Optional 10mm Centax II spring.
Serpent is pleased to release this new high-grade steel clutch tension spring. Suitable for use with the Centax II clutch system, this spring is longer than the original version by 1mm and therefore stiffer. This allows the user to tighten the clutch for optimal punch from the clutch whilst still having enough space between the coils of the spring to allow the clutch shoe to optimally travel and contact with the bell housing.
