Improve Drive Feel with Tamiya Aluminium Pinions

The Tamiya 53425 Aluminum Pinion Gear set, supplied with 50T and 51T options, is intended to sharpen the drive characteristics of TA-04 chassis vehicles. Made from quality aluminium, these pinions are built to take regular use while keeping weight down.

Built for Durable, Smooth Running

Aluminium gears reduce rotating mass while delivering robust service life when properly meshed. Precision cutting ensures quieter operation and steady power delivery whether cruising or racing.

Easy Ratio Swaps Included

Both 50 and 51 tooth sizes are supplied so you can quickly experiment with gearing. The kit also contains three grub screws and an allen wrench for a straightforward motor shaft install.

Specifications and Compatibility

These gears are 0.4 M (48P metric) pitch, matching the TA-04 drivetrain specification. Using the correct pitch avoids premature wear and helps you dial in the correct speed versus torque tradeoff.
