Hays has announced the expansion of its already expansive line of tried-and-true steel flywheels, which now supports 1969-’78 Big Block Fords, 1986-’92 Small Block Chevys, and late-model Big Block Chevys with steel cranks.

CNC-machined from 1045 billet steel that withstands the high-RPM demands of competition use, these all-new flywheels are ideal for today’s high-horsepower street, off-road, and race engines. Each one is CAD-designed for maximum performance and durability, SFI-certified to meet spec 1.1, and available for internal, external, and zero (neutral) balanced applications.

CNC machined from billet 6061-T6 aluminum, Hays aluminum flywheels are a great way to shave some weight off the drivetrain of your vehicle. Hays aluminum flywheels feature heat treated steel ring gears and a replaceable 1045 steel friction surface that is attached with high-grade fasteners.
