Hays heavy-duty flexplates for Gen III Hemi engines are constructed of a thicker than stock steel plate, enabling them to withstand the stress of high-stall torque converters and todays high-RPM engines. Designed to work with NAG1, ZF 8HP70, and 8HP90 transmissions. 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 are supplied with a ring gear that is securely welded in place. All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and are SFI certified under specification 29.1.
