Fitment Information: This clutch kit fits 2006 - 2017 Subaru WRX, 2005 - 2012 Subaru Legacy GT / Legacy GT Spec B, 2005 - 2009 Subaru Outback XT, and 2006 - 2008 Subaru Forester XT. Note that starting from mid - 2018MY production with VIN J*806877, Subaru incorporated 240mm clutch components. This ACT clutch kit and flywheels are not compatible with the revised OEM parts. Features: The ACT SB5 - HDG4 kit comes with a sprung, 4 - pad race clutch disc and a well - loved heavy - duty pressure plate. You'll experience a light to moderate pedal feel, aggressive engagement, and it can handle up to 535 ft/lbs of torque. It's perfect for high - horsepower street cars or racing. The ACT heavy - duty pressure plates use an exclusive diaphragm design. It increases clamp load, reduces deflection, and extends clutch life. All diaphragms go through a four - stage heat - treating process for top - notch performance. The precision cover stampings on the pressure plates ensure rigidity and consistency. The 4 - pad spring - centered race disc dampens torsional vibrations for quiet operation and resists failure in tough conditions. The spring retainers offer great spring support, reduce stress, and boost strength. With this disc, engagement is harsher but shifting is faster, making it a great fit for smaller engines. Feel: You'll have a moderate to heavy pedal effort, aggressive engagement, and OE to mild gear rattle. Recommended Use: Ideal for high - horsepower street or race use. Torque Capacity: 535 ft/lbs. ACT Difference: It's 100% clamp load tested and dynamically computer - balanced for smooth high - RPM reliability. What's Included: The kit includes a 4 - pad sprung race disc, a heavy - duty pressure plate, an alignment tool, and a pilot bearing.
Using your ACT Heavy - Duty 4 - Puck Sprung Clutch Kit is straightforward. First, make sure your vehicle is on a flat surface and the engine is off. Use the included alignment tool to properly install the clutch disc and pressure plate. The pilot bearing should be placed carefully in its designated spot. When you start using the clutch, expect a moderate to heavy pedal effort and an aggressive engagement. It's great for high - horsepower driving, whether on the street or the race track. But remember, it might cause a bit of gear rattle, which is normal. As for maintenance, keep an eye on the clutch performance. If you notice any unusual noises or a change in pedal feel, it could be a sign that something needs checking. Also, since this clutch can handle high torque, avoid overloading it beyond its 535 ft/lbs capacity. And don't forget, this kit isn't compatible with Subaru's revised 240mm OEM components starting from mid - 2018MY production with VIN J*806877, so double - check your vehicle's specifications before installation.
