The ACT HD/Performance Street sprung clutch kit for the 2005 Chevrolet Cobalt uses ACT's Heavy Duty diaphragm pressure plate with a Performance Street sprung disc to deliver stronger clamp and reliable street drivability. The pressure plate's diaphragm undergoes a four-stage heat treatment and precision cover stamping for consistent rigidity while the street disc's copper-rich organic material and steel-backed lining improve heat transfer and burst resistance.
