Spec Clutch SC401-2 Stage Performance Clutch Kit - 1

The Spec Clutch SC401-2 Stage 1 Clutch Kit is a high-performance organic clutch system engineered for drivers who demand more than a stock clutch can deliver, without sacrificing daily drivability. Built around an integrally molded carbon Kevlar-based organic friction disc, this kit delivers smooth, predictable engagement with excellent service life — ideal for street driving and a wide range of performance and track applications.

The friction disc features an integrally bonded steel backing that provides superior structural integrity under high clamp loads and elevated temperatures. The double-sprung hub incorporates spring cover relieves for enhanced flexibility, and all hub components are heat treated for long-term strength and durability. Combined with a high-clamp pressure plate, the SC401-2 delivers meaningful torque capacity improvements over OEM while retaining a comfortable, street-friendly pedal feel.
