    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 GM 1997-up 4.8L, 5.3L, 5.7L & 6.0L LS engines with 6-bolt crankshaft flange, including 2010-15 Camaro with the L99 engine. Features include high tensile strength steel construction to resist elongation and cracking, 10.75 and 11.06-inch converter mounting locations, 168 tooth ring gear with double-sided welds for added strength and comes with SFI 29.1 safety certification ensuring the ultimate in safety and performance. The assembly is finished with Zinc plating and 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. Note: Will not fit 1999-00 6.0L applications with 0.400 inch extended crank flange/flat flexplate or 1999-00 4.8L engines that originally came with a manual transmission. A flexplate spacer is required for retrofitting Non-LS era transmissions to LS engines.
