Summary: The Rancho RS9000XL series provides industry-leading adjustability for Jeep Wrangler JK owners seeking total control over their ride quality. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street feel to a firm setting for heavy towing or aggressive off-road crawling. Engineered for vehicles with 4 inches of rear lift, they offer the versatility needed to handle varying payloads and terrain types without compromising comfort.

Features

• MyRide Tuning System: A 9-position manual adjustment knob provides nine levels of damping control to ensure the perfect ride for any load or road condition.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent damping during long-distance hauling.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure immediate response and fade-free performance.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against trail debris.

Frequently Asked Questions

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

Will these shocks lift my Jeep Wrangler JK?
No, these shocks do not provide lift. They are specifically engineered with the correct extended and compressed lengths to function on a Jeep Wrangler JK already equipped with a 4-inch lift kit.

What is the benefit of the larger 2.75-inch body?
The increased diameter allows for a larger oil reservoir, which helps dissipate heat more efficiently than standard shocks, preventing performance fade during heavy-duty use.
