About Hays

Drag racing's biggest stars have relied on Hays since SEMA Hall of Famer Bill Hays decided back in 1958 that there had to be a way to build a clutch that could stand up to racing's unimaginable power and torque. "Big Daddy" Don Garlits, Tom "the Mongoose" McEwen, and countless icons of the sport went to just one place for their clutches -- Hays. Now part of Holley Performance, Hays continues to expand into all forms of driveline products for both automatic and manual transmissions. Hays offers complete clutch kits and torque converters for an infinite number of high-performance applications, pressure plates for precise gear changes, clutch discs for smooth, chatter-free engagement, and flywheels and flexplates ideal for today's vehicles.
