• Durable Construction: 16mm nitro-carburized piston rod resists corrosion and scuffs, ensuring long-lasting reliability.
• Low-Friction Seals: Self-lubricating seals retain gas and oil for quicker rebound and smoother compression.
• All-Weather Fluid: Large twin-tube body filled with fluid that withstands temperatures from -40°F to 248°F for consistent shock performance.
• Compression Control Valve: Custom-tuned to regulate fluid transfer, absorbing impacts without disc flutter and maintaining shock motion control.
• Polyurethane Rebound Bumper and Rubber Bushings: Absorb ride harshness for a smoother driving experience.
• Nitrogen Gas Pressurized: Pressurized to 150 PSI to reduce damping fade and foaming for consistent shock response.
• Protective Boot: Polyvinyl boot guards against debris and environmental damage.

Construction & Design:

The RS5000X front shock is built with premium materials and precision engineering to withstand demanding conditions. Its 16mm nitro-carburized piston rod offers superior resistance to corrosion and physical wear, while the 35mm sintered iron piston enhances structural integrity for reliable operation. The twin-tube design filled with all-weather fluid ensures efficient heat dissipation and shock absorption across a wide temperature range. Double-welded loops at stress points add strength, and the polyvinyl protective boot shields critical components from dirt and debris, extending service life.

Performance & Sound

With its advanced valving and compression control, the RS5000X shock delivers improved vehicle control and handling precision, reducing body roll and enhancing stability during cornering and off-road maneuvers. The shock’s nitrogen gas pressurization minimizes damping fade, maintaining consistent performance even under prolonged use. Additionally, the polyurethane rebound bumper and rubber bushings help absorb vibrations and road noise, contributing to a quieter, more comfortable ride.
