Serpent SER909520 Centax II/III 1.8 Spring (10mm) - Racing Grade Clutch Spring  [SER909520]

Upgrade path with Serpent SER909520 1.8 spring

The Serpent SER909520 Centax II/III Spring is a targeted upgrade for Centax II and III clutch systems. Its 10mm length and higher spring rate give stronger preload than the OEM spring, helping achieve firmer clutch engagement while maintaining reliable coil spacing.

Dialling in engagement

The increased stiffness makes it possible to run tighter clutch gaps for snappier initial acceleration and better throttle control. The spring still allows even travel of the shoe so contact with the bell remains consistent across the rev range.

Who should fit this spring

This part is aimed at racers and enthusiasts using Centax II or III clutches who want a firmer feel. It is suited to both track conditions and spirited club running where quicker response is beneficial.
