Alright, gearheads, let’s talk about the ACT NS4-HDR6 HD/Race Rigid 6 Pad Kit. If you’re serious about your clutch setup, this is the kind of kit that’s going to make your heart race. We’re talking about ACT’s Heavy Duty pressure plate here, which is a fan favorite for good reason. It’s got this unique diaphragm design that cranks up the clamp load, cuts down on deflection, and helps your clutch last longer. Seriously, these diaphragms go through a four-stage heat-treating process, so you know they’re built to take a beating.

Now, let’s get into the nitty-gritty. The pressure plates are engineered with precision cover stampings, giving you that extra rigidity and consistency you need when you’re pushing your ride to the limit. And those 6-pad rigid race discs? They’re made from top-notch ceramic friction materials. The chrome-moly hub is heat-treated too, meaning it’s tough as nails. This lightweight, rigid design means you can shift quicker without any hiccups.

Just a heads up, though: the engagement is a bit harsher with this setup, but you’ll notice shifts happening faster than ever. This kit is really geared towards those who want to absorb more heat, especially if you’re running larger clutch sizes. It’s definitely race-focused, so if you’re hitting the track, this is what you want.

  • Everything’s carefully engineered and balanced, using select ceramic materials that can handle the heat and deliver max performance.
