The Rancho RS5000X series front shock absorber (MPN: RS55237) is engineered to deliver improved handling and ride quality for Ford light-duty trucks and SUVs. Utilizing exclusive Cross Tuned technology and Progressive Engagement Valving, these shocks are custom-tuned for each application to reduce initial impacts at low speeds while maintaining control during aggressive maneuvers. The twin-tube design features a large body filled with all-weather fluid, capable of withstanding internal temperatures from -40 to 248°F, ensuring consistent performance in extreme environments.

• Precision Valving: Progressive Engagement Valving minimizes rough ride by regulating fluid transfer without disc flutter.
• Durable Construction: Features a 16mm nitro-carburized piston rod for corrosion resistance and double-welded loops at stress points.
• Gas Pressurized: Nitrogen gas charged to 150 PSI to minimize air-to-oil mixture, reducing damping fade and foaming.
• Robust Internals: 35mm sintered iron piston provides structural integrity and an expanded piston area for heightened motion control.
• Protection: Includes a polyvinyl protective boot to shield the rod and seal from debris.
