The ACT Xtreme pressure plate has a radical increase in clamp load developed from a single specially designed diaphragm. ACT employs several secrets (just good engineering) to maximize load and reduce flex. The result is maximum torque capacity and long life, while maintaining good release clearance for fast, clean shifting. This kit comes with an ACT Street Disc which is designed for smooth engagement, quiet operation and improved durability using only the best organic, spring center designs. This kit also comes with a throwout bearing and alignment tool.
