ARRMA 13T 0.8Mod 1/8 Bore CNC Steel RC Pinion Gear - ARA311075

The ARRMA ARA311075 is a 13-tooth, 0.8 module CNC steel pinion gear with a 1/8 inch bore, designed as a direct-fit replacement or gearing option for compatible ARRMA vehicles. Machined from steel rather than moulded from softer materials, this RC pinion gear is built to handle the torque loads that come with brushless power systems. If you're running an ARRMA model and need to swap out a worn pinion or adjust your final drive ratio, the ARA311075 is the correct OEM-spec part to reach for.
