Spec Clutch SU084 Stage 4 Performance Clutch Kit

The Spec Clutch SU084 Stage 4 Clutch Kit is engineered for heavily modified performance and race vehicles where instantaneous engagement, maximum torque capacity, and reduced rotating mass are top priorities. This is a solid hub version of the Stage 3 clutch, built to handle the extreme demands of competition driving.

The hub features a solid 8-rivet construction that is heat-treated for exceptional strength and durability under high-stress conditions. The kit is available in 3, 4, or 6-puck configurations using carbon semi-metallic friction material, allowing you to tailor engagement characteristics to your specific application — choose the 3-puck for the lightest rotating assembly, the 6-puck for the smoothest puck-style engagement, or the 4-puck as a balanced compromise between the two.

Important Note: Due to the rigid hub design, this clutch is not recommended for street use. It is drivable in 6-puck configuration but will exhibit harsh engagement characteristics not suited for daily driving.

Key Features:

• High-clamp pressure plate for maximum clamping force on modified engines
• Carbon semi-metallic friction material in 3, 4, or 6-puck configuration
• Solid 8-rivet hub — heat-treated for strength and durability
• High-torque rigid hub and carrier assembly for instantaneous, positive engagement
• Lightweight design reduces drivetrain rotating mass
• Includes release bearing and installation tool kit

Recommended Applications:

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

The Spec Stage 4 clutch kit delivers the aggressive, race-proven performance that serious competitors demand. If your build requires an uncompromising clutch that can withstand the punishment of full-throttle, high-RPM launches and sustained racing, the SU084 is built for the task.
