Spec Clutch SB073-2 Stage 3 Performance Clutch Kit with Carbon Semi-Metallic 6-Puck Disc

The SPEC SB073-2 Stage 3 Clutch Kit is a high-performance clutch system engineered for drivers who demand aggressive, high-torque capability without sacrificing everyday streetability. Featuring a carbon semi-metallic 6-puck sprung hub disc, this kit delivers an industry-leading combination of drivability, service life, and torque capacity in a single puck-style package. The kit includes a billet non-SAC (non-self-adjusting clutch) pressure plate, making it the ideal upgrade for vehicles converted to a single-mass flywheel setup.

The hub assembly is double sprung with spring cover reliefs for enhanced flexibility under load, while heat-treated internal components provide long-term strength and durability. The high-clamp pressure plate works in concert with the carbon-graphite friction material to deliver consistent, repeatable engagement whether you're on the street or at the track.
