BD’s 6r140 Flex Plate is CNC machined out of 1.5x thicker than stock quench and tempered 100,000psi steel. In-house machining incorporates an integrated counterweight which is then balanced to tighter tolerances than OE specifications. Black Oxide coated to resist corrosion. These units will fit any OEM or aftermarket torque converter and affordable enough to upgrade during a converter or transmission swap. The BD Flex Plate is a direct, bolt-in replacement for the stock unit. Great for racing, towing or stock use.
