Rancho RS9000XL 4″ Rear Lift Shocks for 2002-2006 Chevy Avalanche 2500 & Hummer H2

Part Number: RS994297

Summary: The Rancho RS9000XL series provides the ultimate in ride control versatility for heavy-duty SUVs. Featuring a 9-position manual tuning knob, these shocks allow owners to instantly adjust damping levels to compensate for varying payloads or off-road conditions. Engineered for vehicles with 4 inches of rear lift, they provide a custom-tuned solution that bridges the gap between highway comfort and aggressive trail performance.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect ride for towing, hauling, or daily commuting.
• Large Diameter Body: A 2.75-in. reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance in demanding environments.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a shield for the shock rod to ensure long-term seal integrity against debris.
