Rancho RS9000XL 2.5″ Lift Shocks for 2017-2025 Ford F-250/F-350 4WD

Part Number: RS999043 / RS999047A

Summary: The Rancho RS9000XL series provides industry-leading adjustability for heavy-duty Ford trucks, featuring a 9-position manual tuning knob to customize ride quality on the fly. This complete set is engineered to accommodate a 2.5-inch lift, allowing drivers to transition from soft street comfort to firm control for heavy towing or off-road use. By providing individual control over damping levels, these shocks solve the common issue of a “one size fits all” suspension feel in versatile work and play vehicles.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides 400% change in damping force to ensure the driver can optimize ride quality for various loads and terrains.
• Large Diameter Shock Body: A 2.75-in. (70mm) reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty hauling.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a barrier between the oil and gas to ensure consistent performance by preventing aeration and foaming.
• Polyurethane Bushings: High-performance polyurethane material provides enhanced durability and reduced deflection to ensure precise handling under load.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a 9-position knob located at the base of the shock body. Simply turn the dial to “1” for the softest ride or “9” for maximum firmness and control.

Will these shocks fit a stock height truck?
These specific part numbers are configured for vehicles with a 2.5-inch lift kit installed and may not be suitable for stock height applications.

Do these shocks help with towing stability?
Yes, by increasing the damping setting via the adjustment knob, you can significantly reduce sway and “porpoising” when carrying heavy tongue weights or payloads.
