Midway Industries Centerforce division is proud to be recognized as the leading manufacturer of performance clutch and pressure plate systems in the United States. Centerforce s reputation as the clutch system of choice stretches back to the early 1980 s when legendary Hot Roder and SEMA Hall of Fame member Bill Hays sought to cure problems with existing designs while developing a competition-rated clutch/pressure plate system suitable for use with non-asbestos friction facings. Bill s remarkable innovation was soon patented as the Centerforce Weighted Clutch System. The Centerforce design applies proven principles of weight and centrifugal force to develop the increased clamping loads modern clutch facings require while maintaining easy pedal effort and eliminating old-style diaphragm over-center problems disastrous to high-performance engines. Continuous development and improvement of product offerings is reflected in the unique features of the Centerforce clutch line being protected under nine separate (9) U.S. patents. Today Centerforce has over 1700 different non-asbestos clutch/pressure plate applications available to the automotive enthusiast.
