Rancho RS55328 RS5000X Gas Shock Absorber Twin-Tube

The Rancho RS5000X RS55328 shock absorber delivers enhanced on-road comfort and off-road performance through Rancho's exclusive Cross Tuned technology. At the core of this innovative shock is a patented rebound valving system combined with an advanced compression phase that elevates overall vehicle handling and control.

Key Features:

• Progressive Engagement Valving custom-tuned to reduce initial impacts at low speeds and minimize rough ride
• Tuned Compression Control Valve regulates fluid transfer during compression to absorb impacts without disc flutter
• 16mm nitro-carburized piston rod resists scuffs and corrosion for long-term durability
• High-capacity 2.25-inch twin-tube design with 150 PSI nitrogen gas charge prevents shock fade
• All-weather fluid withstands internal temperatures from -40°F to 248°F
• 35mm sintered iron piston with glass-filled Fluon banded design for smooth operation
• Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression
• Double-welded loops at stress areas ensure structural integrity
• Black natural rubber bushings reduce road noise and suspension vibration
• Red polyvinyl protective boot shields piston rod and seal from dirt and debris

This twin-tube gas shock absorber includes all necessary mounting hardware (bushings, washers, and nuts). The larger shock body provides increased fluid capacity for cooler operation and enhanced vehicle control across varying speeds and terrain. Backed by Rancho's Limited Lifetime Warranty against defects in materials and workmanship.
