Precision pinion tuning with Tamiya 40503

The Tamiya 40503 Aluminum Pinion Gear (14T) offers a clean, lightweight option for hobbyists adjusting gear ratios. Its aluminum build delivers efficient power transfer and helps reduce rotating mass for snappier handling.

Durability without Extra Weight

Constructed from quality aluminum, this pinion resists everyday wear while keeping your car responsive. It is a practical choice for those who want durability without sacrificing vehicle agility.

Compatibility Notes

Compatible with a broad selection of Tamiya motor arrangements, the Tamiya 40503 is straightforward to fit. Verify your motor shaft diameter and spline type to ensure correct installation and long service life.
