Arrowmax AM-601021 Precision Pinion for Modul1

The Arrowmax AM-601021 Ultra Pinion 21T Modul1 is a precision pinion gear aimed at tuners and racers who want steady drivetrain behaviour. Spring steel construction delivers a solid balance of strength and resilience for everyday use.

Spring Steel Benefits for RC Gears

Using spring steel helps the pinion resist deformation and maintain tooth geometry under load, which supports sharper gear engagement and more predictable response on track.

Performance in Modul1 Setups

The 21T configuration is a go-to choice for many Modul1 systems, offering a practical compromise between acceleration and top-end. It fits common Modul1 pinion mounts and is easy to swap during gearing changes.

Is the Arrowmax AM-601021 suitable for racing clubs?

Yes. Its durable spring steel and 21T tooth count make it a reliable choice for club racing where consistent gear mesh is important.

Will this help reduce gear noise?

Properly installed, the precise tooth form and material properties can lead to quieter, smoother meshing compared to worn or softer pinions.

How do I check for wear?

Inspect teeth for rounding, pitting, or uneven wear and verify mesh regularly; replace when noticeable wear affects performance.
