Spec Clutch SA603 Stage 3 Performance Clutch Kit with Carbon Semi-Metallic 6-Puck Disc

The Spec Clutch SA603 Stage 3 Clutch Kit is engineered for heavily modified street and race vehicles that demand aggressive torque capacity without sacrificing everyday drivability. Designed for drivers who push their cars hard across multiple disciplines, the Stage 3 delivers a comfortable pedal feel and quick, confident engagement whether you're commuting or competing.

At the heart of this kit is a carbon semi-metallic 6-puck sprung hub disc — the leading puck-style clutch disc in drivability, service life, and torque capacity. The hub is double-sprung with spring cover reliefs for added flexibility, while heat-treated internal components provide the strength and durability required under sustained high-stress use. A high-clamp pressure plate ensures maximum clamping force to handle the torque demands of modified engines.
