• Durable Construction: Double-welded loops at stress points and application-specific sintered iron piston enhance structural integrity.

Construction & Design:

The RS5000X front strut is built with durability and performance in mind. Its nitro-carburized piston rod offers superior resistance to corrosion and wear, ensuring longevity even in demanding environments. The strut’s piston is crafted from sintered iron tailored to the specific vehicle application, providing enhanced strength and precise control of shock motion. Protective polyvinyl boots shield critical components from dirt and debris, while the twin-tube design filled with all-weather fluid maintains optimal operating temperatures and consistent damping characteristics.

Attention to detail in welding and material selection results in a robust suspension component that withstands the rigors of both daily driving and off-road adventures.
