This ACT Heavy Duty Pressure Plate (SB018) is a top - notch replacement part designed specifically for the original ACT SB9 Clutch Kit. It fits Subaru WRX from 2002 to 2005, Forester XT from 2004 to 2005, and Legacy GT Spec B from 2008 to 2009. Using an exclusive diaphragm design, it boosts the clamp load, reduces deflection, and significantly extends the clutch life. All diaphragms go through a four - stage heat - treating process for outstanding performance. The precision cover stampings of ACT pressure plates ensure rigidity and consistency. Compared to standard ones, ACT's Heavy Duty pressure plates can increase the clamp load by 20 to 50 percent. It's a great choice for both street and race discs. The Monoloc, a one - piece component, is a direct replacement or upgrade for the standard two - piece wedge collar and wire ring in pull - type clutches. Its segmented retaining ring's spring tension is carefully calculated and tested for optimal performance, providing uniform loading on the bearing and pressure plate to guarantee proper alignment, regardless of driver actions or vehicle modifications. Made of hardened chrome - moly steel, Monoloc offers long - lasting service. With light to moderate pedal effort, it gives you confidence during hard shifts and positive engagement. It's recommended for both street and race use. Every ACT pressure plate is 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability. It also comes with ACT's patented Monoloc and a limited retail warranty. Installation follows ACT's General Installation Instructions.
Using the ACT Heavy Duty Pressure Plate is quite straightforward. First, make sure your vehicle is the right model and year as specified in the fitment information, like Subaru WRX from 2002 - 2005, Forester XT from 2004 - 2005, or Legacy GT Spec B from 2008 - 2009. When installing, follow ACT's General Installation Instructions carefully. You'll notice a light to moderate pedal effort, which gives you a confident feeling during hard shifts and positive engagement. For street and race use, this pressure plate is a great choice. Just keep in mind that it's designed to replace parts from the original ACT SB9 Clutch Kit. When it comes to maintenance, since the diaphragms go through a four - stage heat - treating process and the Monoloc is made of hardened chrome - moly steel, they are quite durable. But still, you should regularly check the alignment of the bearing and pressure plate to make sure the Monoloc is working properly. If you make any vehicle modifications, the Monoloc will still keep things in proper alignment, but it's always a good idea to double - check. And remember, it comes with a limited retail warranty, so if you have any issues, you can reach out for support.
