Durable 7075 Pinion for Precise Mesh

The Arrowmax AM-364055 64P 55T pinion gear is a must-have part for RC builders aiming to refine drivetrain accuracy. Machined from 7075 aluminum, it balances light weight with solid strength to keep gear mesh reliable during high RPM runs.

Suited for Track and Club Racing

Whether you are dialing in a touring car setup or prepping a 1/10 scale racer, this 64-pitch 55-tooth pinion delivers predictable power transfer and stable engagement at speed. Its tooth profile is optimised for consistent performance under load.

Fitment and Practical Use

This pinion fits a broad range of electric RC cars and works well for drivers who change ratios frequently. The construction helps trim a few grams from rotating mass while maintaining tooth strength for regular use.

What shaft sizes does this pinion support?

Check the bore and set screw arrangement on your motor. The Arrowmax AM-364055 can be reamed or fitted to common motor shaft sizes used in 1/10 electric classes with appropriate adapters.

How should I set gear mesh with this 64P pinion?

Use a thin piece of paper between pinion and spur, slide the motor until the paper drags slightly, then tighten motor mounts. Recheck under load and adjust to avoid binding or excess play.

Can I lighten this pinion further for sprint racing?

Material removal can reduce mass but may weaken teeth. If weight is critical, consider a thinner hub or choose a pinion specifically designed for racing where tooth count and strength remain suitable.
