Key Features:

Rancho’s RS5000X shocks incorporate innovative technology and robust construction to provide superior suspension performance. Key features include:

• Exclusive Valving System: Custom-tuned rebound and compression valving for improved handling and shock control.
• Advanced Compression Functionality: Compression Control Valve regulates fluid transfer to absorb impacts smoothly without disc flutter.
• Progressive Engagement Valving: Reduces initial impacts at low speeds to minimize rough ride sensations.
• Durable Construction: 16mm nitro-carburized piston rod resists corrosion and scuffs for long-lasting performance.
• Large Twin-Tube Body: Filled with all-weather fluid to maintain cooler operation and withstand temperatures from -40°F to 248°F.
• Polyurethane Rebound Bumper and Rubber Bushings: Absorb ride harshness and enhance responsiveness to changing road conditions.
• Nitrogen Gas Pressurization: Pressurized to 150 PSI to reduce damping fade and foaming for consistent shock performance.
• Polyvinyl Protective Boot: Shields the shock from dirt and debris, extending service life.
• Application-Specific Piston: Expanded piston area delivers heightened control of shock motion.

Construction & Design:

The RS5000X rear shock absorber is engineered with premium materials and precision manufacturing techniques to ensure durability and performance. The 16mm piston rod undergoes nitro-carburizing, a heat treatment process that hardens the surface to resist wear and corrosion. The shock features a 35mm sintered iron piston, enhancing structural integrity and providing consistent damping force under demanding conditions.

Double-welded loops at stress points reinforce the shock’s frame, while the large twin-tube design allows for efficient heat dissipation. The shock is filled with all-weather fluid that maintains optimal viscosity across a wide temperature range, ensuring smooth operation whether in freezing cold or extreme heat.
