Tuned gearing with Arrowmax AM-464066

The Arrowmax AM-464066 64P 66T pinion is aimed at tuners who demand repeatable gear performance. Its 66-tooth design on a 64-pitch cut helps maintain steady torque delivery across different driving conditions.

Works with Standard Spur Gear Options

This pinion follows the common 64-pitch standard, making it simple to combine with many spur gears for fine-tuning gearing ratios to match track or surface demands.

Precision Finish for Reliable Runs

Accurate tooth profiling reduces vibration and keeps the drivetrain operating smoothly, which supports consistent lap times and reduces the chance of unexpected wear during intense use.

Can I use this pinion with brushless motors?

Yes, it can be used with brushless setups provided the motor shaft and mount allow proper mesh. Confirm bore fit and alignment before first run.

What gear ratio changes does a 66T pinion give compared to smaller sizes?

A larger pinion like 66T raises the final drive ratio versus smaller pinions, generally increasing top speed while lowering acceleration. Select based on track layout and motor powerband.

How do I inspect the pinion after heavy use?

Remove the pinion and check each tooth for deformation or chips, inspect the bore for ovaling, and verify set screws and any retaining hardware are secure before reassembly.
