Kyosho Mini-Z MR-02 Alloy Titanium Differential Shaft KZ-07A by 3Racing  [KZ-07A]

MR-02 titanium differential shaft

Produced for Mini-Z MR-02 differentials, this titanium shaft reduces rotating mass to improve drivetrain sensitivity while preserving the existing gear geometry.

The shaft is intended as a direct replacement for MR-02 stock components. Check bearing seating and shaft alignment before final assembly to ensure correct gear engagement and reliable bearing performance.

Follow normal MR-02 differential maintenance steps when installing. Do not press parts in under load, verify smooth gear mesh by hand, and use an appropriate differential grease to maintain consistent torque transfer. This is a scale tuning part to enhance drive smoothness.
