SBC 168 Tooth Flexplate - SFI - Int. Balance

The ATI 915541 SBC 168 Tooth Flexplate is a steel internal balance flexplate engineered specifically for small block Chevy engines requiring SFI 29.1 certification. Built for high-performance street and race applications, this 168-tooth flexplate serves as the critical coupling point between the engine's crankshaft and the torque converter in automatic transmission systems, designed to handle sustained power delivery while meeting sanctioning body safety standards.

Internal balance design means the rotating mass is pre-balanced within the flexplate itself, eliminating the need for external balancing weights and simplifying installation on balanced small block Chevy engines. The 168-tooth configuration provides the standard tooth count for most small block Chevy automatic applications. SFI 29.1 certification indicates this flexplate meets the Safety First Independent specification for flexplate strength and integrity, required for competition use and increasingly demanded by serious street performance builders. The two-piece seal design facilitates proper oil sealing at the transmission interface. At 7.65 lbs, the flexplate delivers structural rigidity without excessive mass.

This flexplate is the choice for small block Chevy engine builders upgrading from cast iron originals to a performance-grade alternative. Engine builders, transmission specialists, and performance shops specify ATI flexplates for high-horsepower builds where factory components may not provide adequate margin of safety. Whether supporting a fresh 350 stroker in a street cruiser or a nitrous-assisted bracket racing engine, an SFI-certified flexplate is essential insurance against catastrophic failure under load.
