This is the clutch you need for all your horsepower! We now run this clutch in our KPower Turbo K24Z race car and it does not disappoint. With a torque rating of 671ft-lbs and a carbon semi-metallic full-faced disc, you can be sure this will take the abuse of anything your turbo K engine can throw at it! Pedal effort is moderate and engagement is smooth. All clutches ship with a pressure plate and clutch disc along with a clutch alignment tool. You have the option to add a release bearing or pilot bearing depending on your application. Our flywheels include a pre-installed pilot bearing, and K series to ZF 5-speed users use our supplied release bearing, so an OEM release bearing is not needed. BP engine users will need to add a release bearing.  Please note that Spec clutches are made to order and can take up to 2-4 weeks to be finished.
