These are .6 mod pinion gears. These are used on cars such as the Tamiya
touring cars(this works on the TA01 and the TA02, but NOT on the TA03). They
also work on some other Tamiya cars, and on the Kyosho Ultima Pro, and the
Ultima Pro XL.
These gears are available in sizes from 12 to 24 teeth.
Includes a pinion set screw.
