This ACT SB5 - HDR6 heavy - duty clutch kit is a top - notch choice for specific Subaru models. It fits 2006 - 2017 Subaru WRX, 2005 - 2012 Subaru Legacy GT and Legacy GT Spec B, 2005 - 2009 Subaru Outback XT, and 2006 - 2008 Subaru Forester XT. Note that starting mid - 2018MY production with VIN J*806877, Subaru incorporated 240mm clutch components, and this ACT kit isn't compatible with the revised OEM parts. The kit features a rigid 6 - pad race clutch disc paired with a popular heavy - duty pressure plate. You'll enjoy a light to moderate pedal feel, aggressive engagement, and it can handle up to 535 ft/lbs of torque. It's ideal for race cars only. The heavy - duty pressure plates use an exclusive diaphragm design to boost clamp load, cut deflection, and extend clutch life. The diaphragms go through a four - stage heat - treating process for great 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. The chrome - moly hub is heat - treated for strength. The lightweight and rigid design enables quicker shifts and smooth service. With this disc, engagement is harsher but shifting is faster, and it's recommended for larger clutch sizes to absorb more heat. The kit includes a 6 - pad rigid race disc, a heavy - duty pressure plate, an alignment tool, and a pilot bearing. It offers 100% clamp load testing and dynamic computer balancing for smooth high - RPM reliability, with a light to moderate pedal effort, aggressive engagement, and some increased gear rattle.
Using this ACT clutch kit is straightforward. First, make sure your Subaru model is one of the compatible ones: WRX from 2006 - 2017, Legacy GT from 2005 - 2012, Outback XT from 2005 - 2009, or Forester XT from 2006 - 2008. And double - check the VIN to ensure there are no compatibility issues. When installing, use the included alignment tool and pilot bearing to get everything in place correctly. Once installed, expect a light to moderate pedal feel and an aggressive engagement when you start using it. Remember, this kit is for race use only, so don't use it for normal daily driving. As for maintenance, keep an eye on the clutch's performance. If you notice any strange noises or a change in the pedal feel, it might be time to inspect the components. The heavy - duty pressure plates and 6 - pad race discs are built to last, but they'll still need some attention over time. Make sure to follow the manufacturer's guidelines for any future servicing or replacement parts.
