If you're looking to take your ride to the next level, the AI4-HDG4 Advanced Clutch HD/Race Sprung 4 Pad Kit is where it’s at. This isn’t just another clutch kit; it’s built with some serious thought and engineering. ACT’s Heavy Duty pressure plate is the star of the show here. They’ve got this exclusive diaphragm design that cranks up the clamp load while keeping deflection in check. What does that mean for you? More clutch life and better performance, plain and simple.
Now, let’s talk about the heat-treating process. ACT puts their diaphragms through a four-stage heat treatment that really boosts performance. You can feel the difference when you’re shifting gears. The precision cover stampings add a level of rigidity that you’ll appreciate, especially when you’re pushing your vehicle hard. And don’t get me started on the 4-pad spring-centered race disc. It’s designed to dampen those annoying torsional vibrations, so you get a quieter ride even when things get rough. Plus, it’s built to withstand some serious abuse, so you can trust it won’t let you down.
Sure, the engagement is a bit harsher, but that just means faster shifts. If you’re running a smaller engine, this disc is perfect since it’s tailored for smaller sizes. It’s a solid choice for anyone looking to up their horsepower game, whether you’re cruising on the street or hitting the track.
