| |
Hays billet steel flywheels are manufactured from certified materials that will not break up under the severe punishment of racing, including stresses from high rpm. They are available for a wide range of popular small block and big block applications, and most are drilled for both Borg & Beck and Long-style clutch assemblies. All of these flywheels are balanced, either to neutral or external-balance specs, and they're SFI-approved.
Warranty
Performance and SFI-approved flywheels must be used with performance clutch discs only. Use of a stock-style clutch disk with a performance flywheel will often result in insufficient operating clearance between the disc hub and flywheel bolts.
