The XRAY 348541 Ultra Stable Clutch Spring is engineered to provide consistent clutch engagement for RX8 and NT1 cars, giving drivers a dependable baseline for setup work and race day. It is built to preserve its behaviour through repeated use.
Where the #348540 Conical Clutch Washer Spring Set can show variation, the XRAY 348541 gives a more uniform response so drivers can count on clutch behaviour across different sessions and track states.
The manufacturing pre-compression applied to the XRAY 348541 reduces the risk of spring set and secures its length and spring rate. The slightly shorter finished spring holds its characteristics even after extended running.
