Smooth out rough pavement and keep your truck composed on- and off-road with the Rancho RS5000X Suspension Shock Absorber RS55233, a front-position damper that installs as a direct-fit replacement for the 1997-2002 Ford Expedition, 1997-2003 Ford F-150, 2004 Ford F-150 Heritage, and 1997-1999 Ford F-250. See the Buyer's Guide tab for engine-level fitment.
- Cross Tuned technology: an exclusive rebound valving system and advanced compression phase engineered to improve overall handling and performance on and off road.
- Progressive Engagement Valving: custom-tuned per vehicle to help reduce initial impacts at low speeds and minimize a rough ride.
- Strong and durable build: 16mm nitro-carburized piston rod to resist scuffs and corrosion, double-welded loops at stress areas, a 35mm sintered iron piston, and a polyvinyl protective boot.
- Large twin-tube body: filled with all-weather fluid for cooler operation and rated to withstand internal temperatures of -40 to 248°F.
It runs a 2 1/4-inch twin-tube body nitrogen-pressurized to 150 PSI to minimize air-to-oil mixing and reduce damping fade and foaming, while a low-friction self-lubricating seal, polyurethane rebound bumper, and rubber bushings help absorb ride harshness. Backed by Rancho's Limited Lifetime Warranty.
