Fine Gear Tuning for 1/10 On-Road Cars

The Tamiya 53101 0.4 Module Pinion Gear Set is aimed at hobbyists who want precise ratio control for 1/10 on-road models. The set contains steel pinions in 20T and 21T sizes so you can tweak acceleration versus top speed. Durable steel construction helps resist wear during frequent track sessions.

Improve On-Road Driveability

Whether you are upgrading or replacing parts, these pinions fit standard Tamiya drivetrains. A hex wrench is included for fast installation, and the gears are compatible with Tamiya spur gear sets and aluminum motor mounts for smooth integration.

Will these pinions fit non-Tamiya 1/10 cars?

They are made for Tamiya models but may fit other 1/10 on-road cars if those cars use a 0.4 module pinion and the shaft diameter matches. Always check gear mesh and shaft fit before installing.

How do steel pinions affect longevity?

Steel pinions wear less than softer materials under heavy loads, so they hold up better in high speed or competitive use and need replacement less often.

Do I need to change the spur when changing pinion teeth?

You usually keep the same spur and alter the pinion to change the final drive ratio. After swapping, check mesh and clearance and make minor motor position adjustments if required.
