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.

This gives you peace of mind knowing that your Action Clutch will perform consistently every time.

Size up at least once or twice if you buy these
Color: Black-satin, Size: Medium
I really wanted these pants to work because they actually look very nice and the material feels decent for a tuxedo pant. However, the sizing is completely off. I normally know my size pretty well, but these arrived and were way too small. I ended up reordering two different pairs in larger sizes trying to find the right fit, and even then, I couldn't get it quite right. Since I was in a major time crunch for an event, I eventually had to give up because I didn't have the time to go back for a third pair. It is a shame because the flat front style is exactly what I was looking for and the functionality of the clasp and zipper seemed solid. The value for money would be great if the fit was consistent, but the headache of returning and reordering makes it tough to recommend unless you have plenty of time to experiment with the sizes. If you decide to grab these, definitely plan on ordering at least one or even two sizes larger than what you usually wear. They have a nice professional look to them, but the durability of the fabric doesn't matter much if you can't actually get them on.

Runs EXTREMELY small
Color: Black-satin, Size: 3X-Large
Ordered a 3X but got a XS…i am a 42-44, got the 3X to have tapered to my fit, but upon opening the pants, it seemed they may be more of a 32-34 and the adjustable straps aren’t really adjustable, they are just buckles sewed in place for design. The 3X tag sewn in is a complete lie! Only giving 1 star because they did have the satin tuxedo stripe on the side!
