Rancho RS5000X 4″ Rear Lift Shocks for 2005-2010 Ford F-350 4WD Single Rear Wheel

Part Number: RS55045

Summary: The Rancho RS5000X Series gas-pressurized shock absorbers provide a significant upgrade in ride quality and durability for your Ford F-350. Engineered to handle the increased demands of a 4-inch rear lift, these shocks utilize a unique cross-tuned valve system to manage the high unsprung weight of heavy-duty trucks. This twin-tube design is specifically optimized to provide smooth street comfort while maintaining the rugged dent resistance required for off-road environments and work sites.

Features

• Cross-Tuned Technology: A specialized progressive engagement valving system provides customized damping levels to ensure controlled handling during both low-velocity and high-velocity impacts.
• Gas-Pressurized Twin-Tube Design: The 150-PSI nitrogen gas charge provides a consistent oil-to-gas interface to ensure reduced aeration and shock fade during heavy towing or hauling.
• Protective Boot Included: A high-quality polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris and salt.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides increased tensile strength and corrosion resistance to ensure reliable performance in harsh climates.

Frequently Asked Questions

Do these shocks provide 4 inches of lift?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to work with a vehicle that already has a 4-inch rear lift kit installed.

Will these work on a Dually (DRW) model?
No, these are specifically designed for Single Rear Wheel (SRW) models and exclude Chassis Cab configurations.

What is the benefit of the Twin-Tube design on an F-350?
The twin-tube design offers an outer reserve tube that protects the inner working cylinder. If the outer body is dented by a rock or debris, the shock will continue to function, making it ideal for work trucks and off-road use.
