If you're looking to up your clutch game, the ACT HD/Race Sprung 4 Pad Kit (HW2-HDG4) is where it’s at. This kit features ACT's Heavy Duty pressure plate, which is a favorite among performance enthusiasts for a reason. The unique diaphragm design really cranks up the clamp load, cuts down on deflection, and helps your clutch last longer—something we all appreciate when we're pushing our rides to the limit.

What’s cool about these pressure plates is that they go through a four-stage heat-treating process. This means you get top-notch performance that can handle the heat of spirited driving or racing. Plus, the precision cover stampings make sure everything stays rigid and consistent, which is crucial for reliable performance.

Now, let’s talk about the 4-pad spring-centered race disc. This bad boy is designed to dampen torsional vibrations, so you get a quieter operation even when you’re really laying into the throttle. And trust me, it’s built to survive some serious abuse. The wraparound spring windows and beefier retainer stampings mean you get better support and strength, which translates to reliability when you need it most. Just a heads-up though: engagement is a bit harsher, but that just means quicker shifts, which is what we all want when we're racing or cruising hard.

This kit is perfect for smaller disc sizes and engines, making it a solid choice for those who like a little extra bite in their performance. It’s designed for light to moderate pedal effort, so you won't be wearing out your leg during those long drives, but you’ll definitely feel the aggressive engagement.
