Rancho RS5000X 4″ Lift Shocks for 2005-2016 Ford F-250 4WD

Part Number: RS55044 / RS55261

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to enhance the ride quality of your lifted Ford F-250. Engineered specifically for vehicles with a 4-inch lift, these shocks feature a unique valving system that minimizes harshness while maintaining firm control during off-road excursions. The gas-pressurized construction provides consistent damping and durability, making it an ideal solution for drivers seeking a balance between daily street comfort and rugged work-site performance.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides increased control at higher speeds to ensure stability during aggressive maneuvers.
• Twin-Tube Gas Pressure: The 150-PSI nitrogen gas charge reduces aeration and foaming to ensure consistent damping performance in varied temperatures.
• Large 2.25-inch Body: An increased fluid capacity housing provides better heat dissipation to ensure long-term durability under heavy loads.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior scuff and corrosion resistance to ensure a long service life in harsh environments.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and extended to accommodate Ford F-250/F-350 models already equipped with a 4-inch suspension lift.

Are these shocks compatible with Dually models?
No, these are designed for Single Rear Wheel (SRW) configurations and are not compatible with Chassis Cab or Dual Rear Wheel models.

What is the benefit of the included shock boots?
The protective boots shield the nitro-carburized piston rod from rocks, dirt, and debris, which helps prevent seal damage and leaks.
