EXEDY Stage 1 Organic Racing Clutches only use premium friction materials that are resistant to slippage and burst. Increased clamp loads give the necessary capacity to handle modified engines. This is the ideal clutch for street and light horsepower track use. Drivability is similar to the stock clutch. Pedal efforts will be slightly higher because of the higher clamp loads. All of our Stage 1 clutch discs have spring center dampers to reduce drivetrain shock and provide smooth clutch engagement.
