Damper Rods

Product Feature

A damper rod is a pivotal part of a damper-rod fork used in front telescopic shock absorbers and rear fork shock absorbers.

The damper rod design can influence the performance of a fork, and therefore it is crucial to start thinking about damper-rod fork performance from the design stage. Yin-Ching has decades of experience in the design and manufacture of parts for motorcycle shocks. Our damper rods support the fork performance and optimal performance of the motorcycle suspension system.

  • Damper rods made of S45C medium carbon steel. The material conforms to JIS S45C / DIN CK45 / SAE 1045 and JIS S55C.
  • Damper rods suitable for both front and rear motorcycle shocks.
  • Higher tensile strength after a precision cold drawing process.
  • Wear and corrosion resistance thanks to hard chrome plating processing.
  • High-frequency hardening processing.
