ACT 2010 Hyundai Genesis Coupe HD/Perf Street Sprung Clutch Kit
The ACT HY4-HDSS is a street clutch upgrade for the Hyundai Genesis Coupe 3.8 V6 with the six-speed manual. It pairs ACT's Heavy Duty pressure plate with its Performance Street sprung organic disc, and it is aimed at owners whose factory clutch is slipping, glazed or simply worn out, or who have added intake, exhaust and tuning and want more holding power without a race-clutch pedal. If you are searching for a Genesis Coupe 3.8 clutch that still drives like a daily car, this is the kit built for that job.
On the 3.8 V6 manual car the clutch clamps between the factory dual-mass flywheel and the pressure plate, passing engine torque to the transmission input shaft. ACT's Heavy Duty plate uses its own diaphragm design to raise clamp load and reduce deflection, so the disc grips harder without a big jump in pedal effort. The disc is a 250 mm sprung hub unit with a high-copper organic facing on a steel-backed lining, which sheds heat better than the stock disc and keeps the smooth engagement of organic material. ACT rates the kit at 405 ft-lb of torque capacity at the crank, 26 percent over the factory clutch. ACT describes the feel as light to moderate pedal effort with smooth, positive engagement. The kit contains the HY013 Heavy Duty pressure plate, the 3001605 Performance Street sprung disc and an AT23 alignment tool. It does not include a release bearing or pilot bearing, so plan to source those separately.
Run a slip check in fourth gear from low RPM at full throttle. If the tachometer climbs faster than the car accelerates, the disc is slipping. Grinding and hard shifting with no slip are more often a hydraulic problem: check the reservoir level and condition, look for a leak at the slave cylinder, and bleed the system before ordering a clutch. Our slipping diagnosis guide covers how to separate true slip from other faults, and the manual transmission repair cost guide helps you budget the job.
Our listing is titled for the 2010 Genesis Coupe. ACT's application chart lists the HY4-HDSS for the 2010-2012 Hyundai Genesis Coupe 3.8L V6, including the base, GT, Grand Touring, R-Spec and Track trims. It is not for the 2.0T four-cylinder cars or the 2013-up cars, which use different clutches. ACT designs this kit for use with the stock dual-mass flywheel. If your car has a swapped gearbox or an aftermarket flywheel already, send us your year and VIN and we will confirm before it ships. More clutch kits are in the rebuild kits category.
If the car makes much more power than a bolt-on V6, the HY4-HDG6 six-pad race kit uses the same Heavy Duty plate with a ceramic disc rated for far more torque, with a much more aggressive engagement.
