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

Part Number: RS55287

Summary: The Rancho RS5000X series utilizes a patented Progressive Engagement Valving system to provide a smooth, comfortable ride for your Ford F-150. Specifically configured for 4.5-inch rear lift heights, these shocks are designed to handle the increased demands of lifted applications while maintaining daily-driver durability. The twin-tube gas pressurized design ensures consistent performance and dent resistance, making it an ideal solution for truck owners seeking a balance between highway comfort and off-road capability.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between low and high-speed damping to ensure controlled handling across varied terrain.
• Nitrogen Gas Pressurization: A 150 PSI gas charge provides a consistent barrier between the oil and gas to ensure reduced aeration and shock fade.
• Twin-Tube Body: A 2.25-inch diameter outer reserve tube provides increased oil capacity and physical protection to ensure the internal piston remains functional even if the outer shell is dented.
• All-Weather Fluid: Specialized synthetic oil contains friction modifiers to ensure smooth rod stroke and consistent performance in extreme temperature fluctuations.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically long-travel dampers configured for vehicles that already have a 4.5-inch rear lift kit installed.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55287) includes a pair of two (2) shocks for the rear of your vehicle.

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