SB9-HDSS kit features ACT's most popular Heavy Duty pressure plate and most popular street disc. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's Performance street discs are the most popular disc purchased. They feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs feature a reduced marcel for faster shift action to complement ACT pressure plates. Quiet operation with increased strength and reliability. Monoloc is a one-piece, direct replacement or upgrade to the standard, two-piece wedge collar and wire ring featured in pull-type clutches. The spring tension of the segmented retaining ring is carefully calculated and tested for optimal performance. It provides uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications. Monoloc's hardened chrome-moly steel construction will provide years of service.

- Went stage two and oem clutch couldn't hold. So went with this one and its great. Holds good and not too chattery. Well worth it.
- I am getting ready to buy my 3rd act heavy duty clutch kit for my third subaru. these are excellent clutches, thats why i keep buying them! now, if only i could hold onto a car long enough to not have to buy a new clutch every other year! ha!
Great clutch kit for the price and reliabilty!
- I have over 155,000 miles on my 2002 Subaru WRX sedan, and have had two ACT street clutch / lightened flywheel kits installed over the time. I could not be happier with the performance the ACT kits have given me. It's an easy install and the results are great. The clutch holds great, has a solid increased pedal feel to it, and there isn't too much chatter. 5 / 5 Stars for a great product!
