Serpent 909559 - 19T Aluminium Centax Pinion Gear - Lightweight Race Part  [SER909559]

Precision 19T pinion for Centax clutches by Serpent

The Serpent 909559 - 19T Aluminium Centax Pinion Gear is engineered from 7075-T6 aluminium to offer high strength without excess weight. The hard anodised surface reduces wear and keeps gear teeth true under load, so you get consistent mesh and longer service life between changes.

Why a 19-tooth choice matters

A 19-tooth profile provides a useful compromise between acceleration and top speed, improving driveability on mixed surfaces. It helps the clutch and drivetrain behave more predictably during throttle transitions, which is valuable when dialing in lap times.

Where this pinion fits

Designed for Centax clutch systems, this pinion suits a range of models that use the Centax pattern. It is ideal for hobbyists upgrading worn parts or tuning gearing for specific track conditions.
