Fits 1983-2011 Ford Ranger (All trims including XL, XLT, Sport, STX, and FX4).

The Rancho RS5000X series shock absorber utilizes advanced Cross Tuned technology to deliver a significant upgrade in handling and control for your Ford Ranger. Designed for both on-road stability and off-road durability, this twin-tube shock features an exclusive Progressive Engagement Valving system. This system is custom-tuned to reduce initial impacts at low speeds while maintaining firm control during high-speed maneuvers, effectively minimizing ride harshness across varied terrain.

Built to withstand extreme conditions, the RS55126 is nitrogen gas-pressurized to 150 PSI to minimize aeration and foaming, ensuring consistent damping performance even during heavy use. The 16mm nitro-carburized piston rod provides superior resistance to scuffs and corrosion, while the 35mm sintered iron piston adds structural integrity to the internal assembly. Every shock is finished with a protective polyvinyl boot to shield the rod and seal from debris.
