Rancho RS90000XL 5-6″ Rear Lift Shocks for 2001-2003 Chevy Silverado 1500HD 4WD

Part Number: RS999056

Summary: The Rancho RS90000XL series provides industry-leading adjustability for drivers who demand total control over their vehicle’s ride profile. Featuring a 9-position manual tuning knob, these shocks allow you to instantly switch between a soft street ride and a firm setting for heavy towing or high-speed off-road handling. Engineered to accommodate 5-6 inches of rear lift, they provide the necessary travel to maintain contact with the terrain while eliminating the harsh bottoming-out common in lifted applications.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect balance between comfort and performance for any load or terrain.
• Large Diameter Body: A 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operating temperatures during extreme use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a consistent response and prevents aeration to ensure fade-free performance.
• Protective Boot: A durable liquid-metallic finish and included poly-vinyl boot provide superior protection for the piston rod to ensure long-term seal integrity.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS90000XL features a 9-position knob at the base of the shock body. Turning the knob allows you to manually increase or decrease the damping resistance without tools.

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to work with vehicles already equipped with a 5-6 inch rear lift kit.

What is the benefit of the larger shock body?
The 2.75-inch body holds more oil than standard shocks, which helps dissipate heat more effectively, preventing the “vague” feeling known as shock fade during heavy use.
