The GPM MG5018TS motor gear is manufactured from 20Cr steel to provide improved load resistance over standard parts. A black hardening treatment raises surface hardness for better wear life and more consistent transmission efficiency. Key specifications include 18 teeth, 1.0mm module, a 5mm round-shaped motor gear hole, and retention by two 4x4 set screws. This component is compatible with ARRMA and TRAXXAS 1/8-scale models that share these gear dimensions. Confirm existing gear measurements before installation to ensure proper engagement and fitment.
