Summary: The Rancho RS9000XL series provides the ultimate in ride control for the 1987-1996 Ford F-250 and F-350 4WD. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow owners to instantly tune their damping profile from soft to firm to suit specific hauling or off-road needs. Engineered for vehicles with a 4-inch lift, this set ensures your heavy-duty Ford maintains optimal tire-to-road contact and stability regardless of the terrain.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can transition from a comfortable street ride to firm control for heavy towing.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during extreme use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent valving performance.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the oil seal to ensure long-term durability against road debris.

Frequently Asked Questions

How do I adjust the stiffness of these shocks?
The RS9000XL features a 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 Ford F-250?
No, these shocks do not create lift. They are specifically valved and extended to accommodate a Ford F-250 or F-350 that already has a 4-inch suspension lift installed.

Are these shocks nitrogen charged?
Yes, they are nitrogen gas pressurized to minimize oil foaming and ensure rapid response during high-frequency cycling.
