Heavy-duty 1/8 pinion for ARRMA and TRAXXAS

The MG5020TS pinion is an RC-scale replacement designed for 1/8-scale ARRMA and TRAXXAS applications, focused on durable, consistent power transfer in model drivetrains. The gear is manufactured from 20Cr steel and finished with a hardened black treatment to increase wear resistance compared with standard stamped or softer alloys.

Key mechanical details include a 20-tooth count, 1.0mm module, and a motor bore diameter of 5.0mm in a round-hole format. The part fastens to the motor shaft with two set screws sized 4x4, so confirm that your motor accepts that bore and module combination before purchasing.

When changing gearing this pinion provides a straightforward upgrade option where improved wear resistance and steady gear mesh are priorities. Choose this part only after matching module, bore, and tooth count to your existing spur gear and motor flange set up.

How do I verify this 20T pinion will fit my motor?

Confirm your spur gear uses a 1.0mm module and that the motor either has a 5.0mm round bore or can be adapted. Measure shaft and flange dimensions before ordering to ensure correct fitment.

What is the recommended method to secure the pinion?

The pinion clamps to the shaft using two 4x4 set screws. Tighten the screws evenly, confirm concentric seating, and then recheck mesh under rotation.
