Part Number: RS999042

Summary: The Rancho RS9000XL series is the industry leader in adjustable damping, specifically engineered to handle the heavy-duty demands of the Ford F-550. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition between a soft street ride and the firm control required for heavy towing or hauling. Designed for stock height applications, they provide a custom-tailored suspension response that adapts to your specific payload and terrain requirements.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the perfect balance between ride comfort and loaded stability.
• Large 2.75-inch Body: An increased fluid capacity housing provides superior heat dissipation to ensure consistent performance during heavy-duty cycles.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Protective Boot: A heavy-duty liquid metallic finish and included boot provide protection against road debris and corrosion to ensure long-term durability.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features an easy-to-reach 9-position knob 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-550?
No, these shocks are configured for 0-inches of lift and are designed to replace the factory-length dampers at stock ride height.

What is the benefit of the large 2.75-inch body?
The larger body holds more oil, which keeps the internal valving cooler under the extreme loads typical of an F-550, preventing the “fading” feeling during long trips.
