American Hot Rod Solutions high performance flexplates are manufactured from stamped, cold rolled, and non-re-sulfurized carbon steel plate. The 5/32" thickness of the stamped plate is much heavier than OEMs for superior strength(25% Thicker in most cases). The heavy gauge steel plate is double Argon gas welded to gear ring. The high manganese carbon steel gear ring is machined by CNC machine centers for superior wear resistance for engines frequently kicked on and off. All American Hot Rod Solutions flexplates are tested to 12,500 RPM for explosion proof construction, in compliance with SFI 29.1 specification. Surface is yellow dichromate finished for rust resistance and appearance. These SFI rated Flexplates are ready for all the punishment your motor can deliver. Bolt right on no modifications needed (except if using a LT1 Transmission bolted to a LS1 Engine). Compare to Hayes and B&M prices, don't over pay at your local parts store either!!!
Curt explains the differences between flywheels and flex plates. The main difference is that flywheels are for manual transmissions and flex plates are for automatic transmission. The flex plate is designed to "flex" in order to allow the torque converter to spin at such a high speed and not cause heavy vibrations.
