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

Tamiya 94577 8T pinion gear pack explained

The Tamiya 94577 8T Plastic Pinion Gear set supplies ten 8-tooth plastic pinions for Mini 4WD cars. These parts fit a range of Mini 4WD models including Mini 4WD PRO, Dangun Racers and R/C Mini 4WD platforms.

How they work and which chassis they suit

These pinions ensure steady tooth engagement and help transmit motor power reliably to the drivetrain. They are compatible with several chassis designs, allowing you to test performance across different builds.

Using the 8T for track setup

The 8T option plays a key role in adjusting your gear ratio, impacting how quickly the car accelerates and its ultimate top speed. Try different pinions to tune the car for either short bursts or sustained speed.

Combining with other upgrades

Use the 8T pinions as part of a wider upgrade plan, pairing them with performance motors, sealed bearings and tuned tyres to reduce friction and improve lap times.
