Part Number: RS999119

Summary: The Rancho RS9000XL series delivers industry-leading versatility for classic Jeep and AM General platforms. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile from soft street cruising to firm control for towing or off-road use. Engineered for vehicles with 0-1.5 inches of lift, they provide a custom-tailored ride quality that adapts to your specific driving environment.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect balance between comfort and performance.
• Large Diameter Body: A 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operation during sustained cycling.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent damping response.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the oil seal and piston rod to ensure long-term durability in harsh environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The shocks feature 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 Scrambler?
No, these shocks do not create lift. They are specifically valved and clearanced for vehicles that already have 0 to 1.5 inches of lift height installed.

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 efficiently and prevents “shock fade” during heavy use.
