Precision Pinion for Smooth Power Delivery

The Arrowmax AM-601025 Ultra Pinion 25T Modul1 is a precision-cut gear made to last in performance RC applications. Its spring steel build provides toughness under load while keeping gear mesh tight and predictable.

Advantages of a Spring Steel Pinion

Spring steel resists bending and fatigue, which helps retain accurate tooth engagement during long sessions. The Arrowmax Ultra Pinion supports consistent driveline performance with lower risk of sudden failure.

Applications and Setup Notes

As a 25T Modul1 pinion, it fits many common motor and spur gear combos. Ideal for tuning top speed or low-end grunt, it performs well on both track and rough surfaces when installed with correct mesh.

Do I need a specific shaft size?

Confirm your motor shaft diameter and set screw size before fitting. The Arrowmax AM-601025 will require correct shaft match and a secure grub screw to prevent movement under load.

Will changing pinion teeth affect motor temps?

Altering the tooth count changes final ratio and can affect motor load. More teeth typically lower motor RPM and reduce heat, while fewer teeth raise RPM and may increase temperature.

How do I check for gear wear?

Inspect tooth edges for rounding or chips and check for uneven patterns on the spur. Replace the pinion if you see bent teeth or consistent slippage during runs.
