Upgrade the Viper 989 GP Drivetrain

The Serpent SER903636X 2-speed Gear 61T SL8 XLI V2 is a straightforward upgrade part for racers and club drivers who want dependable shifting from their Viper 989 GP. It focuses on predictable engagement and consistent performance under load.

Compatibility Details

Made to fit the Serpent Viper 989 GP (SER903018), this 61T gear matches the original geometry so it integrates without modiļ¬cation on a correctly prepared car.

Why This Gear Matters

Good gears keep horsepower where you expect it. The 61T SL8 XLI V2 helps avoid sudden slip or lag during gear changes, giving more consistent lap times and less drivetrain fuss between meetings.

Can I run this on different track surfaces?

Yes, the gear itself is surface agnostic. Ensure your diff and clutch setup suit the surface to make the most of the gearbox behaviour.

Do I need special tools to fit it?

Basic RC workshop tools and a feel for mesh adjustment are enough. A torque driver and calipers help ensure accurate reassembly.

Is this part race legal?

The gear follows standard Serpent fittings. Check your class rules if you race under spec regulations, but it is a like-for-like replacement for the Viper 989 GP transmission.
