The Kyosho MZ6BK-09 Pinion Gear Set includes three 9-tooth pinions that help keep Mini-Z MR-03 series cars running with consistent gear engagement. These replacement gears are useful for routine service and to prevent unexpected downtime during events.
Manufactured for the Mini-Z MR-03 platform, these pinions also fit MR-015 and MR-02 variants. They are a practical choice for hobbyists replacing worn parts or carrying spares for quick roadside fixes. Installation is simple so you can return to the track without long delays.
Use this set for regular maintenance to preserve drivetrain integrity and predictable handling. The 9T pinions are suited to close indoor layouts and practice sessions where consistent gearing matters.
