Rancho RS9000XL 0″ Front Lift Shocks for 2017-2020 Ford F-450 / F-550

Part Number: RS999042

Summary: The Rancho RS9000XL series provides industry-leading versatility for heavy-duty work trucks through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow owners of Ford Cab & Chassis models to instantly transition from a soft street ride to a firm setting for heavy hauling or towing. Engineered to handle the extreme demands of the F-450 and F-550 platforms, these shocks provide a custom-tailored ride quality that standard fixed-rate shocks cannot match.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect balance between comfort and stability for varying load weights.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas integration provides immediate response to road imperfections to ensure consistent tire-to-road contact.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity in harsh environments.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
These shocks feature a manual 9-position knob located at the base of the shock body. Simply turn the dial to a lower number for a softer ride or a higher number for increased firmness during towing.

Will these shocks lift my Ford F-450?
No, these shocks are configured for 0-inch lift and are designed to replace the factory-length dampers while maintaining the original ride height.

What is the benefit of the larger 2.75-inch body?
The increased oil capacity allows the shock to dissipate heat more effectively, which prevents “shock fade” and maintains consistent performance when driving on rough terrain or carrying heavy loads.
