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

Part Number: RS999044 / RS999261

Summary: The Rancho RS9000XL series provides industry-leading adjustability for Ford Super Duty owners who demand versatility from their suspension. Featuring a globally recognized 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 off-road excursions. Engineered to accommodate a 4-inch lift, this set ensures your leveled or lifted F-250/F-350 maintains peak damping control regardless of payload or terrain.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure custom-tailored ride control for towing, hauling, or daily driving.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a consistent response by minimizing aeration and foaming to ensure stable performance in extreme conditions.
• Protective Boot: A heavy-duty liquid metallic finish and included poly-vinyl accordion boot provide a physical barrier against road debris to ensure long-term seal integrity.

Why Choose This Product?

• Engineering Advantage: Unlike “one-size-fits-all” shocks, the RS9000XL utilizes a tri-tube design and adjustable valving that allows the user to override the factory damping profile based on real-time needs.
• Performance Benefit: Drivers experience a significant reduction in body roll and “float” when towing, with the ability to soften the suspension for a comfortable, car-like commute when the truck is unladen.

Frequently Asked Questions

How do I adjust the settings on 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 firmness level—no tools required.

Will these shocks lift my Ford F-250?
No, these shocks do not create lift. They are specifically valved and extended in length to function correctly on vehicles already equipped with a 4-inch suspension lift kit.

Can these be used on a Dually (DRW) or Chassis Cab?
According to the fitment specifications, these are designed for Single Rear Wheel (SRW) models and are not compatible with Chassis Cab configurations.
