Spec Clutch SA063 Stage 3 Performance Clutch Kit

The Spec Clutch SA063 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand aggressive torque capacity without sacrificing daily drivability. Delivering a comfortable pedal feel with quick, responsive engagement, the Stage 3 is the go-to choice for drivers who push their vehicles hard across a wide range of performance disciplines.

At the heart of this kit is a carbon semi-metallic 6-puck sprung hub disc — the benchmark puck clutch for balancing 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 needed under sustained high-stress conditions. The high-clamp pressure plate ensures a firm, positive lockup under demanding loads.

Key Features:

• High-clamp performance pressure plate for maximum clamping force
• Carbon semi-metallic 6-puck sprung hub disc (4-puck configuration available upon request)
• Double-sprung hub with spring cover reliefs for flexibility and heat-treated components for durability
• Carbon-graphite friction material for superior life and torque capacity
