The assembly is then Zinc plated and treated with a Chromate Conversion Coating for added corrosion resistance and durability. B&M SFI approved flexplates are ideal for extreme duty race applications as well as street cars, tow vehicles or other vehicles needing the added protection and toughness that B&M has been delivering since 1953.
