Accurate gearing from Arrowmax AM-464066

The Arrowmax AM-464066 64P 66T pinion is built for model tuners who want refined gear control. The 66-tooth layout on a 64-pitch profile helps deliver consistent power transfer across different track and surface conditions.

Suited to Many Spur Gear Setups

With its standard 64-pitch specification, this pinion mates cleanly with common spur gears, allowing easy swaps to change ratios for acceleration or top speed without complex mods.

Lightweight and Precisely Cut

Precision cutting reduces unnecessary rotating weight and supports steady motor performance, letting your motor run cooler and reducing drivetrain stress during long sessions.

Is this pinion suitable for on-road and off-road use?

Yes, the 64P 66T profile is a common choice for both on-road and many off-road rigs. Suitability depends on spur gear type and vehicle clearance rather than tooth count alone.

Can I change gear ratio without altering the motor mount?

Often you can swap pinion sizes on the same motor plate, but larger changes may require repositioning the motor or using a different spur to maintain correct mesh.

What signs show the pinion needs replacing?

Look for tooth wear, noisy gear mesh, or vibration under load. If the mesh skips or chips appear, replace the pinion and inspect the spur for matching wear.
