FAQ

Replacement 1/8 motor pinion

The MG5020TS is offered as a direct-style pinion for 1/8-scale ARRMA and TRAXXAS models, engineered to sustain consistent gear engagement in hobby drivetrains. Heat-treated black finish and 20Cr steel construction aim to improve surface hardness versus softer, stamped alternatives.

Specifications from the source state a 20-tooth count and a 1.0mm module, with a 5.0mm round bore for motor fit. Two 4x4 set screws secure the part to the motor shaft; verify your motor flange before fitting to avoid fitment issues.

Use this pinion when swapouts demand improved wear resistance and predictable mesh. Ensure the tooth count, module, and bore match your existing spur and motor setup prior to installation.

Does the 20Cr steel and hardened finish make a noticeable difference?

Yes, the 20Cr material and hardened black treatment increase surface wear resistance compared with common softer pinions, helping longevity under high-load or abrasive conditions.

Can this pinion be used with a D-shaped or modified bore?

The part is produced with a 5.0mm round bore. If your motor uses a different shaft shape, use an appropriate adapter or confirm your motor can be modified to accept the round-bore pinion.
