Precision Pinion for Viper 989 GP Drive Trains

The Serpent 903800 - Viper 989 GP Aluminum 19T Pinion Gear is a precision aluminium pinion produced for the Viper 989 GP. Its 19-tooth profile promotes smoother torque transition and helps maintain drivetrain efficiency during competitive running.

Quality Aluminium Manufacture

Engineered from quality aluminium, the Serpent 903800 pinion provides a solid balance between toughness and lightness. Accurate machining ensures true tooth profiles and reliable engagement with compatible spur gears.

Tuned for Circuit Performance

At 19 teeth the pinion offers a measured compromise between low-end acceleration and higher top speed, suitable for circuit layouts where controllable power delivery matters most.

Is the Serpent 903800 suitable for high power setups?

It is suitable for many race setups, but monitor gear wear and motor load with high output systems. Correct mesh and regular inspection will prolong service life.

Can I polish or treat the pinion surface?

Surface polishing offers little benefit; focus on clean installation and correct mesh. If using a protective coating, ensure it does not alter tooth profile or fitment.

What signs indicate it is time to replace the pinion?

Replace the pinion when you see rounded, chipped or missing teeth, excessive noise at full power, or increased backlash that affects lap consistency.
