This ACT SB9 - HDG4 clutch kit 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 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 555 ft/lbs of torque. Ideal for high - horsepower street cars or race use. The heavy - duty pressure plates use an exclusive diaphragm design. They increase clamp load, reduce deflection, and maximize clutch life. All diaphragms go through a four - stage heat - treating process for top - notch performance. The precision cover stampings provide rigidity and consistency. The 4 - pad spring - centered race disc has a spring - center construction to damp torsional vibrations for quiet operation and resist failure in tough conditions. The spring retainers support the springs, reduce stress, and boost strength and reliability. With this disc, engagement is harsher but shifting is faster, making it great for smaller engines. The Monoloc is a one - piece upgrade to the standard two - piece in pull - type clutches. Its spring tension is carefully calculated for optimal performance, providing uniform loading and proper alignment. It's made of hardened Chrome - moly steel for long - lasting service. Included in the kit are a 4 - pad sprung race disc, a heavy - duty pressure plate, an alignment tool, a pilot bearing, and a release bearing.
Using this ACT clutch kit is straightforward. First, make sure your vehicle is the right model and year (2002 - 2005 Subaru WRX, 2004 - 2005 Subaru Forester XT, or 2004 - 2005 Subaru Baja Turbo). Then, install the included 4 - pad sprung race disc, heavy - duty pressure plate, alignment tool, pilot bearing, and release bearing following the standard installation procedures for your car. When driving, expect a light to moderate pedal effort and an aggressive engagement. You may notice increased gear rattle, but it's normal for this high - performance clutch. During hard shifts, you'll feel confident. As for maintenance, keep an eye on the clutch performance. If you feel a change in pedal feel or engagement, it might be time for an inspection. Also, make sure the Monoloc and other components are in good condition. This clutch kit is built to last, especially with the hardened Chrome - moly steel Monoloc, but regular checks will ensure it serves you well for years.
