Rancho RS9000XL 4″ Rear Lift Shocks for 2005-2016 Ford F-250/F-350 4WD

Part Number: RS999261

Summary: The Rancho RS9000XL series provides ultimate control for heavy-duty trucks through its globally recognized 9-position manual tuning system. By utilizing an adjustable knob, drivers can instantly transition from a soft street ride to a firm setting for heavy towing or off-road stability. These shocks are specifically configured for a 4-inch lift, ensuring the rear suspension maintains proper travel and damping performance on Ford Super Duty applications.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the vehicle is perfectly calibrated for daily driving, towing, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure nitrogen gas provides a consistent response and prevents aeration to ensure fade-free performance in demanding environments.
• Heavy-Duty Piston: A 1.25-inch sintered iron piston provides structural integrity and precise valving to ensure long-term durability on 4WD platforms.

Frequently Asked Questions

How do I adjust the stiffness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock body. Simply turn the dial to your desired setting; lower numbers for a softer ride and higher numbers for increased firmness.

Do these shocks provide a 4-inch lift?
No, these shocks do not create lift. They are specifically designed with the correct extended and compressed lengths to accommodate a vehicle that has already been equipped with a 4-inch rear lift kit.

What is the benefit of the large 2.75-inch body?
The oversized body allows for more oil and gas volume, which helps dissipate heat more efficiently than standard shocks, preventing the “fading” feeling during long trips or off-road use.
