Construction & Design:

The RS5000X is built with durability and performance in mind. Its 16mm piston rod undergoes nitro-carburizing, a heat treatment process that significantly enhances surface hardness and corrosion resistance. The shock’s 35mm sintered iron piston provides a robust internal structure capable of withstanding rigorous use. Double-welded loops at critical stress points add strength to the mounting areas, ensuring long-term reliability.

The twin-tube design is filled with specially formulated all-weather fluid that maintains consistent damping characteristics across extreme temperatures, from freezing cold to intense heat. Protective polyvinyl boots guard against dirt and moisture, extending the life of the shock absorber.
