Exedy Stage 1 - This is the preferred clutch for street and light horsepower track use. Driveability is similar to the stock clutch with smooth engagement characteristics. Pedal efforts will be slightly higher due to the approx 25% higher clamp loads. The clutch disc is equipped with spring center dampers to reduce drivetrain shock. Rated wheel torque - 237 ft/lbs.
Exedy Stage 1 HD – The Heavy Duty (HD) clutch package features the exact same disc as the Stage 1 package, but this kit is equipped with a more aggressive pressure plate for use with higher horsepower applications. This pressure plate offers higher clamping forces and pedal efforts will be greater due to the approx. 40% higher clamping loads as compared with the stock pressure plate.
