Rancho RS90000XL 5″ Rear Lift Shocks for 2017-2020 Ford F-250 4WD

Part Number: RS999036

Summary: The Rancho RS9000XL series provides industry-leading adjustability for heavy-duty Ford F-250 applications. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered for trucks with a 5-inch rear lift, these shocks solve the compromise between daily comfort and work-ready performance.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure custom-tailored ride control for any load or terrain.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation during high-demand hauling.
• Nitrogen Gas Charging: Pressurized nitrogen gas provides resistance against oil foaming and aeration to ensure consistent damping performance.
• Heavy-Duty Piston: A 1.25-inch sintered iron piston provides structural integrity and increased surface area to ensure precise valving response.

Why Choose This Product?

• Engineering Advantage: Unlike standard fixed-rate shocks, the RS9000XL utilizes a tri-tube design and a manual dial that physically alters the internal bypass flow for true mechanical adjustment.
• Performance Benefit: Drivers gain the ability to eliminate “sag” feel and “body roll” when towing by simply turning the dial to a firmer setting, then returning to a plush ride for unloaded commuting.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position knob located at the base of the shock body. Turning the knob allows you to manually increase or decrease damping resistance without tools.

Will these shocks lift my Ford F-250?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on a Ford F-250 already equipped with a 5-inch rear lift kit.

Are the protective boots included?
Yes, these shocks include Rancho’s signature red protective boots to shield the piston rod from debris and corrosion.
