If you’re looking to get serious about your clutch game, the Advanced Clutch Heavy Duty Pressure Plate SB018 is definitely worth a look. This isn't just any pressure plate; it's crafted by ACT and features an exclusive diaphragm design that cranks up the clamp load while minimizing deflection. What does that mean for you? Essentially, it’s all about maximizing clutch life and performance. Each diaphragm goes through a four-stage heat-treating process, so you know it’s built to last, even under pressure.
One of the standout features of the ACT pressure plates is their precision cover stampings. This isn’t just for show; it adds a level of rigidity and consistency that you can really feel when you’re behind the wheel. With an increase in clamp load by 20 to 50 percent, you’re looking at a serious upgrade, especially if you’re running a street or race disc. Plus, the Monoloc system is a game-changer. It replaces the standard two-piece wedge collar and wire ring found in pull-type clutches with a one-piece design that’s direct and easy to install.
The spring tension on the segmented retaining ring is meticulously calculated and tested, ensuring optimal performance. It provides uniform loading on the bearing and pressure plate, which means you won’t have to worry about alignment issues, even if you’ve made some modifications to your ride. Built from hardened chrome-moly steel, the Monoloc is designed for durability, giving you years of reliable service.
Installation is straightforward, too:
