Design Notes for YZ-2T Rear Shock Shaft

This shaft is an RC-scale replacement intended for the rear shock of the 2WD racing truck YZ-2T. The titanium-coated surface is used to reduce surface wear and preserve consistent piston travel under frequent running.

The piston is fastened to the shaft with screws, improving alignment and operating accuracy during compression and rebound. When original shafts become worn or scored, this part can be fitted as a direct replacement to recover shock performance.

Although the shaft does not alter spring rate or the viscosity of shock oil, a smoother piston surface promotes steady damping response and more reliable tuning outcomes across sessions.

Specifications

  • Item Shock shaft for rear shock
  • Material Titanium-coated surface
  • Model Number Z2-S2TRTA
  • Compatibility Rear shock of YZ-2T, Supported chassis B-YZ2T

Use this shaft to replace worn rear shock shafts on YZ-2T setups and restore smooth stroke and consistent shock action for track and practice use.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this shaft change the feel of my shocks?

The shaft itself does not change spring stiffness or oil damping, but maintaining a smoother shaft surface can make the damping feel more consistent and predictable.

Does the screw-mounted piston improve setup repeatability?

Securing the piston with screws helps keep it aligned, which improves repeatability of damping adjustments and reduces variation between runs.

Is this a straight swap for damaged shafts?

Yes. This shaft is intended as a direct replacement for worn or scored rear shock shafts on the YZ-2T rear shocks.

Any installation tips to avoid damage?

Clean mating surfaces, lightly lubricate as appropriate, and tighten the piston screws evenly. Avoid over tightening to prevent distortion.
