Tune your Viper 989 GP drivetrain

For owners of the Serpent Viper 989 GP, the Serpent SER903771 2-speed gear set offers a way to refine gear engagement and gain steadier acceleration control. It is a practical upgrade for competitive drivers and serious hobbyists.

Made to match the Viper transmission

The SER903771 components are shaped to fit the Viper 989 GP layout, delivering improved shift sequencing and helping maintain consistent power application through corners and on the straight.

Quality for repeated use

Produced with attention to durability, the SER903771 set copes with frequent shifting and hard running. Proper setup and periodic checks will help the gears perform reliably over many sessions.

Compatibility with earlier variants depends on the transmission layout; verify part fitment before ordering, as some older models may need different components.
Regular checks of gear mesh, bearings and shift parts, plus cleaning and light lubrication, will reduce wear and keep shifting smooth.
A 2-speed set influences how and when power is delivered, which can affect acceleration feel and top end behaviour; final results depend on the overall setup and gearing choices.
