As performance levels increase, an O.E. style flexplate just won't cut it and a stronger option is a necessity to prevent transmission and/or converter failure. B&M has you covered with our high performance flexplate designed for 1971-1992 Chrysler, Dodge and Plymouth 360ci (externally balanced) V8 engines with A904 transmission. Features include high tensile strength steel construction to resist elongation and cracking, 10.00-inch bolt pattern and comes with SFI 29.1 safety certification insuring the ultimate in safety and performance. 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.
