Chromoly Flexplate - SFI SBC/BBC 168 Tooth

The PRW Industries Chromoly Flexplate for SBC/BBC 168 Tooth is a high-performance internal balance flexplate engineered for small-block and big-block Chevrolet engines requiring SFI 29.1 certification. This chromoly flexplate combines proven durability with precision engineering, delivering the strength needed for serious street, strip, and engine rebuild applications where reliable power transfer between engine and torque converter is critical.

Built from chromoly steel, this 168-tooth flexplate is designed for internal-balance engines and features a two-piece seal configuration that minimizes oil leakage around the crankshaft. The SFI 29.1 safety certification ensures compliance with racing and performance engine standards, making it suitable for modified vehicles where factory components no longer meet dynamic load requirements. The 14.1-inch diameter matches OEM Chevy specifications while the internal balance design eliminates the need for external weight distribution, streamlining installation and reducing rotating mass complexity.

This flexplate serves engine builders, restoration shops, and performance enthusiasts replacing worn or damaged OEM components, or upgrading to stronger hardware for increased displacement, boost, or compression. The 168-tooth count ensures compatibility with matching torque converters and transmission bell housings in Chevrolet power plants. Whether building a carbureted street engine, LS conversion platform, or race-prepped BBC, this PRW flexplate provides the structural integrity and certification required for reliable operation under sustained power delivery.
