This Hemi Flexplate is designed to work with Chrysler 904 & 727 torqueflite automatic transmissions and is perfect for engine swaps. The Flexplate is .035 in. thicker than stock and has a 29.1 SFI approval stamped into the face of the plate.
SFI 29.1 Rated Flexplates
Built to exceed OE specifications, JEGS die-stamped flexplates are made from Chromoly steel with a double-welded ring gear to prevent separation in high-RPM engines. Each drag racing flexplate has a zinc-dichromate finish applied to prevent degradation, then undergoes a final plate inspection and SFI certification testing to guarantee complete customer satisfaction.
