If you're looking to step up your game with a clutch that can handle serious power, the Advanced Clutch Mod-Twin 10.5 XT Sprung Street Kit might just be what you need. This isn’t just another part; it’s a carefully crafted piece of engineering designed for high-powered street machines, particularly the Ford Mustang GT from 2018 to 2023. What sets this kit apart is how it combines a soft, progressive engagement with a durable build, making it perfect for both daily driving and spirited weekend runs.

One of the standout features is the dual organic friction surfaces. This means you get a solid grip without sacrificing that smooth pedal feel you want on the street. The sprung Mono-Drive hub assembly is built tough, and the diaphragm springs go through a four-stage heat treat process. This not only helps with a consistent pedal feel but also ensures the clutch can handle the heat when you’re pushing it hard. Plus, the steel-backed friction plates are made from high-quality organic materials, giving you a stable friction coefficient that translates to longer clutch life.

Installation is straightforward, and you’ll get everything you need in the kit: a CNC-machined flywheel, pressure plate cover, and even an alignment tool. Just keep in mind, it’s a 10.5-inch clutch disc with a 23-spline input shaft, so make sure your setup matches. The torque capacity is impressive too—986 ft/lbs, which is a solid bump over OE specs. That’s a lot of muscle, especially if you’re looking to push your Mustang to its limits.

Now, if you’re worried about driveline shock, this setup has you covered. The design helps extend the input shaft life and minimizes torsional vibrations, which can be a real headache with less robust clutches. And if you ever need to replace the discs, don’t sweat it; the Mod-Twin clutches are fully rebuildable, making maintenance a breeze.

Features:

  • Soft, progressive engagement with light pedal effort for smooth shifting.
  • Forged aluminum cover and premium materials ensure durability.
  • Designed for street or street/strip use, so it’s versatile.
  • All components are clamp load tested and SFI certified.

Specifications:

  • Clutch Disc Diameter: 10.5 in (267 mm)
  • Input Spline Quantity: 23
  • Input Shaft Diameter: 1 in
  • Torque Capacity: 986 ft/lbs
  • Product Weight: 45.4 lbs

So, if you’re ready to take your Mustang’s performance up a notch, this clutch kit is definitely worth considering. It’s built for the long haul and ready to handle whatever you throw at it.
