GPM Racing 20CR Steel Motor Gear 12T (Module:1.0mm,motor Tooth Diameter:5.0mm) (MG5012TS)

GPM replacement pinion details

This pinion is an RC replacement gear made from 20Cr steel with a black hardening treatment to improve wear resistance in transmission systems. It covers tooth counts from 13T to 20T, uses module 1.0mm teeth and a 5.0mm motor bore, and mounts on a round shaft secured by two 4x4 set screws for a standard clamp-style fit.

Choose this pinion for ARRMA and TRAXXAS 1/8-scale builds when the dimensions listed match your motor. Confirm tooth count, module and bore diameter on your existing pinion to ensure fitment without additional machining.

What key dimensions must match my motor?

Ensure tooth count (13T-20T), module 1.0mm, bore diameter 5.0mm and that your motor accepts a round-hole pinion secured by two 4x4 set screws for correct compatibility.

Can this pinion be fitted to different motor types?

Yes, as long as the motor shaft and mounting match the specified bore and set screw arrangement; otherwise you may need an alternate pinion or shaft adapter. Write Product Review Please sign in your account before you can write any review. Sign In Close
