Hays Billet Aluminum Flywheels

Hays Billet Aluminum Flywheels -
Hays , the favorite choice of many road racers, are also popular with the serious drag racer running a light car and large cubic inch motor. Machined from 7075 T-6 forged billet aluminum, this high strength alloy surpasses all material specs as to strength and centrifugal distortion.

All Hays Billet Aluminum Flywheels feature a replaceable steel or bronze heat shield friction surface and are drilled to accept either the Borg & Beck or Long-Style clutch pattern. The ring gear is securely mounted with welded tabs that are riveted to the flywheel to prevent spinning. Hays Billet Aluminum Flywheels are supplied in neutral (internal) balance or Detroit (external) balance and are certified under SFI spec 1.1.

Technical Tip: Aluminum vs Steel

Aluminum flywheels with their lighter weight, are typically used in oval track and road race applications and are also popular in high-horsepower, light weight drag cars.

These vehicles rely on engine horsepower to drive the wheels. Steel flywheels are used in applications that require additional engine torque for performance. A heavier flywheel can help acceleration from a standing start and keep the engine's RPM and power up through shifting. These are characteristics needed in street, most drag race and other high-torque applications such as tractor pulling.
