Centax Clutch Compatible Aluminium Pinion

The Serpent 909558 pinion is aimed at modelers who want a tougher, lighter gear for Centax clutch systems. Constructed from 7075-T6 aluminium, it delivers a firm balance between strength and reduced weight. A hard-anodized finish adds surface protection so the gear holds up under normal racing demands.

Feature Highlights for Serpent 909558

  • Material: High-strength 7075-T6 aluminium for reduced rotating mass
  • Durability: Hard-anodized surface treatment to minimise wear
  • Compatibility: Made to fit Centax clutch assemblies
  • Tooth Count: 18 teeth to match specified gearing ratios

How This Pinion Affects Driveability

Fitting the Serpent 909558 can sharpen throttle response thanks to lower inertial load. The robust material and finish also mean fewer replacements and more consistent runs, which helps when tuning for lap time consistency.

Can I swap this pinion into other clutch types?

The pinion is designed for Centax clutch systems. Other clutches might accept it only if the bore and spline match. Always compare dimensions before installing.

Does the hard-anodized finish change gear fit?

The anodizing adds a thin protective layer but does not significantly alter fit. Check mesh and clearances when fitting to ensure correct alignment.

Will moving to an 18t pinion affect gearing much?

Changing tooth count alters final drive ratio. An 18t pinion is intended to provide the gearing expected for Centax setups; verify your desired top speed and acceleration before changing.

Any tips for installing the Serpent 909558?

Ensure the pinion seats fully on the shaft, set correct mesh using a feeler or mesh tool, and tighten securely without overloading the gear. Recheck after a short run.
