Rancho RS5000X 4″ Lift Shocks for 2004-2008 Ford F-150 4WD

Part Number: RS55769

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in durability and ride quality for lifted applications. Utilizing a sophisticated twin-tube design with Cross-Tune Technology, these shocks manage the increased unsprung weight of larger wheel and tire combinations common on 4-inch lifts. This configuration ensures a smooth, controlled street ride while maintaining the ruggedness required for off-road environments.

Features

• Cross-Tune Technology: Progressive engagement valving provides a custom-tuned damping curve to ensure consistent comfort across varying terrain.
• Gas Pressurization: Low-pressure nitrogen charge provides a reduction in aeration and foaming to ensure fade-free performance during spirited driving.
• Heavy-Duty Body: A 2.25-inch reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.

Frequently Asked Questions

Will these shocks lift my truck 4 inches?
No, these shocks do not create lift. They are specifically valved and extended to accommodate a truck that already has a 4-inch suspension lift installed.

Are these shocks sold as a complete set?
Yes, this SKU includes all four shocks required for the front and rear of the vehicle to match a 4-inch lift height.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is exceptionally durable; even if the outer body is dented by a rock or debris, the inner working cylinder remains protected, ensuring you aren’t stranded on the trail.
