Rancho RS9000XL 5-6″ Lift Shocks for 2002-2006 Chevy Avalanche 2500 4WD

Part Number: RS999055

Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty applications and lifted builds. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow owners to instantly tune damping levels to compensate for varying payloads or terrain changes. Whether you are navigating a daily commute or hauling a heavy trailer, this system provides the specific valving required to maintain vehicle control and ride quality.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the ride can be softened for street use or firmed for heavy towing.
• Large Diameter Body: A 2.75-inch heavy-duty body provides increased fluid capacity to ensure lower operating temperatures during demanding off-road use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a consistent response by minimizing aeration to ensure fade-free performance.
• Protective Boot: A durable liquid metallic finish and included shock boot provide a secondary layer of protection for the piston rod to ensure long-term seal integrity.
