Rancho RS5000X 4″ Rear Lift Shocks for 1997-2003 Ford F-150 4WD

Part Number: RS55238

Summary: The Rancho RS5000X series leverages a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted Ford F-150 applications. Configured for 4-inch rear lift heights, these shocks utilize a unique Progressive Engagement Valving system to minimize harshness during initial impacts. This design ensures consistent damping and durability for daily driving and light trail use, effectively managing the increased unsprung weight of larger tire and wheel combinations.

Features

• Progressive Engagement Valving: Custom-tuned internal valving provides a smoother transition between low and high-speed damping to ensure controlled ride quality over varied terrain.
• Twin-Tube Gas Pressure: The nitrogen-charged twin-tube body provides a secondary fluid path for heat dissipation to ensure consistent performance during repeated cycling.
• 12.21-inch Travel: An extended stroke length provides increased articulation capacity to ensure the rear suspension remains active and engaged during off-road maneuvers.
• Protective Boot: A high-quality polyvinyl accordion boot provides a physical barrier against debris and road salt to ensure the longevity of the polished piston rod.

Frequently Asked Questions

Will these shocks lift my truck by 4 inches?
No, these shocks do not create lift. They are specifically sized and valved to work on a vehicle that has already been equipped with a 4-inch rear lift kit.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable for off-road use; if the outer tube is dented by a rock, the inner tube remains functional, allowing the shock to continue operating.

Do these come with the mounting hardware?
Yes, these shocks include the necessary bushings and hardware to facilitate a direct replacement of the factory units on compatible lift setups.
