If you're on the hunt for a clutch kit that can handle both daily driving and the occasional spirited romp, look no further than the ACT SZ1-HDMM kit. This thing is built tough, featuring ACT's Heavy Duty pressure plate, which is kind of the bread and butter for performance enthusiasts. The exclusive diaphragm design cranks up the clamp load, cuts down on deflection, and really stretches the life of the clutch. Each diaphragm goes through a four-stage heat-treating process, so you know it?s ready to take a beating.
The pressure plate itself is no slouch; it?s got precision cover stampings that lend it some serious rigidity and consistency. When you pair that with the modified spring-centered street discs, you?re looking at a setup that?s got premium organic friction material packed with high copper content. What does that mean for you? Better heat transfer and durability, plain and simple. Plus, these discs are tweaked with reduced marcel, which means quicker shifts. You?ll notice the difference when you?re zipping through the gears.
Now, let's talk about those heavy-duty torsional dampening springs. They?re beefier than what you?d find in standard setups, and they come in just the right sizes and spring rates to match your application. This translates to smooth engagement and a quiet ride, all while boosting strength and reliability. Whether you?re cruising around town or hitting the track, this kit has your back.
