The Kyosho MZ6BK-07 Pinion Gear Set provides a straightforward replacement option for Mini-Z MR-03 owners. With three 7-tooth pinions included, this pack helps restore smooth power delivery and reduces drivetrain noise.
These pinions are manufactured to suit the MR-03 chassis and are also compatible with MR-015 and MR-02 models. Their compatibility makes them a practical spare part for trackside repairs and home maintenance.
Replacing worn pinions with the Kyosho MZ6BK-07 set is a quick maintenance task that improves throttle response. Basic hand tools are sufficient to perform the change and get you back on the track fast.
