Tamiya 94577 8T Plastic Pinions overview

The Tamiya 94577 8T Plastic Pinion Gear set contains ten identical pinions made for Mini 4WD builds. These gears are intended to improve drivetrain efficiency across popular Mini 4WD platforms, including Mini 4WD PRO, Dangun Racers and R/C Mini 4WD models.

Drive function and fitment

These 8-tooth plastic pinion gears deliver consistent engagement from motor to axle, supporting smooth power transfer. They fit a variety of chassis layouts, so you can test them on different setups depending on track demands.

Race tuning and gear ratio choices

Choosing an 8T pinion affects both acceleration and top speed, making it a key part of race tuning. Swapping pinions is a straightforward way to adapt your car to fast straights or technical sections by changing the gear ratio.

Upgrade pairings and tips

While the 8T pinion is a basic replacement part, it works well when paired with quality motors and low-friction bearings to reduce drivetrain loss. Try different tyres and chassis adjustments alongside the pinions to find the best overall balance for your track.
