Precision Pinion for Racing Setups

The Tamiya 53731 Racing Clutch Pinion Gear, with 21 teeth, is built for precise first gear adjustments. It helps racers refine drivetrain behaviour to suit engine characteristics and circuit demands.

Dial in Your Drive

Fitting the Tamiya 53731 makes it easier to tweak acceleration and top speed trade offs. Small changes to pinion size directly affect throttle response and gearing harmony with your spur gear.

Fits Multiple Tamiya Models

This pinion works across several Tamiya kits and is a convenient option for workshops with multiple cars. It also complements other Tamiya pinions like 53733, 53734 and 53735 for broader gear range testing.

Will this pinion need different clutch settings?

You may need to adjust clutch engagement slightly after changing pinion size to maintain smooth power transfer and avoid slippage under load.

How often should I inspect the pinion?

Check the teeth and set screws regularly, especially after heavy runs, and replace the pinion if you notice wear or damaged teeth to prevent spur gear damage.

Does the 21T suit short tracks?

Yes, a 21T can help enhance acceleration on shorter circuits where rapid exit speed matters, though final choice depends on your motor and spur combination.
