This Hays SFI Certified flexplate gives you the perfect way to connect a Gen III Hemi to a 727, 904, A500, or A518 transmission without the use of a crankshaft spacer to get proper engine-to-transmission alignment. This allows you to use a stock-type torque converter with an attached ring gear. Our flexplate is constructed of 0.105" thick Grade 80 steel for maximum strength and is designed to handle the stress of high-stall torque converters and high horsepower engines. Features a zinc-dichromate plated finish to resist corrosion and SFI certified under specification 29.1.
