If you're looking to step up your clutch game, the ACT HD-O/Perf Street Sprung Kit T43-HDSS is where it’s at. This isn’t just another aftermarket part; it’s built with some serious thought and engineering. The Heavy Duty pressure plate is a standout feature, and the street disc is one of ACT's best sellers for a reason. You get a solid torque capacity—285 ft/lbs to be exact—so whether you’re tearing up the streets or hitting the trails, this kit has your back. The smooth, precise feel is a game changer, making it easy to engage without feeling like you’re wrestling with the pedal.

One of the things I love about this kit is ACT’s exclusive diaphragm design. It ramps up the clamp load while keeping deflection to a minimum, which means you can expect longer clutch life. They really put this thing through the wringer with a four-stage heat-treating process that ensures it can handle whatever you throw at it. And let’s be honest, when you’re pushing your rig, you want a clutch that can keep up without giving you that annoying gear rattle.

The pressure plate is engineered for rigidity and consistency, so you won’t be worrying about it warping under pressure. Plus, the precision-machined castings do a great job of absorbing heat, which is crucial when you’re pushing your vehicle to its limits. The street disc is made from premium organic friction materials that not only resist wear but also improve heat capacity, thanks to a steel backing that adds some serious durability.

Now, if you’re thinking about installation, you’ll find everything you need in the box, including grease and an alignment tool. Just keep in mind that while the clutch master cylinder and some other bits aren’t included, the release bearing and pilot bearing are there, so you’re not left hanging.

This kit is perfect for both street and race use, and it’s been 100% clamp load tested and dynamically balanced to ensure smooth operation, even at high RPMs. If you’re ready to upgrade your Toyota 4Runner (1987-1995) or Toyota Pickup (1987-1995), this is the way to go.
