The Action Clutch Ironman Sprung (Street) kit is engineered specifically for dedicated high powered race vehicles, delivering durability and reliable performance. It features our American Sintered Iron friction material with our Dual clamp load heavy-duty pressure plate that ensures maximum torque holding capacity. The clutch engagement is aggressive with an on/off feel, without introducing clutch chatter. Some light engagement noise and gear rattle may be experienced during operation due to the nature of the product. No compromises are made in this kit, ensuring optimal performance even under extreme conditions. This kit is not intended for daily use and should only be used in race applications.

At Action Clutch, safety is our top priority. We understand how catastrophic engine or transmission damage can be caused by springs popping out which is why we use our patented, fully enclosed spring retainers to keep your investment protected at all times. Every kit is quality checked by one of our experienced engineers (with over 60 years of collective experience) and signed off as safe before being released as a finished product. This gives you peace of mind knowing that your Action Clutch will perform consistently every time.

NOTE: Purchasing the wrong type of clutch kit for your specific engine power output can result in premature clutch failure, damage to the transmission and void warranty eligibility. If you’re unsure what kit is right for you, contact Action Clutch direct.
