Chromoly Flexplate - SFI SBC 168T - Int. Balance

The PRW Industries Chromoly Flexplate - SFI SBC 168T - Internal Balance is a heavy-duty crankshaft coupling engineered for Small Block Chevy and V6 engines requiring SFI 29.1 certification. This 168-tooth flexplate combines chromoly construction with internal balancing to deliver reliable engine-to-transmission engagement in high-performance and street applications where factory components may fall short of durability demands.

The Gold Series design features a two-piece seal configuration that accommodates modern transmission housings while maintaining precise concentricity with the crankshaft. Internal balancing ensures smooth power delivery without the weight penalties of externally balanced assemblies, a critical advantage in engines tuned for responsive throttle response. The 168-tooth count matches factory Small Block Chevy firing intervals, making this flexplate compatible with OEM and aftermarket starter motors across the widest range of engine configurations. Chromoly material provides superior fatigue resistance compared to cast iron, particularly important in high-revving builds or engines subject to sustained load cycling.

This component serves builders and street enthusiasts upgrading Small Block Chevy or V6 drivetrains where OEM flexplates lack adequate strength or balancing precision. SFI 29.1 certification confirms the flexplate meets safety standards for competition and high-performance engine builds. Weighing 7.12 lbs, the flexplate integrates seamlessly into engine bays without requiring custom modifications to transmission bell housings or crankshaft provisions. Buyers selecting this flexplate typically pair it with performance torque converters, heavy-duty transmissions, or upgraded clutch systems in vehicles experiencing increased horsepower or frequent high-load operation.
