The XRAY 358584 medium clutch springs are engineered for 1/8 scale vehicles to deliver steadier engagement and longer life under heavy use. Their construction focuses on resisting fatigue from repeated race starts and aggressive driving.
The redesigned coil form helps prevent early failure, so springs last longer between changes. The medium spring rate provides a controllable engagement suited to mixed track conditions and racing formats.
These springs are a straightforward upgrade for racers aiming to stabilise clutch behaviour and improve predictability during acceleration phases.
