Arrowmax Ultra Pinion 21T Modul1 - Built to Last

The Arrowmax AM-601021 Ultra Pinion 21T Modul1 is a heavy-duty pinion gear engineered for racers and hobbyists who value precision and longevity. Constructed from premium spring steel, it resists wear and keeps mesh stable under load.

Advantages of Spring Steel Construction

Spring steel delivers high strength with controlled flexibility, helping the gear preserve tooth profile under stress. That durability means fewer gear swaps and more consistent performance during demanding runs.

Compatibility with Modul1 Drivetrains

Made to integrate with Modul1 layouts, the 21T tooth count gives a practical balance of acceleration and top speed for many RC car setups. It fits common pinion mounts and is straightforward to install for routine tuning.
