Spec Clutch SN463 Stage 3 Performance Clutch Kit Carbon Semi-Metallic 6-Puck

The Spec Clutch SN463 Stage 3 Clutch Kit is engineered for heavily modified street machines and purpose-built race cars that demand both high torque capacity and real-world drivability. Designed to deliver an aggressive yet streetable engagement, this kit strikes the balance between performance and daily usability with a comfortable pedal feel and consistent engagement characteristics.

At the core of the Stage 3 kit is a carbon semi-metallic 6-puck sprung hub disc — Spec's proven puck clutch design recognized for its outstanding balance of drivability, service life, and torque capacity. The hub is double-sprung with spring cover reliefs to absorb drivetrain shock and provide flexibility, while heat-treated internal components deliver the strength and durability required under sustained high-stress use.

Key Features:

• High-clamp performance pressure plate for maximum clamping force
• Carbon semi-metallic 6-puck sprung hub disc (4-puck configuration available on select applications)
• Double-sprung hub with spring cover reliefs for flexibility and shock absorption
• Heat-treated components for long-term strength and durability
• Carbon-graphite friction material for excellent wear characteristics
• Includes release bearing and installation tool kit

Intended Use: Street, Drag Racing, Drift, Road Racing, Rallye, Pulling, Autocross

The Spec Stage 3 kit represents a significant step up from organic-lined clutches, making it the ideal choice for modified engines that have outgrown stock or Stage 1/2 components but still require a drivable street clutch. Note: flywheel not included.
