Rancho RS5000X 4.5″ Lift Shocks for 2015-2019 Ford F-150 4WD

Part Number: RS55838 (Kit SKU: 2xRS55838_2xRS55287_n390)

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to enhance the ride quality of your lifted Ford F-150. Specifically configured for 4.5-inch lift heights, these shocks feature a unique progressive engagement valving system that minimizes harshness during initial impacts. This Tier 4 setup is engineered for maximum durability and dent resistance, providing a smooth, controlled street feel while maintaining the ruggedness required for off-road excursions.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping circuits to ensure a smooth ride over small road imperfections.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and aeration to ensure consistent damping performance under heavy use.
• Enlarged 2.25-inch Body: A larger fluid capacity provides increased heat dissipation to ensure stable shock performance during extended driving cycles.
• Protective Boot: Included heavy-duty poly-vinyl bellows provide a physical barrier for the shock rod to ensure seal longevity against debris and corrosion.

Frequently Asked Questions

Will these shocks lift my Ford F-150?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 4.5-inch suspension lift kit to ensure proper travel and performance.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable; if the outer body is dented by a rock or debris, the inner cylinder remains unaffected, allowing the shock to continue functioning correctly.

Are the shock boots required for installation?
While the shocks will function without them, the included boots are highly recommended to protect the piston rod from pitting and to extend the life of the pressure seals.
