The GPM MG5018TS motor gear uses 20Cr steel to provide superior strength compared with many original equipment gears. A black hardening surface treatment improves wear resistance and helps keep the transmission running smoothly. The gear specification is 18 teeth with a 1.0mm module, a 5mm round motor gear hole, and retention via two 4x4 set screws. It fits ARRMA and TRAXXAS 1/8-scale models that conform to these dimensions. Always check your gear parameters before buying to ensure correct fit and function.
