This ACT clutch kit (SB9 - XTG4) is a perfect fit for 2002 - 2005 Subaru WRX, 2004 - 2005 Subaru Forester XT, and 2004 - 2005 Subaru Baja Turbo. It features a sprung, 4 - pad race clutch disc paired with an Xtreme pressure plate. You'll experience moderate to heavy pedal effort with an aggressive engagement, and it can handle up to 654 ft/lbs of torque. Ideal for high - horsepower street or race use. The ACT Xtreme pressure plates use an exclusive diaphragm design to boost clamp load, reduce deflection, and extend clutch life. All diaphragms go through a four - stage heat - treating process. The precision cover stampings offer rigidity and consistency. The 4 - pad spring - centered race disc dampens torsional vibrations for quiet operation and resists failure in harsh conditions. The spring retainers provide strong support and increase reliability. With this disc, engagement is harsher but shifting is faster, making it great for smaller engines. The Monoloc is a one - piece replacement that ensures proper alignment and has a long service life. The kit includes a 4 - pad sprung race disc, an Xtreme pressure plate, an alignment tool, a pilot bearing, and a release bearing. It's 100% clamp load tested and dynamically computer balanced, and comes with ACT's patented Monoloc.
Using this ACT clutch kit is straightforward. First, make sure your vehicle is turned off and safely supported. Remove the old clutch components and install the new ones in the following order: pilot bearing, 4 - pad sprung race disc, Xtreme pressure plate, and then the release bearing. Use the alignment tool to ensure proper alignment. When you're driving, expect a moderate to heavy pedal effort and an aggressive engagement. Be aware that there might be a bit of gear rattle, similar to an OE or mild setup, but this won't affect performance. For high - horsepower street or race use, this clutch kit is a great choice. When it comes to maintenance, regularly check the clutch for signs of wear, like slipping or unusual noises. If you notice any issues, it's best to have it inspected by a professional. Also, keep the clutch clean to prevent dirt and debris from causing damage. With proper use and maintenance, this clutch kit, including the Monoloc, will serve you well for a long time.
