When your engine puts out high performance, you need a Clutch Kit that can handle it properly. All ACT Clutch Kits provide a generous increase in clamp load which directly increases torque capacity. ACT Clutch kits are offered in a number of configurations. There is sure to be one developed specifically for your vehicle. ACT HDG4 Clutch Kits use a Heavy Duty Pressure Plate superior to the stock pressure plate. The clutch disk is made of a copper ceramic material which holds approximately 27% more torque than an organic lining.
