Construction & Design:

The RS5000X shock absorber is meticulously engineered with high-grade materials to ensure long-lasting performance. The nitro-carburized piston rod provides exceptional resistance to wear and corrosion, critical for off-road conditions. The 35mm sintered iron piston enhances structural strength, while the twin-tube design filled with all-weather fluid promotes efficient heat dissipation, preventing shock fade during extended use.

Attention to detail is evident in the double-welded loops at stress points, which improve durability under heavy loads. The polyvinyl protective boot safeguards the shock shaft from dirt and debris, extending service life. Additionally, the fluon-banded piston reduces friction for smoother operation and improved responsiveness.
