Spec Clutch SA003 Stage 3 Performance Clutch Kit - Carbon Semi-Metallic 6-Puck

The Spec Clutch SA003 Stage 3 Clutch Kit is the ultimate street/strip performance clutch designed for heavily modified street and race engines that demand aggressive holding power without sacrificing daily drivability. Engineered for drivers who need high torque capacity with a comfortable pedal feel and quick, confident engagement, the Stage 3 sits at the top of SPEC's streetable single-disc lineup.

At the heart of this kit is a carbon semi-metallic 6-puck sprung hub disc — the proven benchmark in puck clutch drivability, service life, and torque capacity. The disc hub is double-sprung with spring cover reliefs for added flex and heat-treated components for long-term strength and durability under repeated high-stress use. A high-clamp pressure plate delivers the aggressive clamping force required for performance applications while still allowing smooth, streetable engagement.
