Precision Pinions Tamiya 53425 Aluminum Pinion Gear Set 50T/51T OP-425  [53425]

Upgrade Your TA-04 with Tamiya Pinion Gears

The Tamiya 53425 Aluminum Pinion Gear set, featuring 50T and 51T gears, is engineered to improve drivetrain response on TA-04 chassis cars. Machined from quality aluminum, these pinions link the motor to the drivetrain with reliable, lightweight construction suited to road and club racing.

Lightweight Metal for Consistent Performance

Aluminum provides a good balance of low weight and toughness, helping preserve motor efficiency while resisting wear. The accurate machining keeps gear runout low for smooth power transfer during spirited driving.

Simple Fit and Multiple Ratios

The set gives both 50 and 51 tooth options so you can tune acceleration or top speed. The package includes three grub screws and an allen wrench to make fitting to the motor shaft straightforward.

Gear Pitch and Chassis Fit

These pinions use a 0.4 M (48P metric) pitch to match the TA-04 drivetrain. That pitch is important for correct mesh and reliable speed and torque balance in your setup.
