Track Tuning Pinion Pack Tamiya 53425 Aluminum Pinion Gear Set 50T/51T OP-425  [53425]

Precision Pinion Upgrade for TA-04 Chassis

The Tamiya 53425 Aluminum Pinion Gear set comes with 50T and 51T options to refine the drive behaviour of TA-04 models. Crafted from aluminium, these pinions deliver a dependable link between motor and drivetrain while keeping mass low.

Durable Aluminium Construction

Aluminium offers a good combination of lightness and toughness for pinions. The accurate tooth profile helps ensure a steady transfer of torque and reduces wear when properly installed.

Included Parts for Straightforward Fitment

You get both 50 and 51 tooth gears to change gearing quickly and experiment with ratios. The set also contains three grub screws and an allen wrench so fitting to the motor shaft is quick and simple.

Pitch Specification and Fit

These pinions use a 0.4 M (48P metric) pitch, the correct specification for TA-04 gearsets. Correct pitch is essential to avoid premature wear and to achieve consistent speed versus torque performance.
