The Kyosho MZ6BK-07 Pinion Gear Set is perfect for enthusiasts wanting reliable spare parts for Mini-Z MR-03 cars. Each pack includes three 7-tooth pinions to maintain smooth drivetrain operation during club nights and casual track use.
These pinions match the MR-03 specification and work with other Mini-Z series such as MR-015 and MR-02. Their sizing and tooth profile make them an easy swap when changing gear ratios or replacing worn parts.
Replacing a worn pinion is a quick maintenance job that helps restore crisp throttle response. The Kyosho MZ6BK-07 setup needs only basic tools and minimal adjustment for proper meshing.
