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 mid - 2018MY production with VIN J*806877, Subaru incorporated 240mm clutch components, and ACT clutch kits and flywheels aren't compatible with these revised OEM parts. Features: ACT's SB5 - HDG4 kit combines a sprung, 4 - pad race clutch disc with a well - loved Heavy Duty pressure plate. You'll enjoy a light to moderate pedal feel, aggressive engagement, and the ability to handle up to 535ft/lbs of torque in your Subaru. It's ideal for high - horsepower street cars or race use. The ACT Heavy Duty pressure plates use an exclusive diaphragm design. This design boosts the clamp load, cuts down on deflection, and extends the clutch's lifespan. All 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 4 - pad spring - centered race disc has a spring - center to damp torsional vibrations, ensuring quiet operation and resisting failure even in tough conditions. The spring retainers have wraparound spring windows and thicker stampings for better spring support, less stress, and increased strength. With this disc, engagement is harsher but shifting is faster, and it's great for smaller engines with smaller disc sizes. Feel: It requires moderate to heavy pedal effort, offers aggressive engagement, and has OE to mild gear rattle. Recommended Use: Perfect 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 comes with a 4 - Pad Sprung Race Disc, a Heavy Duty Pressure Plate, an Alignment Tool, and a Pilot Bearing.
Using your ACT Heavy Duty Clutch Kit: First, make sure your vehicle is in the list of compatible models. When installing the kit, use the included alignment tool to ensure proper alignment of the clutch disc. The pilot bearing should be installed correctly to avoid any issues. During normal use, expect a moderate to heavy pedal effort, and the aggressive engagement might take a bit of getting used to. You'll notice that shifting is fast, which is great for high - performance driving. Remember, this clutch kit is designed for high - horsepower street cars or race use. Avoid using it in low - power, daily - driver scenarios where its full potential won't be utilized. Maintenance: Keep an eye on the clutch's performance. If you notice any unusual noises or a change in pedal feel, it could be a sign that the clutch needs inspection. There's no need for complex maintenance, but it's a good idea to have it checked by a professional periodically, especially if you use your vehicle for racing. Since the ACT clutch kit isn't compatible with the revised 240mm OEM components in some 2018 - onwards Subaru models, always double - check your vehicle's VIN if you're unsure about compatibility.
