Enhance Viper 989 GP Gear Operation with Serpent SER903729 XLI Gen2

The Serpent SER903729 2-speed housing XLI Gen2 is a precision replacement for the Viper 989 GP gearbox area. Manufactured to close tolerances, it supports smoother gear transitions and steady drivetrain behaviour during competitive use.

Precision Build for Predictable Shifts

Produced to suit the Viper 989 GP, this 2-speed housing offers accurate alignment and durable construction. That precision reduces unwanted movement in the gearbox and helps maintain repeatable shift performance across events.

Straightforward Upgrade and Viper Series Fit

The housing is designed for straightforward installation so experienced hobbyists can fit it without major chassis changes. It is compatible with the Viper Series, enabling an upgrade that retains your existing component layout.

Is the Serpent SER903729 compatible with modified Viper platforms?

It fits standard Viper 989 GP builds. For heavily modified platforms check shaft spacing and mounting points to confirm compatibility before installing.

How should I set gear mesh after fitting this housing?

Set gear mesh with a feeler or paper method, then secure fasteners and re-check under rotation. Proper mesh prevents noise and premature wear.

What checks are recommended before race day?

Verify gear mesh, bearing condition and screw tightness. Run a few practice laps to confirm shift timing and address any unusual noises before competing.
