Upgrade Your Viper 989 GP Drivetrain

The Serpent 903800 - Viper 989 GP Aluminum 19T Pinion Gear is an aluminium pinion tailored for the Viper 989 GP. Its 19 teeth help smooth torque delivery and contribute to an efficient, responsive drivetrain setup.

Aluminium Strength with Low Mass

Built from resilient aluminium, the Serpent 903800 pinion balances durability and low rotating weight. That balance aids handling and reduces strain on the spur gear when meshed correctly.

Gearing Choice for Competitive Runs

The 19T option sits in the middle of the gearing range, offering a reliable mix of acceleration and gearing stability for race environments. It makes a sensible upgrade or replacement for worn stock parts.

Most installations are straightforward; verify shaft diameter and set screw style match your motor. If the bore differs, use the correct adapter or seek the matching pinion bore option.
Aluminium can show wear sooner than hardened steel in high load situations, but quality machining and correct mesh reduce premature wear. Inspect regularly and replace if teeth deform.
After fitting, confirm gear mesh, tighten the set screw, check motor alignment, and run at low speed to listen for unusual noise before full-power testing.
