Precision titanium shaft for MR-02 competition setups

This precision machined titanium shaft is intended for Mini-Z MR-02 series differentials. It reduces rotating mass to sharpen drivetrain response while preserving the original gear geometry for consistent handling.

Compatibility is limited to MR-02 chassis and the part functions as a direct replacement for the stock differential shaft. Inspect bearing seats and measure runout where possible to confirm correct gear alignment and smooth engagement.

Installation should follow standard Mini-Z MR-02 differential servicing procedures. Avoid forcing components, verify free gear mesh during assembly, and apply an appropriate differential grease to maintain even torque transfer. Use this shaft as a tuning component to improve throttle feedback and drive control under competitive conditions.

Is the shaft a direct drop in for MR-02 diffs?

Yes. It is designed as a direct replacement for the MR-02 stock differential shaft without changing gear geometry.

What inspection steps ensure correct installation?

Check bearing press fit, confirm minimal shaft runout, and rotate the assembly to verify smooth mesh before final sealing.

Will reduced inertia affect tuning choices?

Lower rotating mass can sharpen response and may require minor diff or throttle mapping adjustments to achieve the desired handling balance.
