Manufactured from certified billet steel, these flywheels will not break under the stress of high RPM or the punishment of racing. Varying from 25 to 50 pounds based on application, most Hays flywheels are drilled with both the Borg & Beck and Long clutch patterns. All are precision-balanced to either Detroit (external) or neutral (internal) specifications (1.1 SFI-certified).

Transfer Power to the Wheels Through a Performance Flywheel

Hays Performance Flywheels are popular amongst street and race enthusiasts for their durability and strength. Each flywheel is built with certified billet materials to ensure non-breakage under the stress of high engine RPMs. They are precision balanced on both internal and external versions for peak performance output.
