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

Sharper launches using Serpent SER909520 1.8

The Serpent SER909520 Centax II/III Spring is built to improve clutch response on Centax II and III setups. With a 10mm length and a firmer coil profile than standard, it raises clutch tension to deliver a quicker, more controlled engagement while preserving smooth coil travel.

How it affects clutch behaviour

The uprated stiffness supports tighter clutch adjustments, which can give stronger initial hook and improved control off the line. Coil spacing remains sufficient to keep the clutch shoe making clean, consistent contact with the bell.

Compatibility notes and applications

Made specifically for Centax II and Centax III clutches, this spring suits racers and hobbyists who want to dial in firmer engagement for competitive starts or responsive casual running.
