Track-Tuned Pinion for the Viper 989 GP

The Serpent 903800 - Viper 989 GP Aluminum 19T Pinion Gear is a precision aluminium component made to pair with the Viper 989 GP. Its 19-tooth design aids in smoother power transfer and helps maintain efficient drivetrain operation under race loads.

Robust Aluminium Construction

Produced from quality aluminium alloy, the Serpent 903800 pinion is built to resist wear while keeping mass low. This combination improves vehicle responsiveness and gives consistent gear engagement lap after lap.

Gearing That Suits Circuit Racing

The 19T sizing delivers a compromise between punchy acceleration and usable top speed for circuit layouts. Swap pinions to fine tune acceleration or engine braking feel depending on surface and layout.

Can I use this pinion with different spur gears?

Yes, the 19T pinion will mesh with compatible spur gears of the correct pitch. Always check tooth engagement and spacing before full power runs.

Is special lubrication required for an aluminium pinion?

Typically no special lube is needed; keep the gear free of grit and inspect teeth regularly. If using thin gear grease, apply sparingly to avoid attraction of debris.

Does this pinion affect motor cooling?

Changing pinion size alters load on the motor but does not directly change airflow. Monitor motor temps after gearing changes and adjust cooling or gearing if temperatures rise.
