Spec Clutch SM884-2 Stage 4 Clutch Kit - Carbon Semi-Metallic Puck Disc

The Spec Clutch SM884-2 Stage 4 Clutch Kit is a high-performance clutch system engineered for heavily modified engines that demand maximum power transfer, instantaneous engagement, and reduced rotating mass. Built as a solid-hub evolution of the Stage 3 design, the Stage 4 is purpose-built for serious motorsport applications where street drivability is secondary to performance.

Key Features:

• High-clamp pressure plate for maximum clamping force and torque capacity
• Carbon semi-metallic friction disc available in 3, 4, or 6-puck configurations — choose 3-puck for the lightest rotating assembly, 6-puck for the smoothest engagement, or 4-puck as a balanced compromise
• Solid 8-rivet hub with heat-treated assembly for exceptional strength and durability
• High-torque rigid hub and carrier assembly designed to eliminate slippage under extreme load
• Includes bearing and tool kit for complete installation

Intended Use:

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

Note: The Stage 4 rigid hub design produces a firm, aggressive engagement characteristic. While the 6-puck configuration offers slightly more manageable engagement, this clutch is not recommended for street use due to its unsprung, solid-hub construction.
