If you're looking to up your clutch game, the ACT HD/Race Sprung 4 Pad Kit TC5-HDG4 is where it’s at. This kit features ACT’s go-to Heavy Duty pressure plate, which is kind of a big deal in the performance world. Why? Because it’s built with a unique diaphragm design that cranks up the clamp load, minimizes deflection, and helps your clutch last longer. Seriously, these diaphragms go through a four-stage heat-treating process, so you know they’re tough. The precision cover stampings on the pressure plate add an extra layer of rigidity and consistency, which is crucial when you’re pushing your vehicle to its limits.

The real star here is the 4-pad spring-centered race disc. It’s designed to dampen torsional vibrations, which means you’ll enjoy a quieter ride even when you’re really pushing it. And let’s be honest, this disc doesn’t mess around—it’s built to withstand some serious abuse. The wraparound spring windows and beefier retainer stampings on the ACT spring retainers mean you’re getting solid support that reduces stress and boosts reliability. Just know that while the engagement is a bit harsher, you’ll notice quicker shifts, which is a huge plus on the track or the street.

Now, if you’re curious about the nitty-gritty, here are some specs that might help you decide:

• Clutch Disc Diameter: 8.8 inches (224 mm)
• Torque Capacity: 355 ft/lbs—definitely a step up from stock
• Input Spline Quantity: 21
• Input Shaft Diameter: 1.125 inches
• Disc Material: Ceramic for high heat tolerance
• Weight: 14.5 lbs

This kit is perfect for those running high horsepower setups, whether you're tearing up the streets or hitting the track. Just keep in mind that it’s designed for light to moderate pedal effort, so it strikes a good balance between daily drivability and performance. You might experience some mild gear rattle, but that’s just part of the fun!

Installation Notes: If you’re planning to install it yourself, you can find the instructions here. Just a heads up, the kit doesn’t come with everything—like the clutch master cylinder, flywheel, or pressure plate bolts—but it does include grease and an alignment tool, which is nice.

So if you’ve got a Toyota 4Runner (1984-1988), Toyota Celica (1977-1985), Toyota Pickup (1978-1988), or Toyota Van (1984-1988), this kit is definitely worth a look. It’s built for those who want performance without compromising on reliability. Trust me, you won’t regret it.
