Action Clutch ACR-3664 Stage 4 Performance Clutch Kit 1MD Unsprung Ceramic Disc

The Action Clutch ACR-3664 is a high-performance Stage 4 clutch kit engineered for enthusiasts who demand maximum holding capacity and extreme durability. This competition-grade clutch system is designed for high horsepower applications that encounter heavy-duty street use and frequent drag racing, road racing, or drifting.

Key Features:

• Heavy-duty single diaphragm pressure plate with reinforced drive straps for increased clamping force
• Unsprung MIBA ceramic disc (available in 4 or 6 puck configuration) for instant engagement and rapid heat dissipation
• Extremely lightweight unsprung hub design provides instant power transfer with no flex
• Light pedal feel with aggressive engagement characteristics
• Outstanding holding capacity for modified and high horsepower engines
• Complete kit includes pressure plate, clutch disc, release bearing, alignment tool, and pilot bearing when applicable

Important: This Stage 4 clutch kit features an unsprung ceramic disc and is recommended for race use applications only. The aggressive engagement and unsprung design are not suitable for daily driving or constant on/off engagement environments typical of street use. Using an unsprung clutch kit on a stock or lightly modified engine in daily driving conditions can cause premature wear and damage to the clutch disc hub rivets. Some clutch chatter and increased gear rattle are normal characteristics of this performance-oriented clutch design.
