ACT Xtreme Clutch Kit 6 Puck Solid Disc Subaru STI 2004-2021 / Legacy GT Spec B 2007-2009 | SB10-XTR6

This ACT clutch kit (SB10-XTR6) is a high-performance solution for your Subaru. It fits 2004 - 2021 Subaru STI and 2007 - 2009 Subaru Legacy GT Spec B models. Note that Legacy GT spec.B models need to use the STI flywheel to use this clutch. The kit features a rigid 6 - pad race clutch disc paired with an Xtreme pressure plate. You'll experience moderate to heavy pedal effort, aggressive engagement, and it can handle up to 766 ft/lbs of torque. It's perfect for race use only. The ACT Xtreme pressure plates use an exclusive diaphragm design to boost clamp load, reduce deflection, and maximize clutch life. The diaphragms go through a four - stage heat - treating process for top - notch performance. The pressure plates have precision cover stampings for rigidity and consistency. The 6 - pad rigid race discs are made of high - quality ceramic friction materials, with a heat - treated chrome - moly hub for strength and durability. The lightweight and rigid design enables quicker shifts and smooth service. Engagement is harsher but shifting is faster. This disc is great for larger clutch sizes to absorb more heat. The Monoloc is a one - piece direct replacement or upgrade, with carefully calculated spring tension for optimal performance. It ensures proper alignment. It comes with a 6 - pad rigid race disc, an Xtreme pressure plate, an alignment tool, a pilot bearing, and a release bearing.

Using this ACT clutch kit is straightforward. First, make sure your Subaru model is either a 2004 - 2021 STI or a 2007 - 2009 Legacy GT Spec B. If you have a Legacy GT spec.B, don't forget to use the STI flywheel. When installing, use the included alignment tool to ensure everything is in place. The pilot bearing and release bearing should be installed according to the standard procedures. During use, expect a moderate to heavy pedal effort and an aggressive engagement. This is normal for a high - performance clutch. Since it's designed for race use only, don't use it for regular daily driving. Regarding maintenance, check the clutch periodically for signs of wear. The high - quality materials used in the disc and pressure plate should last a long time, but if you notice any issues like slipping or strange noises, have it inspected by a professional. The Monoloc is built to last, but keep an eye on its alignment and functionality. With proper use and maintenance, this clutch kit will serve you well on the race track.
