Tamiya 94577 - 8T Plastic Pinion Gear Set for Mini 4WD Tuning  [94577]

Tamiya 94577 8T pinion gear set summary

The Tamiya 94577 8T Plastic Pinion Gear set includes ten 8-tooth plastic pinions intended for Mini 4WD use. These parts are suitable for Mini 4WD PRO, Dangun Racers and a variety of R/C Mini 4WD chassis.

Compatibility and transmission role

These pinions are made to provide a steady tooth interface for smooth torque transfer from the motor to the wheels. They are versatile across multiple chassis designs and useful when testing gear ratios.

Tuning for speed and acceleration

Fitting an 8T pinion changes the effective gear ratio, which in turn influences acceleration and maximum speed. Racers can experiment with different pinions to match track layout and strategy.

Practical upgrade advice

Use the 8T pinions alongside improved motors and precision bearings to lower drivetrain losses. Matching tyre choice and chassis adjustments will help you get the best results from the gear change.
