Rancho RS5000X Rear Shock Absorber for 1997-2002 Ford Expedition (RS55246)

Fits 1997-2002 Ford Expedition Eddie Bauer and XLT models. This Rancho RS5000X series rear shock (MPN: RS55246) is engineered for drivers who demand a balance between on-road comfort and off-road durability.

The RS5000X utilizes Rancho's exclusive Cross Tuned technology, featuring a unique rebound valving system and Progressive Engagement Valving (PEV). This setup allows the shock to minimize initial impacts at low speeds while providing increased control during aggressive maneuvers or rough terrain. The twin-tube body is pressurized with nitrogen gas to 150 PSI, significantly reducing aeration and shock fade during heavy use. Built to withstand extreme conditions, the unit is rated for internal temperatures ranging from -40 to 248°F.

• Durable Construction: Features a 16mm nitro-carburized piston rod to resist scuffs and corrosion, and double-welded loops at high-stress points.
• Precision Valving: Includes a 35mm sintered iron piston and a custom-tuned Compression Control Valve for consistent fluid transfer.
• Ride Quality: Polyurethane rebound bumpers and rubber bushings absorb harsh road vibrations, while the fluon-banded piston provides a smooth, responsive seal.
• Protection: Includes a polyvinyl protective boot to shield the piston rod and oil seal from debris.
• Specifications: Part Number RS55246; 35mm piston diameter; 16mm rod diameter; 150 PSI nitrogen charged.
