Spec Clutch SN632 Stage 2 Performance Clutch Kit with Kevlar Disc

The Spec Clutch SN632 Stage 2 Clutch Kit is a high-performance, street-and-track-ready clutch system built for drivers who demand more torque capacity and durability than a stock or Stage 1 setup can provide. Engineered and hand-built in the U.S.A., this kit steps up friction performance with a pure Kevlar disc and high-clamp pressure plate without sacrificing daily drivability.

The Stage 2 features a segmented or full-faced pure Kevlar friction disc with a steel backing plate, delivering excellent drivability comparable to the Stage 1 while offering increased torque capacity and extended service life. The double-sprung hub incorporates spring cover reliefs for enhanced flexibility, while heat-treated internal components provide the strength and durability needed for demanding driving applications.
