Race-Ready Centax-3 Pinion from Serpent 804385

The Serpent 804385 is a 21-tooth aluminium gear-pinion designed for the Centax-3 clutch assembly. It delivers a lightweight, accurately machined option for drivers looking to refine drivetrain behaviour.

Fine-Tuned Machining for Better Drive

Each pinion is machined to tight tolerances to promote even tooth contact and reduce vibration. The aluminium construction lowers rotational mass, which helps with quicker throttle transitions and cleaner power delivery.

Compatibility and Typical Roles

Made for Centax-3 equipped machines, the 21T pinion is suitable for both practice sessions and competition. Its robust build supports repeated high-speed use while keeping gear engagement smooth.

Do I need to change clutch settings when fitting this pinion?

You should check clutch engagement after fitting and make small adjustments if necessary, since weight and gear interaction can alter engagement characteristics slightly.

What are the benefits of aluminium over steel pinions?

Aluminium reduces rotating mass and can improve responsiveness. It may wear differently than steel, so inspect teeth regularly if you race frequently.

Can this pinion be re-used after heavy wear?

Minor wear can be monitored and used until performance degrades; replace the pinion when tooth profiles become visibly rounded or damaged to avoid spur gear wear.

Will a different tooth count help my lap times?

Changing pinion tooth count alters final drive. A smaller pinion raises acceleration at the cost of top speed, while a larger one reduces acceleration but increases top speed. Test to find the best trade off for your track.

Are replacement pinions and spares widely available?

Replacement Serpent parts are commonly stocked by hobby stores and online retailers. Keep a spare pinion on hand if you race often to minimise downtime.
