Rancho Suspension Shock Absorber P/N:RS55009

Smooth out the ride and keep your classic Ford truck planted on and off road with the Rancho RS5000X Suspension Shock Absorber RS55009. This is a REAR-position shock that drops in as a direct-fit replacement for the 1970-1979 Ford F-100, 1975-1979 Ford F-150, and 1970-1979 Ford F-250 — see the Buyer's Guide tab for engine-level details. Built around Rancho's exclusive Cross Tuned technology, it pairs a rebound valving system with an advanced compression phase to improve overall handling and performance.

• Cross Tuned technology: the rebound valving system and advanced compression phase are designed to improve on- and off-road handling.
• Progressive Engagement Valving: custom-tuned for the vehicle to help reduce initial low-speed impacts and minimize a rough ride.
• Strong and durable: 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.
• Temperature handling: large 2-1/4 in twin-tube body filled with all-weather fluid for cooler operation, nitrogen gas pressurized to 150 PSI to help reduce damping fade and foaming.

A polyurethane rebound bumper and rubber bushings help absorb ride harshness, and it's backed by Rancho's Limited Lifetime Warranty.
