Spec Clutch SC423Y Stage 3 Performance Clutch Kit - Carbon Semi-Metallic 6-Puck

The Spec Clutch SC423Y Stage 3 Clutch Kit is the ultimate street/strip solution for heavily modified, high-powered engines demanding both aggressive torque capacity and everyday drivability. Rated to handle up to 762 ft-lbs of torque, this kit delivers sharp, confident engagement without sacrificing comfortable pedal feel — making it equally at home on a daily driver as on the drag strip or road course.
