The GPM 20CR steel motor gear is crafted from hardened 20Cr and finished with a black hardening process to improve toughness and wear life. Supplied in tooth options from 14T to 20T and using a 1.0mm module, it suits motors with a 5mm tooth diameter. The round motor bore is locked in place by two 4x4 set screws to maintain a dependable drive connection. It is intended for 1/8-scale ARRMA and TRAXXAS vehicles that meet these gear dimensions; verify compatibility before fitting.
