BBF 164 Tooth Flexplate

The BBF 164 Tooth Flexplate from J-W Performance is a crucial component for the engine-to-transmission interface, specifically designed for high-performance big-block Ford applications. This flexplate is ideal for both automotive enthusiasts and professional engine builders who require reliability under extreme horsepower and torque conditions. It serves as a vital link between the crankshaft and torque converter, ensuring smooth power transfer and converter engagement.

Engineered with precision, the 164-tooth design provides consistent starter engagement across the entire ring-gear surface, which is particularly important for high-compression builds that need dependable cold and hot starts. The flexplate is constructed to endure the torsional forces generated by large-displacement motors while maintaining the necessary flex characteristics to protect both the crankshaft and transmission from shock loads during acceleration and gear shifts. Its balanced design minimizes vibration harmonics, reducing fatigue on connecting components in the drivetrain.

This flexplate is suitable for builders working with both carbureted and fuel-injected big-block Ford engines, making it a versatile choice for various performance applications. Whether upgrading a stroker motor or rebuilding a classic big-block installation, this component is essential for achieving optimal performance. With its robust tooth geometry, it ensures smooth starter motor engagement, preventing common issues like grinding or chatter that can occur with lesser aftermarket units.
