Serpent 903199 Centax Flyweights PTFE .21 Performance Upgrade  [SER903199]

Precision Machined Flyweights Built for Consistent Clutch Response

Meet the Serpent 903199 Centax Flyweights, designed for .21 engines and made using a precision machining process. These PTFE flyweights replace softer molded parts with a denser, more durable design for steadier behaviour during race runs.

Harder, Denser Material for Longer Life

Produced from solid stock and incorporating carbon and graphite, these machined flyweights are harder than standard molded types. That increased density helps reduce wear and keeps performance consistent across different track conditions.

Sharper Engagement with User Adjustment

The geometry of these flyweights promotes a more positive clutch engagement by pushing the weights outward rather than letting them trail. Each weight also includes a secondary hole for a grub screw, allowing fine adjustment of clutch bite to match your setup.
