Hays carries an extensive selection of heavy-duty flexplates for high-performance and competition Chevy, Ford, and Pontiac engines. Boasting a thicker-than-stock steel plate, these more robust flexplates can handle the force generated under higher torque and RPM conditions—which can crack the crankshaft hubs of factory stock plates.

Welded ring gears and dual bolt patterns add security and the flexibility to adapt to a variety of transmission-style torque converters. Hays flexplates are finished off with corrosion-resistant zinc-dichromate and are SFI certified under specification 29.1.

  • Most feature a zinc dichromate finish for superior corrosion resistance and good looks
  • Heavy-duty design leverages thicker steel plate to withstand the stress of high-stall converters and high-RPM engines
