Alright, gearheads, let’s talk about the ACT HD-M/Race Rigid 6 Pad Kit, model SB10-HDR6. If you’re looking to step up your clutch game, this is where it’s at. This kit features ACT's Heavy Duty pressure plate, which is a favorite among folks who know their stuff. The diaphragm design here isn’t just for show; it cranks up the clamp load, cuts down on deflection, and helps your clutch last longer. Seriously, it’s been through a four-stage heat-treating process, so you know it’s built to perform.
Now, let’s get into the nitty-gritty. The pressure plate is stamped with precision, giving it that extra rigidity and consistency you want when you’re pushing your ride to the limit. The 6-pad rigid race discs are crafted from high-quality ceramic friction materials, ensuring that when you slam those gears, they hold up. Plus, the chrome-moly hub is heat-treated, making it tough enough to handle whatever you throw at it.
This kit isn’t just about durability; it’s designed for speed. The lightweight, rigid setup means quicker shifts and a smoother experience overall. Just a heads up, though—the engagement can be a bit harsher, but that’s part of the trade-off for faster shifting. If you’re running a larger clutch size, this 6-pad disc is a solid choice since it can handle more heat without breaking a sweat.
And let’s not overlook the Monoloc feature. This one-piece upgrade replaces the standard two-piece wedge collar and wire ring found in pull-type clutches. The spring tension on the segmented retaining ring is spot-on, ensuring everything stays aligned perfectly, no matter how wild your driving gets. Plus, it’s made from hardened chrome-moly steel, so you can count on it to last.
