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

Part Number: RS999056

Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty applications by featuring a 9-position manual adjustment knob. This Tier 2 adjustable system allows drivers to instantly transition between a soft street ride and a firm setting for heavy towing or off-road stability. Engineered to accommodate 5 to 6 inches of rear lift, these shocks provide the necessary travel and damping control to manage the increased center of gravity on lifted Chevy and Hummer platforms.

Features

• MyRide Tuning System: A 9-position manual adjustment knob provides custom damping control to ensure optimal ride quality across varying load conditions.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure consistent performance and reduced fade during high-temp operation.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road irregularities to ensure tire-to-ground contact is maintained.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.

• Performance Benefit: Drivers gain the ability to “dial in” their suspension, eliminating the compromise between a comfortable daily commute and the stiffness required for hauling heavy trailers.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a 9-position manual knob located at the base of the shock body; simply turn the dial to increase or decrease damping resistance.

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles that already have 5 to 6 inches of rear lift installed.

What is the benefit of the larger 2.75-inch body?
The larger body houses more oil, which helps dissipate heat more efficiently than standard shocks, preventing “shock fade” during strenuous use.
