Upgrade notes for your pinion gears

The Tamiya 50477 - 24T, 25T AV Pinion Gear set is made to deliver precise and dependable gear ratio adjustments for your RC model. These pinions let you fine tune drive characteristics without changing the spur or motor placement.

Compatibility and tuning choices

These AV pinion options fit a range of Tamiya models that accept AV-style pinions. Switching between 24T and 25T allows hobbyists to experiment with gearing to favour either stronger acceleration or a modest top speed change, depending on your overall setup.

Fitting and mesh advice

When fitting the Tamiya 50477 pinions, align the gear mesh carefully to avoid premature wear. Use the correct set screw and consider a small amount of thread-lock on the screw to keep the gear secure during running.
