Billet Steel Flywheels -
Hays Steel Flywheels are manufactured from certified billet material that will not break up under the stress of high RPM and severe punishment of racing. Available in weights up to 50 pounds for specialized application. Most Hays Flywheels are drilled with both the Borg & Beck and Long-Style clutch pattern. All flywheels are precision balanced to either neutral (internal) or Detroit (external) specifications 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.
