ARRMA 17 Tooth 8mm Shaft Kraton 8S Pinion Gear - ARA311037

The ARRMA ARA311037 is a 17-tooth pinion gear with an 8mm shaft bore, designed as a direct-fit drivetrain component for the ARRMA Kraton 8S. Pinion gears are a critical part of the drivetrain, transferring power from the motor to the spur gear, and replacing a worn or damaged pinion with the correct tooth count keeps your Kraton running at the intended gear ratio. This is a genuine ARRMA part, so fitment to compatible Kraton 8S models is exact with no modification required.
