The Kyosho MZW206-1 spur gear is intended for use in Mini-Z ball differential configurations, including MR-03 cars, and offers reliable engagement for both maintenance and light tuning. It is a commonly used spare for Mini-Z enthusiasts.
Compatible with MR-015, MR-02 and MR-03 Mini-Z models, this spur gear is well suited for routine servicing or refreshing an ageing drivetrain. Its profile is made to match ball differential setups used across the Mini-Z range.
Before installing the MZW206-1, clean the gearbox area and check bearings and pinion condition. Fit the gear with correct mesh, verify smooth rotation, and perform periodic inspections to detect wear early.
