Spec Clutch SP884 Stage 4 Performance Clutch Kit - Carbon Semi-Metallic Puck Disc

The Spec Clutch SP884 Stage 4 Clutch Kit is a high-performance racing clutch engineered for heavily modified engines that demand maximum torque capacity and instantaneous engagement. Built in the USA, this kit steps up from the Stage 3 by replacing the sprung hub with a solid 8-rivet rigid hub assembly that is heat-treated for superior strength and durability under extreme racing conditions.

The Stage 4 features a high-clamp pressure plate paired with a carbon semi-metallic puck disc, available in 3, 4, or 6-puck configurations to match your specific performance needs. The 3-puck disc offers the lightest rotating mass, the 6-puck provides the smoothest engagement of the three, and the 4-puck delivers an optimal balance of both. While the 6-puck configuration is technically street-drivable, the rigid hub design means this kit is not recommended for everyday street driving — it is purpose-built for competition use.

Kit Includes:

• High-clamp performance pressure plate
• Carbon semi-metallic puck clutch disc with rigid hub and carrier assembly (3, 4, or 6-puck)
