If you?re looking to upgrade your clutch game, the Advanced Clutch HD/Race Sprung 4 Pad Kit TC7-HDG4 is where it?s at. This kit features ACT's Heavy Duty pressure plate, which is a solid choice for anyone who wants to crank up their performance without sacrificing reliability. The diaphragm design in these plates is something special?it boosts clamp load and minimizes deflection, which means your clutch can take a beating and keep on kicking. Plus, each diaphragm goes through a four-stage heat-treating process that really sets it apart in terms of durability.
Now, let?s talk about the 4-pad spring-centered race disc. This isn?t just any disc; it?s engineered to dampen torsional vibrations, making your ride quieter while still being tough enough to handle the rough stuff. The springs are supported by wraparound spring windows and thicker retainer stampings, which means less stress and more strength where it counts. Sure, the engagement might feel a bit harsher, but that just means quicker shifts, and who doesn?t want that?
This kit is perfect for smaller engines, with a clutch disc diameter of 9.3 inches (or 236 mm, if you?re into metric). It?s built for those who push their machines to the limit?think high horsepower street or race applications. And don?t worry about it falling apart on you; every component is 100% clamp load tested and dynamically balanced to ensure smooth performance at high RPMs.
Installation is straightforward, and if you need a hand, just check out the instructions here. Here?s a quick rundown of what you can expect:
