ACT HD/Perf Street Sprung Kit Hyundai Genesis Coupe 2010-2012 - HY4-HDSS

If you've been on the hunt for a clutch kit that can really take a beating while still delivering smooth performance, the Advanced Clutch HD/Perf Street Sprung Kit HY4-HDSS might just be your new best friend. This kit is built around ACT's Heavy Duty pressure plate, which is basically the go-to option for folks who want durability without sacrificing feel. The diaphragm design here is pretty slick—it ramps up the clamp load while keeping deflection to a minimum, which means your clutch is gonna last longer and perform better under stress.

Now, let’s talk about the pressure plate. It’s heat-treated through a four-stage process, so you know it’s tough. The precision cover stampings add a nice touch of rigidity, ensuring everything stays consistent during those high RPM runs. Pair that with ACT's Performance Street disc, and you've got a setup that features premium organic materials mixed with high copper content. This combo not only improves heat transfer but also gives the disc a serious boost in burst strength and durability. Plus, with reduced marcel, you can expect quicker shifts—perfect for when you really want to get on it.

Installation? No sweat. You can find the instructions right here. Just a heads up, this kit has been engineered for both street and race use, so whether you’re hitting the track or just cruising around town, it’s got your back.

Features that stand out:

  • Light to moderate pedal effort makes it easy to engage, with just a hint of gear rattle for that race-ready feel.
  • Thanks to ACT's unique diaphragm design, you’re looking at a longer friction life.
  • Each component is carefully engineered and balanced, using top-notch organic friction materials to handle heat like a champ.
  • 100% clamp load tested and dynamically balanced, so you can trust it at high RPMs.
