Precision Build for Competitive 1/8 Racing

The Serpent 903390 Centax Ultra Clutch Set brings a precision approach to clutch performance in 1/8 scale vehicles. The combination of an aluminium clutch-bell, XP clutch shoe, and machined carbon flyweights reduces unsprung weight and improves power delivery for cleaner exits from corners.

Durability Meets Responsiveness

Using lightweight, hard-wearing materials, the Centax Ultra is designed to resist wear while keeping engagement consistent. The aluminium bell aids cooling under sustained running and the carbon flyweights retain their profile for dependable response lap after lap.

Compatibility and Setup Guidance

Intended for the Serpent 966 chassis, the Centax Ultra installs in the same manner as the Centax-2 series. Competent builders will find setup predictable, with familiar adjustment points for shoe clearance and spring preload.

Specifications

  • Material: Aluminum clutch-bell, machined carbon flyweights
  • Compatibility: 1/8 scale Serpent 966
  • Includes: Complete clutch set with XP clutch shoe

For serious racers wanting a light, consistent clutch package, the Serpent 903390 Centax Ultra Clutch Set balances longevity and quick response for race day tuning.

Yes, Centax-2 style springs are generally compatible, but you should verify preload and engagement with the new flyweights to maintain the desired clutch bite.
Keep the bell clean and check for burrs after heavy running. Aluminium sheds heat well but inspect the bore and keyway for wear to avoid slop in the drivetrain.
This clutch performs well on sealed tracks and prepared outdoor surfaces where sharp throttle response and light rotating mass help lap times.
Replacement XP clutch shoes and related hardware are available through Serpent parts channels; check part numbers to match the 903390 kit components.
