Rancho RS9000XL 4″ Rear Lift Shocks for 2002-2006 Chevy Avalanche 1500 4WD

Part Number: RS999274

Summary: The Rancho RS9000XL series provides industry-leading adjustability for drivers who demand total control over their suspension damping. Featuring a 9-position manual tuning knob, these rear shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered to accommodate a 4-inch lift, they deliver the necessary travel and damping force to maintain tire contact and ride quality on lifted Chevy and GMC platforms.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the vehicle is perfectly calibrated for daily driving, hauling, or trail use.
• Large Diameter Body: A 2.75-inch heavy-duty shock body provides increased fluid capacity to ensure cooler operating temperatures during high-demand cycles.
• Nitrogen Gas Charged: High-pressure gas displacement provides immediate response and prevents oil foaming to ensure consistent performance across varied terrain.
• Protective Boot: A durable polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a 9-position knob located at the base of the shock body. Simply turn the dial to your preferred setting: 1 for the softest ride and 9 for maximum firmness.

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to work with a vehicle already equipped with a 4-inch rear lift kit.

Can I use these on a stock height vehicle?
No, these shocks are designed for vehicles with 4 inches of rear lift. Installing them on a stock height vehicle may result in the shock bottoming out, causing internal damage.
