Traxxas Hardened Pinion Gear Mod 1.0 17T (5mm Bore)

Traxxas Hardened Pinion Gear gives you a direct, heavy-duty upgrade when your stock pinion needs more wear resistance. This 17-tooth, Mod 1.0 pinion fits 5mm shafts and is made of hardened steel for use with steel spur gears; it also ships with a set screw for secure mounting.

Key Features

• Includes set screw — hardware included to secure the pinion to the motor shaft right out of the box.
