The Rancho RS5000X series (RS55272) is a heavy-duty, gas-pressurized twin-tube shock absorber designed to bridge the gap between street comfort and off-road control. Built with Rancho’s exclusive Cross Tuned technology, these shocks feature a unique rebound valving system and advanced compression phase that significantly improves vehicle handling. The Progressive Engagement Valving is specifically tuned for Ford suspension geometry to reduce initial impact harshness at low speeds while maintaining firm control on rough terrain.

• Robust Construction: Features a 16mm nitro-carburized piston rod for superior scuff and corrosion resistance and a 35mm sintered iron piston for structural integrity.
• Advanced Valving: Nitrogen gas pressurized to 150 PSI to minimize oil foaming and damping fade during high-cycle operation.
• Temperature Resistance: Large twin-tube body filled with all-weather fluid capable of withstanding internal temperatures from -40°F to 248°F.
• Refined Ride: Polyurethane rebound bumpers and rubber bushings absorb harsh road vibrations, while the fluon-banded piston ensures consistent responsiveness.
• Installation Protection: Includes a polyvinyl protective boot to shield the seal and piston rod from road debris and moisture.
