Tamiya 53420 Aluminum Pinion Gear Set 40T/41T OP-420 Precision Pinions  [53420]

Precision Pinions for TA-04 Tuning

The Tamiya 53420 Aluminum Pinion Gear Set is a compact upgrade for hobbyists aiming to dial in gear ratio and throttle response. The kit contains two pinions, 40T and 41T, sized for TA-04 style drivetrains and made from lightweight aluminium to keep rotating mass low while maintaining strength.

Durable Build and Straightforward Fitment

Machined from aluminium, these pinions resist wear from regular use yet stay light to help preserve motor characteristics. The package includes three 3mm set screws plus an allen key so you can fit the gears without hunting for extra tools. They are specified for 48P metric pitch systems.

Notes on Interchange and Pitch

These 48P metric pinions are built to the Tamiya metric standard and are not directly compatible with some other makers' 48P parts. Verify your drive gear pitch before swapping to prevent poor meshing or premature wear.
