The GPM 20Cr steel motor gear is manufactured from heat treated 20Cr steel with a black hardening finish to increase strength and resist wear under load. Offered in tooth counts from 14T up to 20T with a 1.0mm module, it is compatible with motors that use a 5mm tooth diameter. The gear fits via a round bore and is secured by two 4x4 set screws to keep a reliable connection to the motor. It is suitable for 1/8-scale ARRMA and TRAXXAS models that match these dimensions; always confirm gear parameters before fitting.
