• 35mm Sintered Iron Piston: Enhances structural integrity for consistent performance under stress.
• Polyurethane Rebound Bumper and Rubber Bushings: Absorb ride harshness and improve responsiveness to changing road conditions.
• Large Twin-Tube Body with All-Weather Fluid: Maintains cooler operation and reliable damping across extreme temperatures from -40°F to 248°F.
• Nitrogen Gas Pressurized to 150 PSI: Minimizes air-to-oil mixing to reduce damping fade and foaming during extended use.
• Compression Control Valve: Custom-tuned to regulate fluid transfer, preventing disc flutter and maintaining shock motion control.
• Polyvinyl Protective Boot: Shields critical components from dirt and debris for enhanced durability.

Construction & Design:

The RS5000X shock absorber is built with durability and performance in mind. Its 16mm nitro-carburized piston rod resists corrosion and physical damage, ensuring longevity even in harsh environments. The 35mm sintered iron piston offers exceptional strength and stability, while the twin-tube design filled with all-weather fluid promotes consistent damping and heat dissipation. Double-welded loops reinforce stress points, and a polyvinyl boot protects against contaminants, making this shock absorber a rugged choice for demanding applications.
