Rancho RS55048 RS5000X Gas-Charged Twin-Tube Shock Absorber

The Rancho RS5000X RS55048 shock absorber delivers exceptional on-road comfort and off-road performance through innovative Cross Tuned technology. At the core of this advanced shock is a patented rebound valving system combined with progressive compression functionality that elevates overall handling and control on any terrain.

Advanced Valving Technology:

• Exclusive Progressive Engagement Valving custom-tuned to reduce initial impacts at low speeds and minimize harsh ride characteristics
• Compression Control Valve regulates fluid transfer to absorb impacts without disc flutter and maintain consistent shock motion control
• Gas pressurized to 150 PSI to prevent damping fade by minimizing air-to-oil mixture and eliminating shock fade

Durable Construction Features:

• 16mm nitro-carburized piston rod resists scuffs and corrosion for extended service life
• 35mm sintered iron piston provides enhanced structural integrity and precise fluid control
• Twin-tube body design with increased fluid capacity for cooler operation and consistent performance
• Double-welded loops at stress areas ensure maximum durability under extreme conditions
• Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression

All-Weather Performance:

• All-weather fluid formulation withstands internal temperatures from -40°F to 248°F
• Large twin-tube construction allows for increased vehicle control at varying speeds and terrains
• Includes polyvinyl protective boot and black natural rubber bushings

Specifications:

• Extended Length: 26.54 inches
• Mounting Style: Loop bushing mount with 5/8-inch bushing ID
