Summary: The Rancho RS9000XL series is the industry benchmark for user-adjustable damping control, specifically engineered for heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow owners of the Ford F-450 Cab & Chassis to transition seamlessly between a comfortable highway ride and the firm damping required for heavy towing or hauling. This versatility ensures that your vehicle maintains stability and comfort regardless of the payload or terrain.

Features

• 9-Position Manual Dial: A multi-stage damping adjustment provides nine levels of control to ensure the perfect ride quality for street, towing, or off-road use.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a faster response time and minimizes aeration to ensure consistent performance under heavy loads.
• Tri-Tube Design: A robust internal construction provides increased fluid capacity to ensure lower operating temperatures during demanding work cycles.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

How do I adjust the firmness 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 preferred setting—1 for softest and 9 for firmest.

Will these shocks lift my Ford F-450?
No, these shocks are configured for a 0-inch lift and are designed to replace factory-length shocks without changing the vehicle’s ride height.

Can I use these shocks if I carry a heavy service body or trailer?
Yes, the adjustable nature of the RS9000XL makes them ideal for Cab & Chassis models, as you can increase the damping to manage the extra weight and reduce body roll.
