway comfort and towing stability.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent valving performance during aggressive suspension cycling.
• Large Shock Body: A heavy-duty 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during long-haul use.
• Polyurethane Bushings: High-density polyurethane material provides reduced deflection and improved durability to ensure precise axle control.

Frequently Asked Questions

Do these shocks create the 5-6 inches of lift?
No, these shocks are specifically length-tuned for vehicles that already have a 5-6 inch rear lift kit installed. They do not provide the lift itself.

How do I adjust the firmness of the ride?
Each shock features a manual 9-position knob at the base of the body. Simply turn the dial to a lower number for a softer ride or a higher number for increased firmness.

What is the benefit of the larger shock body?
The oversized 2.75-inch body holds more oil than standard shocks, which dissipates heat more effectively to prevent “shock fade” during heavy use or off-roading.
