Yokomo Z2-S2TRTA Shock Shaft for Rear Shock of YZ-2T  [Z2-S2TRTA]

Rear shock shaft for YZ-2T

This is an RC-scale replacement shock shaft designed for the rear shock of the 2WD racing truck YZ-2T. The shaft has a titanium-coated surface aimed at reducing surface wear and maintaining smoother piston travel under frequent use.

The shaft design fixes the piston with screws, which helps maintain piston alignment and operating accuracy during compression and rebound cycles. In practical setup work it functions as a direct swap-in component where shaft wear or scoring has affected shock performance.

In tuning terms the shaft itself does not change spring rate or oil damping, but by preserving a smoother piston stroke it supports consistent damping behavior and repeatable adjustments across runs.

Use this shaft when replacing worn rear shock shafts on YZ-2T setups to restore smoother stroke and maintain shock consistency during practice and racing sessions.
