Action Clutch ACR-2075-SPR Ironman Sprung Single Disc Sintered Iron Clutch Kit

The Action Clutch ACR-2075-SPR Ironman Sprung (Street) Single Disc Clutch Kit is engineered specifically for dedicated high-powered race vehicles, delivering exceptional durability and reliable performance under demanding track conditions. This kit is ideal for performance enthusiasts who want maximum torque holding capacity without stepping up to a multi-disc system.

At the heart of this kit is American Sintered Iron friction material — extremely durable and purpose-built for high heat environments. The sprung disc hub design provides smoother engagement compared to the unsprung (rigid) variant, making it more manageable for street-to-track transitions while still delivering the aggressive clamping force race applications demand.

Key Features:

• American Sintered Iron friction material for superior durability and heat resistance
• Sprung disc hub for smoother engagement versus unsprung designs
• Dual clamp load heavy-duty pressure plate for maximum torque holding capacity
• Up to 250% increased holding capacity over factory clutch kits
• Reinforced heavy-duty drive straps
• 4-stage heat-treated diaphragm spring
• Patented fully enclosed spring retainers to prevent spring failure and protect drivetrain components
• American-grade high-quality rivets throughout
• 100% dynamically spin balanced
• SFI Spec 1.1 certified
• No clutch chatter — light engagement noise and some gear rattle is normal

Kit Contents:

• Heavy-duty sintered iron clutch disc (sprung hub)
• Heavy-duty pressure plate assembly
• Release / throwout bearing
• Clutch alignment tool
• Pilot bearing or bushing (when applicable)

Break-In Requirements: 500 street miles — keep RPM under 4,500, no more than half-throttle, and no boost (if applicable). Proper break-in is required to retain product warranty, ensure longevity, and achieve full holding capacity.

Important Notes: This clutch system features an aggressive on/off engagement feel and is specifically engineered for track use applications. It is not recommended for daily driving. Best paired with an Action Clutch steel or chromoly flywheel for optimal performance.
