Upgraded aluminium bearingblock for the Viper 989 gearbox

The Serpent SER903752 aluminium bearingblock is designed for the Viper 989 GP series to improve the robustness of the S989 two-speed transmission. Its machined aluminium body supports consistent performance under load.

Core advantages of the aluminium bearingblock

  • Material: Machined aluminium gives a stiff, lightweight housing that also aids heat dispersal during running.
  • Compatibility: Manufactured for direct fit with the Viper 989 GP (SER903018) chassis to simplify replacement.
  • Functionality: Strengthens the two-speed assembly and helps maintain reliable shifting and gearbox alignment.
The bearingblock mainly affects the drivetrain; handling changes are minimal, though improved gearbox stiffness can give more consistent power delivery under load.
Check the unit during routine maintenance intervals, looking for loosening, corrosion, or bearing wear, especially after heavy runs or impacts.
Yes, it is aimed at track and club use where a more durable aluminium solution is preferred over standard materials for reliability in competition.
