Rancho 97-02 Ford Expedition Front RS5000X Shock

Rancho RS5000X front shock absorber, part number RS55372, is built for your 1997-2003 Ford F-150, 1997-2002 Ford Expedition, 2004 Ford F-150 Heritage, or 1997-1999 Ford F-250. This shock absorber is designed to give you better control and a smoother ride, whether you're on the pavement or hitting the trail. It uses a unique valving system that adjusts to changing conditions, helping to absorb impacts effectively and reduce harshness.

The construction of this shock is solid, featuring a 16mm nitro-carburized piston rod that resists scuffs and corrosion, along with double-welded loops for extra strength in high-stress areas. Its large twin-tube body is filled with an all-weather fluid that keeps it operating cooler, even in extreme temperatures from -40 to 248°F, which helps maintain consistent performance and vehicle control. A fluon-banded piston and polyurethane rebound bumper work together to absorb road imperfections and enhance responsiveness, making for a more comfortable ride.

This shock also includes a nitrogen gas charge of 150 PSI to prevent air from mixing with the oil, which helps reduce damping fade and foaming during heavy use. The Compression Control Valve is specifically tuned for your vehicle to manage fluid transfer and maintain shock motion control, ensuring you have reliable handling.
