Action Clutch ACR-1177 Ironman Unsprung Clutch Kit

The Action Clutch ACR-1177 Ironman Unsprung Clutch Kit is engineered specifically for dedicated high-powered race vehicles, delivering exceptional durability and reliable performance under extreme conditions. This professional-grade kit features American Sintered Iron friction material paired with a dual clamp load heavy-duty pressure plate that ensures maximum torque holding capacity, offering approximately 250% increased holding capacity over the factory clutch.

Key Features:

• Unsprung American Sintered Iron disc for extreme durability and heat resistance
• Dual clamp load heavy-duty pressure plate with nearly double the clamping force
• Aggressive on/off clutch engagement without introducing clutch chatter
• Reinforced drive straps and American-grade rivets for maximum strength
• Premium release bearing and pilot bearing included
• Clutch alignment tool included for proper installation
• Quality checked and certified by experienced engineers with over 60 years collective experience

Performance Characteristics:

This Ironman kit delivers lightning-fast, aggressive engagement with an on/off feel ideal for track use, drag racing, road racing, and drift applications. Some light engagement noise and gear rattle may be experienced during operation due to the rigid, unsprung design. The sintered iron material provides excellent repeatability and endurance, making this kit the go-to choice for racers seeking affordable, high-torque holding capacity without upgrading to a multi-disc system.

Important Application Notes:

This clutch kit is specifically designed for track-use applications only and is not recommended for daily street driving. Using an unsprung clutch disc on a stock or lightly modified engine in daily/street driven vehicles can cause premature failure and break the rivets on the clutch disc hub. Proper break-in of 500 miles is required, keeping RPMs under 4500 and using no more than half-throttle. All Action Clutch products are 100% hand-assembled in the USA and backed by quality assurance standards.
