Centerforce is proud to introduce this DFX clutch assembly for the 1999 to 2004 Ford 7.3L Diesel Super Duty. The new DFX line is the latest series of extreme performance clutches from Centerforce designed as a direct bolt in for perfect fit and function. DFX scores big, not only with holding-capacity and strength, but also provides some of the best drivability for your high torque application. DFX performance clutch systems utilize a patented Centrifugal Weight System for increased holding capacity with RPM and Nodular Iron pressure plate rings and reinforcements designed to help prevent drive strap breakage and increase safety. The paddle or button style disc has been through constant testing of different friction materials and hub designs to bring the best possible combination available to you.
