So, you’re looking to amp up your clutch game? The ACT Heavy Duty/Performance Street Sprung Kit (JP6-HDSS) is where it’s at. This setup isn’t just about numbers; it’s built for real-world driving, whether you’re hitting the streets or taking on some off-road trails. The heavy-duty pressure plate is a standout feature, designed to handle a solid torque capacity of 479 ft/lbs—32% more than stock. That means you’re getting a clutch that can really take a beating without falling apart.
What I love about this kit is how it balances performance with drivability. You get a light to moderate pedal effort, which means you won’t feel like you’re wrestling with your car every time you shift. The engagement is smooth and positive, so you can focus on enjoying the drive instead of worrying about your clutch. Plus, it’s engineered to minimize gear rattle, making your ride a lot more pleasant.
The diaphragm design is a game changer. It cranks up the clamp load while reducing deflection, which extends the life of the clutch. ACT puts their diaphragms through a four-stage heat-treating process, so you know they’re built to last. And let’s not forget about the premium organic friction materials—they’re steel-backed for extra durability and improved heat tolerance. That means less fade and better performance when you really need it.
Now, if you’re curious about the specs, here’s the rundown: the clutch disc diameter is 11 inches (or 280 mm), and it has a 21-spline input. The kit comes with everything you need, including the Pro-Mass flywheel and all the necessary bolts. Just a heads up, though: it doesn’t include a clutch master or slave cylinder, so you’ll need to sort that out separately.
For installation, you can find detailed instructions here. Overall, if you’re driving a 2020-2024 Jeep Gladiator or a 2018-2025 Jeep Wrangler, this kit is a solid investment for anyone looking to up their clutch performance without compromising comfort. Get ready to feel the difference!
