Overview

Constructed of thicker than stock steel plate to withstand the stress of high stall speed converters and high RPM engine Securely welded ring gear with dual bolt pattern for use with either Powerglide or Turbo-Hydromatic transmission Meets SFI specification 29.1 for racing 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 high-RPM engines.

All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and are SFI certified under specification 29.1.
