Motor pinion for 1/8-scale ARRMA/TRAXXAS

This motor gear is an RC-scale replacement pinion made from 20Cr steel with a black hardening treatment to resist wear in transmission systems. The part covers a range of tooth counts from 13T to 20T, using module 1.0mm teeth and a motor tooth diameter of 5.0mm, and it features a round motor hole secured by two set screws (4x4) for a conventional clamp-style fit.

Use this gear when you need a tough, direct-replacement pinion for 1/8-scale ARRMA and TRAXXAS applications where the listed dimensions match your motor. Before ordering, check your current pinion's tooth count, module, and bore diameter to confirm fitment; motors that match these parameters can be fitted without additional machining.
