ACT HD/Race Sprung 6 Pad Kit Ford | Mercury 1986-2001 - FM1-HDG6

If you're looking to step up your clutch game, the ACT FM1-HDG6 Advanced Clutch HD/Race Sprung 6 Pad Kit is a solid choice. This kit features ACT's go-to Heavy Duty pressure plate, designed with an exclusive diaphragm setup that cranks up the clamp load while minimizing deflection. What does that mean for you? More grip, less slippage, and a longer clutch life. Seriously, they’ve put this through a four-stage heat-treating process that really makes a difference in performance.

The pressure plate itself is no joke—it’s got precision cover stampings that give it the rigidity you want when you're pushing your car to its limits. And let’s talk about the 6-pad, spring-centered race disc. This isn’t just any disc; it’s engineered to dampen those torsional vibrations that can mess with your ride. You can push it hard without worrying about it failing under pressure. Just keep in mind, with this setup, engagement is a bit harsher, but you’ll notice that shifting is quicker and snappier. It’s designed for larger clutch sizes, which means it can take the heat and keep on performing.

Now, for those of you who are into the nitty-gritty, here’s what you can expect:

  • Light to moderate pedal effort, so you won’t feel like you’re wrestling with your car.
  • Moderate friction life, thanks to ACT's unique diaphragm design that extends longevity.
  • High-performance ceramic friction materials that can handle the heat—perfect for street or race applications.
  • Every component is clamp load tested and dynamically balanced, ensuring smooth operation at high RPMs.

As for the specs, here’s what you need to know:

  • Clutch Disc Diameter: 10.5 in (or 266 mm)
  • Disc Material: Ceramic, built for high heat tolerance
  • Torque Capacity: A solid 620 ft/lbs, which is a nice bump over OE.
  • Input Spline Quantity: 10
  • Input Shaft Diameter: 1.0625 in
  • Product Weight: 22.1 lbs

Oh, and just a heads-up: this kit doesn’t come with a clutch master cylinder or pressure plate bolts, but it does include grease, a release bearing, and a pilot bearing. Plus, you’ll get an alignment tool to make installation a bit easier.

This kit fits a range of Ford Mustangs from 1986 to 2001, including the Mustang GT and SVT Cobra, as well as the Mercury Capri from 1986. So, if you're ready to upgrade your clutch setup, this is definitely worth considering.
