Precision Pinion for Competitive RC

Racers and tuners who demand accurate tooth engagement will value the Serpent 120129 Hard Aluminum Pinion Gear. With a 64 pitch and 42 teeth, this pinion is machined from durable aluminum to deliver consistent power transfer and reliable service life across a variety of track surfaces.

Built to Last Under Load

Hard aluminum construction boosts durability while keeping weight low, helping the pinion withstand high rpm use without adding unnecessary mass to the drivetrain. That balance makes it well suited to fast circuits where control and response matter.

Flexible Tuning Options

The 64P 42T setup offers a wide tuning window for adjusting acceleration versus top speed and pairs with many spur gears to suit different track types and driving styles.

Will this pinion fit my buggy or touring car?

It can fit many vehicles but always confirm your spur gear pitch and motor shaft spline match 64P and the chosen pinion bore before fitting.

Is it suitable for high rpm brushless motors?

Yes, it works with brushless setups provided the mesh is set correctly and the pinion is secured to prevent slippage under high load.

How should I monitor wear on an aluminum pinion?

Inspect teeth for rounding, chips or uneven wear, listen for unusual noise and replace the pinion if engagement becomes sloppy to protect the spur and motor.
