Rancho RS9000XL 4″ Rear Lift Shocks for 1981-1993 Ford Bronco 4WD

Part Number: RS999118

Summary: The Rancho RS9000XL series provides industry-leading adjustability for drivers who demand versatility from their 4WD vehicle. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy towing or aggressive off-road use. Engineered to accommodate a 4-inch rear lift, these shocks solve the compromise between daily comfort and heavy-duty performance by putting damping control directly in the user’s hands.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the vehicle is perfectly tuned for specific loads or terrain.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during long-distance hauling.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road imperfections to ensure consistent tire-to-ground contact.
• Protective Boot: A heavy-duty red 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 stiffness of these shocks?
These shocks feature a 9-position knob located at the base of the shock body. Simply turn the dial to “1” for the softest ride or up to “9” for maximum firmness.

Will these shocks provide my vehicle with 4 inches of lift?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles that have already been modified with a 4-inch lift kit.

Do I need special tools to install the RS9000XL?
No, these are designed as a direct bolt-on replacement for the factory units using standard hand tools and the provided hardware.
