Rancho RS9000XL 4″ Rear Lift Shocks for 2007-2018 Jeep Wrangler JK

Part Number: RS999332

Summary: The Rancho RS9000XL series is the industry benchmark for adjustable damping, allowing Jeep Wrangler JK owners to bridge the gap between highway comfort and off-road control. Featuring a 9-position manual tuning knob, these shocks provide the versatility to soften the ride for daily commuting or firm it up for heavy towing and aggressive trail use. Engineered specifically for vehicles with a 4-inch rear lift, these shocks ensure your suspension maintains optimal travel and stability across diverse terrains.

Features

• 9-Position Tuning: A manual adjustment knob provides 400% change in damping force to ensure custom-tailored ride control for any load or terrain.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation during high-cycle off-road use.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to surface changes to ensure consistent damping performance.
• Protective Boot: A durable poly-vinyl accordion boot provides a shield for the piston rod to ensure long-term seal integrity and debris protection.

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 setting 1 for the softest ride or setting 9 for maximum firmness.

Will these shocks lift my Jeep Wrangler JK?
No, these shocks do not create lift. They are specifically valved and length-tuned to work with a Jeep Wrangler JK that already has a 4-inch rear lift kit installed.

What is the benefit of the large 2.75-inch body?
The larger body houses more oil, which helps dissipate heat faster than standard shocks, preventing “shock fade” during prolonged off-road driving.
