ARRMA 18T Mod1 Safe-D8 RC Pinion Gear - ARA311038

The ARRMA ARA311038 is an 18-tooth Mod1 pinion gear with a Safe-D8 bore, designed as a direct-fit spare for a range of ARRMA 1/8 scale RC vehicles. It slots onto the motor shaft and transfers drive to the spur gear, making it a critical component in the drivetrain. The Safe-D8 designation refers to the bore size, so check your motor shaft diameter before ordering to ensure a correct fit.
