Tamiya 9994577 - 8T Purple Pinions for Mini 4WD

The Tamiya 9994577 - 8T Pinion Gears Set (Purple, 10 Pieces) is a handy pack for builders wanting matched 8T pinions in a bright purple finish. These parts are made to hold up to regular running while keeping gear mesh stable.

Fit and Use

Designed for common Mini 4WD gear trains that accept 8-tooth pinions, these gears let you quickly change setups to suit different track layouts. Their consistent tooth profile simplifies tuning work between practice sessions.

Tuning for Speed or Acceleration

Fitting an 8T pinion tends to favour quicker acceleration at the cost of absolute top speed, useful on twisty circuits or tracks with frequent cornering. Keep an eye on mesh and alignment to prevent premature wear.
