Precision Pinions for 1/10 On-Road Models

The Tamiya 53101 0.4 Module Pinion Gear Set provides two steel pinions in 20 and 21 tooth counts to help you tune final drive characteristics on 1/10 on-road cars. Steel pinions keep tooth form stable under load for repeatable performance.

Simple Upgrade, Reliable Fit

Perfect for replacing worn parts or testing different ratios, this set includes a hex wrench to speed up changes. The gears are compatible with Tamiya spur gear sets and aluminium motor mounts to ensure straightforward integration.

Are these pinions suitable for competitive racing?

They are suited to competitive use thanks to the durable steel construction, but ensure your overall setup including motor and ESC matches the gearing choice for your class rules.

How should I check gear mesh after fitting?

Set a light mesh with a sheet of paper between pinion and spur, tighten the pinion, then run the gears by hand to confirm smooth engagement. Adjust as necessary to prevent binding.

Will these work with stock Tamiya motors?

Yes, they are designed for Tamiya drivetrains and are compatible with many stock motors. Verify final ratio and monitor motor temperature after switching to a different pinion size.
