Summary: The Rancho RS9000XL series delivers industry-leading versatility for classic Ford Bronco and FJ-9 applications. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow drivers to instantly tune damping levels to suit specific cargo loads or terrain requirements. Whether you are seeking a soft street ride or firm control for towing and hauling, this nitrogen-gas pressurized shock provides the precise damping profile needed for vintage 4WD stability.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure custom-tailored ride control for any environment.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in oil foaming and aeration to ensure consistent performance under high-cycle conditions.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures during extended use.
• Protective Boot: A durable polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

How do I adjust the stiffness of these shocks?
These shocks feature a 9-position manual knob located at the base of the shock body. Simply turn the dial to your desired setting, from 1 (softest) to 9 (firmest).

Are these shocks compatible with lifted vehicles?
These specific shocks are configured for 0″ of rear lift (stock height) and should only be used on vehicles within that height range to maintain proper travel.
