Overview:

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.

  • Connects Gen III Hemi to 727, 904, A500, A518 transmission
  • Made from 0.105” Grade 80 steel to resist cracking near crankshaft flange
