TOPLINE D-Competition Spring Retainer (1mm down) Black – TP-437

This is a 1mm down rotary aluminium spring retainer.

By releasing the force applied in the direction of rotation that occurs when the spring expands and contracts, the original performance of the spring is maximized.

The input and output to the springs work well, which leads to turning performance and increased traction. Springs with an inner diameter of 14.0 mm ~ 14.5 mm can be used, and damper ends with an outer diameter of 7.0 mm or less at the root can be used.
