Rancho RS9000XL 2.5″ Rear Lift Shocks for 2011-2016 Ford F-350 4WD

Part Number: RS999254

Summary: The Rancho RS9000XL series delivers professional-grade ride control for the Ford F-350, featuring a globally recognized 9-position manual adjustment system. This Tier 2 adjustable shock allows drivers to instantly switch between a soft street ride and a firm setting for heavy towing or high-payload hauling. Designed specifically for F-350s with a 2.5-inch rear lift, these shocks provide the versatility needed to manage the transition from daily commuting to demanding work site conditions.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the vehicle is perfectly tuned for specific loads or terrain.
• Large Shock Body: The 2.75-inch diameter reserve tube provides increased fluid capacity to ensure lower operating temperatures during heavy-duty towing.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a consistent response and minimizes aeration to ensure fade-free performance.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure longevity against road debris and corrosion.

Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features an external 9-position knob located at the base of the shock, allowing you to manually click through settings from soft (1) to firm (9) without tools.

Will these shocks lift my Ford F-350?
No, these shocks do not create lift. They are specifically engineered with the correct extended and compressed lengths to function on a vehicle already equipped with a 2.5-inch rear lift kit.

What is the benefit of the larger 2.75-inch body?
The larger body houses more oil, which acts as a heat sink. This keeps the internal valving cooler during repetitive cycling, preventing the “fade” or softening of the shock during heavy use.
