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

Precision titanium differential shaft for Mini-Z MR-02

This replacement shaft is made for Mini-Z MR-02 series differentials and is precision machined from titanium to reduce rotating mass and sharpen drivetrain feedback while keeping gear geometry unchanged.

Intended as a direct swap for the stock MR-02 differential shaft, compatibility is limited to MR-02 chassis. Inspect mating faces and check shaft runout before final assembly to ensure smooth gear engagement and correct bearing seating.

Fit following standard Mini-Z MR-02 differential service steps. Avoid forcing components, confirm the diff gears mesh freely, and apply suitable differential grease to protect bearings and keep torque transfer consistent. This item is for model tuning to refine throttle response and on-track smoothness, not for full size vehicles.
