Hays Steel SFI Approved Flexplate - Chrysler Small Block and Big Block

Hays Steel SFI Approved Flexplate - Chrysler Small Block and Big Block

Hays heavy-duty flexplates for high performance and competition engines are constructed of a thicker than stock steel plate, enabling them to withstand the stress of high-stall torque converters and today's high-RPM engines. While factory stock plates tend to crack around the crankshaft hub when punished under high torque and RPM conditions, the thicker Hays Flexplate handles the force. These H.D. flexplates fit 904, 999, and 727 Torqueflite transmissions. All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and are SFI certified under specification 29.1.
