PN Racing Mini-Z Pro Match Delrin Pinion 7T-10T 400324

Comes with 7T, 8T, 9T, 10T each 1pcs.

The prefect match to Kyosho or PN Spur gear pitch. The gears are smooth.

There was NO loss due to the gears not meshing right.

After letting up on the throttle my car would just role and role with little loss due to the gears.

It will be make your car like stealth car with very little sound.
