The Kyosho MZW206-1 spur gear is purpose-made for Mini-Z ball differential assemblies like the MR-03, offering reliable tooth engagement for everyday running. Its fitment is straightforward for hobbyists servicing their cars.
This spur gear matches Mini-Z variants such as the MR-015, MR-02 and MR-03. Its design works well in ball differential set-ups and is a practical choice when swapping worn parts or refreshing drivetrain components.
Before fitting the MZW206-1, wipe away dirt and old lubricant from surrounding parts. Fit the gear, confirm the mesh and spin the assembly by hand to ensure there is no binding. Regular checks prevent unexpected failures on the track.
