A727 Flexplate (340 Ci.)

The A727 Flexplate (340 Ci.) from B and M AUTOMOTIVE is a purpose-built transmission flexplate designed for Mopar 340 cubic-inch engines paired with Torqueflite 727 automatic transmissions. This component serves as the critical mechanical bridge between the engine crankshaft and torque converter, absorbing shock loads and transmitting rotational force with precision engineering that separates factory-quality rebuilds from substandard aftermarket alternatives.

Constructed from steel, this flexplate is machined to external balance specifications and features a six-bolt crank interface that matches Mopar's original engineering tolerances. The external balance design ensures compatibility with balanced crankshafts and vibration dampers, preventing harmonic imbalances that can accelerate bearing wear and transmission failure. At 4.02 pounds with compact dimensions (14.4 x 0.95 x 14.5 inches), the A727 is engineered for reliability.

Whether you're restoring a classic Mopar muscle car, rebuilding a powertrain after high-mileage service, or upgrading an existing 340 installation, the A727 flexplate delivers the reliability that professionals and enthusiasts demand. With precisely-drilled bolt holes and ring gear engagement surfaces, it is rated for both street and moderate performance driving, making it an essential component for technicians performing Torqueflite 727 transmission rebuilds.
