Product Details

The B&M SFI Certified Steel Flexplate is an automatic transmission flexplate. It connects the engine crankshaft to the torque converter and transfers engine power to the transmission. It is built for high-performance street, strip and racing use, where a stock flexplate may not hold up to the added power and stress.

Key Features:

  • SFI certified: Built to meet SFI Foundation safety specifications for performance flexplates, which are commonly required for competition use.
  • Steel construction: Made from steel for strength and durability under hard launches and high-torque loads.
  • Ring gear: Has a starter ring gear that engages the starter motor for reliable engine starting.
  • Performance upgrade: Designed to replace a factory flexplate in performance and racing engine and transmission combinations.
  • Brand heritage: B&M has decades of experience in automatic transmissions, shifters and drivetrain components for racers and enthusiasts.

This flexplate suits builders who want a dependable, certified part for the engine-to-transmission connection. It is available in several variants, so choose the one that matches your engine and transmission setup.
