Spec Clutch ST824 Stage 4 Clutch Kit - Carbon Semi-Metallic Puck Disc

The Spec Clutch ST824 Stage 4 Clutch Kit is engineered for heavily modified, high-performance engines where instantaneous engagement, maximum torque capacity, and reduced rotating mass are the top priorities. Built as a solid-hub evolution of the Stage 3 platform, this kit delivers race-proven clamping force and aggressive engagement characteristics suited for dedicated competition use.

Key Features:

• High-clamp pressure plate for maximum torque transfer under extreme power loads
• Carbon semi-metallic puck disc available in 3, 4, or 6-puck configurations — choose 3-puck for the lightest rotating mass, 6-puck for the smoothest engagement, or 4-puck as a balanced compromise
• Solid 8-rivet rigid hub — heat-treated for superior strength and durability
• High-torque rigid carrier assembly for maximum power transfer with minimal flex
• Kit includes pressure plate, puck disc, release bearing, pilot bearing, and alignment tool

Intended Use:

• Drag Racing
• Road Racing
• Drift
• Rallye
• Pulling
• Circle Track

Important Note: The Stage 4's rigid hub design makes it suitable in 6-puck configuration for limited street use, but it is not recommended as a daily driver due to its aggressive, instantaneous engagement characteristics. This kit is intended for vehicles with heavily modified engines where race performance takes priority over street drivability.
