Team Associated ASC21532 Pinion Gear 16T

The pinion gear mounts on the motor shaft and drives the spur gear, making it the component that sets your final drive ratio. Tooth count is your primary gearing adjustment: it determines how the car trades acceleration against top speed and directly affects how hard the motor works and how much heat it makes over a run.

This Team Associated pinion, part number 21532, is a 16 tooth gear in .5 module pitch sized for a 2.3mm motor shaft. The package includes one pinion gear plus one M3x2.5 set screw, so you have the hardware needed to secure it to the motor shaft without hunting for a replacement grub screw.

It fits the Reflex 14B, Reflex 14T, Reflex 14R, Reflex 14R Hoonitruck, Reflex 14MT Monster Truck, Reflex 14B Ongaro, and Reflex 14B Buggy. As a genuine Team Associated part it installs directly on the stock motor with no modification. Use it as a straight replacement for a worn or stripped pinion, or add it to your gearing selection to tune the car for a specific track layout.
