The Spec stage 1 clutch features an integrally molded carbon kevlar-based, high performance organic lining that offers smooth engagement and excellent life.

Bridging the gap between stage 2 and stage 3, the Spec 2+ clutch offers drivability and engagement quality characteristic of the stage 2, but with a 15-20% higher torque capacity.

The Spec Stage 3 clutch kit is designed for street and race cars that require an aggressive but streetable engagement and high torque capacity.

The Spec Stage 3+ is the flagship stage for a high powered street or race car that requires manageable and friendly engagement.

The Spec Stage 4 clutch kit is a solid hub version of the stage 3. The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration.

The Spec Stage 5 clutch kit features a full-metallic disc with the highest possible friction co-efficient. It is street drivable but not street-friendly.
