Race-Oriented Centax-II Clutch for Tuners

The Serpent 903219 PRO Centax-II clutch kit focuses on consistent engagement and reduced rotational drag. High-grade ceramic bearings and lightweight machined components help maintain smooth operation under sustained use.

Main Upgrades and Benefits

  • Lightweight Clutch Bell: Less inertia for snappier throttle response on corner exits.
  • Ceramic Bearings: Smoother rolling action and enhanced wear resistance compared to standard bearings.
  • Hardened Clutch Spring: Delivers a firmer preset while letting the shoes travel freely for reliable engagement.
  • Aluminum SPP Clutch Plate: Works with the yellow clutch shoe for repeatable performance.
  • Machined Flyweights: Standard fitment improves activation timing and feel.

Specifications

  • Clutch Housing: SP-909513 Centax II Light
  • Support Plate: SP-903212 Aluminum SPP
  • Flyweights: SP-903199
  • Coil Spring: SP-909520 1.8 Hard
  • Bearing: SP-1380 5x13 Ceramic
  • Thrust Bearing: SP-1388 5x10 Ceramic

The Serpent 903219 PRO Centax-II clutch kit is a solid choice for hobbyists who demand consistent clutch action and lower drivetrain losses during competitive running.

If your engine uses a Centax-II style flywheel pattern, the kit is designed to fit. Compare the bolt pattern and bearing diameters to be sure.
Ceramic bearings perform well with light oil or dry setups; avoid heavy greases that can increase drag. Check bearings periodically and clean if needed.
The yellow clutch shoe is matched to the included aluminum SPP plate for ideal contact. It may work with other plates but expect changes in engagement behavior.
Use the 1.8 hard spring as a starting point; softer conditions may benefit from lighter springs while grippier tracks can run the harder spring for firmer engagement.
