Features:

ACT's SB10-XTSS kit features a sprung, performance street clutch disc paired with their ever popular Xtreme pressure plate. What does this mean for you? Well, that means that you will have moderate to heavy pedal effort with smooth positive engagement and the ability to handle up to 598ft/lbs of torque on your Subie. This clutch kit is best suited for street and race use.

ACT Xtreme 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 higher 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.

Act.

If your looking for a replacement clutch dont looks elsewhere. This clutch is awesome and holds great. Clutch pedal is a little stiffer as you would expect for stronger clutch. Driving as a daily with this is great.

Holding strong

Loving the clutch! Holds strong. Was the little chatter I read about act clutches, but went away after about 250 miles of break in. Paired perfectly with the torque solution motor mounts

Paired this with the ACT Streetlite flywheel. The clutch feels really good, not too much of a difference from stock in my opinion. Really great response and good engagement.
