Refine Viper 989 GP Performance with the Serpent 63T Unit

The Serpent SER903638X 2-speed 63T unit provides a straightforward way to restore consistent gear engagement on the Viper 989 GP. Its design integrates cleanly with the Viper Series transmission layout for dependable operation on tarmac and prepared tracks.

Compatibility and Installation Notes

Made to match the Viper 989 GP gearbox geometry, the 63T gear installs without exotic modifications. Accurate tooth profiles and tight tolerances reduce slop and help preserve mating parts for extended service intervals.

Built for Sustained Use

Engineered for repeated track sessions, the 63T gear maintains uniform power transfer across shifts. Its sturdy manufacturing helps minimise break-in issues and supports consistent lap times for regular drivers.

Will this gear fit if I run different spur sizes?

The 63T gear is focused on the gearbox side; spur size changes can affect overall ratios but will not prevent the SER903638X from fitting provided the gearbox spacing is unchanged.

How should I check mesh after fitting?

Set a small amount of backlash, rotate the transmission to inspect tooth engagement, and run the car slowly to verify quiet, even meshing before full-power testing.

Is any break-in required?

A short running-in under light load helps seat the gears; avoid prolonged full-power laps until you confirm the mesh and lubrication are correct.
