Spec Clutch SF103 Stage 3 Performance Clutch Kit - Carbon Semi-Metallic 6-Puck

The SPEC SF103 Stage 3 Clutch Kit is engineered for heavily modified street and race applications that demand aggressive torque capacity without sacrificing everyday drivability. Offering a comfortable pedal feel and quick, confident engagement, the Stage 3 is the go-to upgrade for drivers who push their vehicles on the street and at the track.

At the heart of this kit is a carbon semi-metallic 6-puck sprung hub disc — widely regarded as the leading puck-style clutch design for its balance of drivability, service life, and torque capacity. The hub features a double-sprung design with spring cover reliefs for added flexibility, along with heat-treated components for long-term strength and durability under both low and high stress conditions. A 4-puck configuration is also available when specified at the time of ordering.
