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

Part Number: RS55261

Summary: The Rancho RS5000X series leverages advanced Cross-Tuned technology to provide a significant upgrade in ride quality for your Ford F-350. Engineered specifically for vehicles with a 4-inch rear lift, these gas-pressurized twin-tube shocks excel at absorbing harsh impacts while maintaining consistent control during heavy-duty hauling. The unique valving system reduces aeration and shock fade, ensuring your heavy-duty truck remains composed on both washboard roads and smooth highways.

Features

• Cross-Tuned Technology: A unique valving system provides a progressive engagement of the valving to ensure a smooth transition between highway comfort and off-road control.
• Twin-Tube Gas Pressure: The nitrogen-charged twin-tube design provides a protective outer shell for the inner working cylinder to ensure maximum durability against rock chips and trail debris.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides increased structural rigidity to ensure long-term seal integrity in demanding environments.
• Polyurethane Bushings: High-density mounting points provide enhanced vibration dampening to ensure a quiet, rattle-free cabin experience.

Frequently Asked Questions

Will these shocks lift my Ford F-350?
No, these shocks do not create lift. They are specifically valved and sized to function on vehicles already equipped with a 4-inch rear lift kit.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55261) includes two rear shocks to complete the installation for both sides of the rear axle.

What is the benefit of the twin-tube design for an F-350?
The twin-tube design is highly durable for work trucks; if the outer body is dented by road debris, the inner cylinder remains functional, ensuring you aren’t left stranded.
