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

Mini-Z MR-02 titanium diff shaft

Made for Mini-Z MR-02 series differentials, this titanium shaft reduces rotational mass to deliver crisper drivetrain feedback while keeping gear geometry unchanged.

It is a direct replacement for the original MR-02 differential shaft. Inspect mating components and check for shaft runout during assembly to ensure smooth gear operation and correct bearing alignment.

Install using standard MR-02 diff service steps. Avoid forcing parts into place, confirm gears mesh without binding, and apply a suitable diff grease to maintain consistent torque transfer. This is a tuning component intended to improve model performance.
