Summary: The Rancho RS9000XL series provides industry-leading versatility for classic Jeep and AM General applications. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to suit specific cargo loads or terrain requirements. This Tier 2 adjustable technology solves the compromise between street comfort and off-road stability, offering a custom-tailored ride for 2.5-inch lifted configurations.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine distinct levels of damping force to ensure the perfect ride for towing, hauling, or daily driving.
• Large Shock Body: A massive 2.75-inch diameter reserve tube provides increased fluid capacity to ensure consistent performance and reduced fade under heavy use.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road imperfections to ensure tire-to-ground contact is maintained.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position knob located at the base of the shock body. Simply turn the dial to your desired setting; 1 is the softest and 9 is the firmest.

Will these shocks lift my Jeep?
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 2.5-inch lift kit.

What is the benefit of the large 2.75-inch body?
The larger body houses more oil, which helps dissipate heat more effectively than smaller shocks, preventing “shock fade” during prolonged use on rough roads.
