Pro Series Flexplate SFI 29.1 SBF 157T

The Pro Series Flexplate SFI 29.1 SBF 157T is a purpose-built flexplate engineered for Small Block Ford engine swaps and high-performance rebuild applications where reliability and safety certifications matter. This component sits between your engine's crankshaft and torque converter, transmitting rotational force while absorbing shock loads from both the engine and transmission. Whether you're restoring a classic muscle car, upgrading a street rod, or completing a modern SBF conversion, a quality SFI-certified flexplate is non-negotiable for both durability and legal compliance on the street or track.

Built from steel with internal balancing, this Pro Series flexplate features a 157-tooth ring gear configuration optimized for Small Block Ford engines and carries SFI 29.1 certification, the industry standard for rotating assembly safety in both street and competition environments. The internal balance design eliminates the need for external weight correction, simplifying installation and ensuring precise engine balance without compromises. Its two-piece seal arrangement provides superior leakage prevention at the crankshaft interface, reducing oil seepage and extending component life under sustained load.

This flexplate is ideal for builders and enthusiasts upgrading late-model automatic transmissions onto classic or stroker Small Block Ford applications, or anyone replacing a worn stock flexplate with a performance-grade alternative. At 6.55 lbs, it delivers reliable weight distribution and compatibility with standard SBF bell housings and 157-tooth torque converter stators. Proper installation requires torque specifications per engine manufacturer guidelines and careful alignment to prevent vibration issues; verify your specific SBF block year and transmission bellhousing before ordering to ensure correct fitment.
