Description: Lightweight, high-strength alloy. Are you running a serious, lightweight, big-cubic-inch drag car? Hays et aluminum flywheels are popular with your competition. Shouldn't you have one? They're machined from high-strength, lightweight, forged 7075 T-6 et aluminum, which exceeds all material specs for strength and centrifugal distortion. They feature replaceable bronze or steel friction surfaces, and most are drilled for Borg & Beck and Long-type clutch assemblies. Ring gears are secured via welded tabs that are riveted to the flywheel to prevent spinning. Both neutral and external-balance flywheels are available, and both types are SFI-approved. (minimize)
