Rancho RS9000XL 5″ Lift Shocks for 2011-2016 Ford F-350 4WD

Part Number: RS999044 / RS999261

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the Ford F-350 Super Duty through its globally recognized adjustable damping technology. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road excursions. Specifically configured for 5-inch lifted applications, this set provides the necessary travel and damping control to manage the increased mass of larger wheel and tire combinations while maintaining OE-level comfort.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides nine levels of damping control to ensure the vehicle is perfectly tuned for daily driving, towing, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty hauling.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent damping performance under high-cycle stress.
• Polyurethane Bushings: Heavy-duty polyurethane material provides enhanced durability and reduced deflection to ensure precise steering response and road feel.

Frequently Asked Questions

How do I adjust the firmness of these shocks?
Each shock features a red 9-position knob at the base of the body. Turning the knob clockwise increases firmness, while counter-clockwise softens the damping.

Do these shocks create the 5-inch lift?
No, these shocks are specifically lengthened and valved for a vehicle that already has a 5-inch suspension lift installed. They do not provide the lift height themselves.

Will these fit a Dually (Dual Rear Wheel) F-350?
According to the fitment specifications, these are designed for Single Rear Wheel (SRW) models and exclude Chassis Cab configurations.
