Rancho RS5000X 2.5″ Rear Lift Shocks for 2011-2016 Ford F-350 4WD

Part Number: RS55254

Summary: The Rancho RS5000X series features an innovative Cross-Tuned technology system that utilizes a unique progressive engagement valving design. Engineered for the Ford F-350, these twin-tube gas pressurized shocks provide exceptional durability and impact absorption for both highway transit and rugged work sites. By minimizing fluid aeration and shock fade, this setup delivers a smooth, controlled ride that compensates for the increased demands of a 2.5-inch rear lift.

Features

• Cross-Tuned Technology: A progressive engagement valving system provides custom-tuned damping to ensure superior control during high-velocity impacts.
• Gas Pressurized Twin-Tube: High-pressure nitrogen gas charge provides reduced aeration and foaming to ensure consistent performance under heavy loads.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural rigidity to ensure long-term resistance against scuffs and corrosion.
• Protective Boot: A durable polyvinyl accordion boot provides a physical barrier for the oil seal to ensure debris does not compromise the internal valving.

Frequently Asked Questions

Will these shocks lift my Ford F-350?
No, these shocks do not create lift. They are specifically lengthened and valved to accommodate a vehicle that has already been equipped with 2.5 inches of rear lift height.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable for work trucks; even if the outer tube is dented by a rock or debris, the inner cylinder remains protected, allowing the shock to continue functioning.

Does this fit the Chassis Cab (Dually) models?
No, these specific units are excluded from use on Chassis Cab models and are intended for standard pickup bed configurations.
