Performance Gear for Viper 989 GP

The Serpent SER903733 57-tooth XLI Gen2 2-speed gear is an aftermarket option aimed at improving drivetrain feel on the Viper 989 GP. Its tooth profile is matched to the XLI Gen2 interface for reliable shifts.

Compatibility Notes

This unit is engineered for the Viper 989 GP layout and is best used with compatible XLI Gen2 components. It is a simple swap for racers wanting sturdier engagement under load.

Setup Suggestions

Check bearings and shafts for play before fitting the 57T gear, and set a correct mesh clearance. Run a few light-power laps then recheck fasteners to maintain smooth operation.

Does the 57T require gearbox changes?

No major gearbox redesign is needed when used on the intended Viper 989 GP and XLI Gen2 setup, though minor clearance checks are recommended.

What pinion sizes work well with 57T?

Pinion choice depends on track layout and motor characteristics; smaller pinions favour acceleration while larger ones increase top speed, so tune accordingly.

Any tips to reduce gear noise?

Ensure correct mesh, use fresh bearings, and avoid overtightening the gearbox; a small run-in period can also help noise settle down.
