Precision 64P pinion from Arrowmax

The Arrowmax AM-364039 Pinion Gear is crafted for pilots who want reliable mesh and long life from their drivetrain components. Forged from 7075 aluminium, this 39 tooth, 64 pitch pinion balances toughness with lightweight design for consistent running.

Designed for stable drivetrain behaviour

Good pinion quality matters for control and efficiency. The Arrowmax 64P 39T pinion gear helps smooth power delivery and reduce gear noise, making it suitable for a wide range of models that use 64 pitch gearing.

Benefits of using 7075 aluminium

7075 aluminium is prized for its high strength relative to weight, which helps resist deformation at high RPM. That durability keeps gear engagement healthy and supports repeatable lap times without adding unnecessary mass.

It is compatible with standard 64 pitch spur gears. Always double-check the motor shaft size and keying to confirm proper fitment.
Yes. If your vehicle uses 64 pitch gearing, this pinion suits different disciplines; adjust gear ratio to match the intended use and terrain.
Set a precise, slight clearance to avoid tight spots. Run-in briefly at low speed, then recheck mesh and clasp bolts after initial runs.
