The Serpent 6586 Centax Coil Spring is aimed at hobbyists tuning classic 720-09 200mm GP models. At 1.7mm diameter it pairs with 2.1cc and 2.5cc engines to refine clutch engagement and support routine servicing.
Designed to fit across Centax clutch variations, the Serpent 6586 provides steady performance and dependable engagement. It handles popular .12 and .15 engine sizes commonly used in vintage GP setups.
If you need firmer engagement for heavier tracks, the SP-909520 harder spring is an available alternative. Swapping springs is an easy tuning step for adapting to different circuits.
