Precision Shaft Upgrade for Viper 990 GP

The Serpent 903811 Lightweight 2-Speed Shaft is tailored for the Viper 990 GP, aiming to improve shift quality and reduce unnecessary weight in the drivetrain. Manufactured to balance strength and lightness, it supports more responsive acceleration on race day.

How Lighter Shafts Improve Driveability

Lower rotating inertia means the drivetrain reacts quicker to throttle changes and gear swaps feel more precise. This upgrade suits drivers who prioritise consistent lap times and crisp throttle control.

Simple Swap-In Fitment

Specifically made for the Viper 990 GP chassis, the shaft is a direct-fit option for compatible gearboxes. Installation is straightforward with common tools and basic mechanical know-how.

Is the Serpent 903811 durable for regular racing?

Yes, it is produced from durable materials, but like any component used in racing it should be inspected regularly for signs of wear or impact damage.

Will I need different gears after fitting?

Most users retain their existing gear set. Always check gear mesh and backlash after fitting; minor adjustments may be required for optimal engagement.

Can I service the shaft myself?

Routine checks like cleaning splines and ensuring bearings are sound can be done at home. Replace the shaft if you detect bending or excessive play.
