Fits select 1997-2004 Ford F-150 and F-150 Heritage models including XL, XLT, Lariat, King Ranch, and Harley-Davidson Edition.

The Rancho RS5000X (RS55236) is a twin-tube gas-pressurized shock designed to deliver improved handling and control for light trucks on and off the road. Utilizing Rancho's Cross Tuned technology, this shock features a unique rebound valving system and advanced compression phase to manage impact energy and reduce vehicle body roll. The 150 PSI nitrogen gas charge minimizes the air-to-oil mixture, effectively reducing damping performance fade and foaming during intensive use.

• Heavy-Duty Construction: Features a 16mm nitro-carburized piston rod to resist scuffs and corrosion, paired with a 35mm sintered iron piston for structural integrity.
• Progressive Engagement Valving: Custom-tuned per vehicle application to reduce initial impacts at low speeds for a smoother ride.
• Temperature Resistance: Large twin-tube body filled with all-weather fluid designed to operate in internal temperatures ranging from -40 to 248°F.
• Protective Design: Includes double-welded loops at stress areas, rubber bushings to absorb ride harshness, and a polyvinyl protective boot to shield the rod and seal from debris.
• Precision Sealing: Equipped with a low-friction, self-lubricating seal that retains gas and oil for consistent performance and quicker rebound.
