Rancho RS5000X Front Shock Absorber - Select Ford & International 1966-1996 (RS55117)

Fits select 1966-1996 Ford Bronco, F-100/F-150/F-250, E-100/E-150, and Ranger, as well as 1971-1980 International Scout and Travelall models.

The Rancho RS5000X is a twin-tube gas-pressurized shock absorber engineered to deliver a refined ride on and off-road. Featuring exclusive Progressive Engagement Valving, the RS55117 is custom-tuned to minimize initial impacts at low speeds while maintaining firm control during high-speed compression. The nitrogen gas charge, pressurized to 150 PSI, significantly reduces aeration and damping fade, ensuring consistent performance even under heavy articulation.

• Durable Construction: Features a 16mm nitro-carburized piston rod for superior scuff and corrosion resistance, plus double-welded loops at high-stress points.
• Thermal Stability: The large twin-tube body is filled with all-weather fluid designed to withstand internal operating temperatures ranging from -40 to 248°F.
• Smooth Operation: A 35mm sintered iron piston and fluon-banded seal enhance responsiveness, while a polyurethane rebound bumper and rubber bushings help isolate road harshness.
• Complete Protection: Each shock includes a polyvinyl protective boot to safeguard the rod and seal from debris.
