Rancho RS5000X 4″ Front Lift Shocks for 2009-2013 Ford F-150 4WD

Part Number: RS55806

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted Ford F-150 applications. Engineered specifically to manage the increased unsprung weight of larger wheel and tire packages, these shocks feature a unique progressive engagement valving system. This setup delivers a smooth, comfortable street ride while maintaining the durability and dent resistance required for demanding off-road environments.

Features

• Cross-Tuned Technology: A specialized valve base provides a custom-tuned compression and rebound cycle to ensure consistent handling on varied terrain.
• Progressive Engagement Valving: Custom-tuned internal discs provide a soft initial response that firms up under heavy loads to ensure maximum control during aggressive maneuvers.
• Gas Pressurized Twin-Tube: A nitrogen gas charge provides a consistent dampening force to ensure reduced aeration and shock fade during extended use.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.

Frequently Asked Questions

Will these shocks lift my Ford F-150?
No, these shocks do not create lift. They are extended-length shocks configured for vehicles already equipped with a 4-inch lift kit.

What is the benefit of the Twin-Tube design on this model?
The twin-tube design is exceptionally durable; the outer tube can take a dent from a rock or debris without affecting the inner cylinder or piston travel.

Do these come with the red boots pictured?
Yes, these RS5000X shocks include the signature Rancho red polyvinyl boots to protect the shock rod from contaminants.
