This is a brand new Exedy Stage 1Organic Heavy Duty Clutch for the 04 - 08 Subaru Impreza WRX STi 2.5L. Thisclutch is the Heavy Duty variant, which increases the wheel torquecapabilities to 402, over the standard Stage 1 Organic Clutch's 321.

EXEDYorganic 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 preferred clutch for street and light horsepower track use. Driveability is similar to the stock clutch. Pedal efforts will be slightly higher because of the higher clamp loads. All of Exedy's clutch discs have spring center dampers to reduce drivetrain shock.

Perfect as a replacement clutch if you have modified your vehicle's power output.

Includes alignment tool and throw out bearing.
