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 1998-up 4.8L, 5.3L, 5.7L & 6.0L LS engines with 6-bolt crankshaft flange, including 2010-15 Camaro with 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 insuring the ultimate in safety and performance. The assembly is finished with a 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.
