Tamiya 9994577 - 8T Pinion Gears (Purple) for Mini 4WD Setup

The Tamiya 9994577 - 8T Pinion Gears Set (Purple, 10 Pieces) gives you ten purple 8T pinions ideal for fine tuning Mini 4WD transmissions. They are produced to consistent tolerances so builders can rely on repeatable gear changes.

Where They Fit

These 8T pinions are suitable for most standard Mini 4WD gearboxes that accept an 8-tooth pinion. Their standard tooth form makes them easy to swap when experimenting with different ratios during practice sessions.

Race Day Adjustments

Running an 8T pinion often yields stronger initial acceleration, handy for quick corner exits and short straight sections. Regular checks of mesh and shaft alignment will help keep lap times consistent.

Do these work with both brushed and brushless motors?

Pinion gears themselves are motor-agnostic; fit depends on pinion bore and motor shaft dimensions. Verify the bore size and shaft diameter to ensure compatibility.

Can I mix these with other brand gears?

Mixing is fine if tooth count and pitch match. For consistent performance, use pinions with the same tooth profile and inspect meshing after installation.

What tools do I need to swap pinions?

Basic hobby tools like pliers and a small driver are usually enough. A pinion puller or press helps with tight fits but is not always necessary.
