Flexplate CM Steel SFI BBC Gen V/VI 91-97

The PRW Industries Flexplate CM Steel SFI BBC Gen V/VI 91-97 is a heavy-duty chromoly flexplate engineered for big-block Chevy engines in Gen V and Gen VI configurations. This 168-tooth unit meets SFI 29.1 certification standards and is designed to handle the demanding torque loads of performance and street applications while maintaining external balance compatibility.

Built from chromoly steel, this flexplate delivers superior strength compared to standard iron alternatives, crucial for high-horsepower big-block engines where reliability is non-negotiable. The 168-tooth ring gear provides precise engagement with modern starter systems. The one-piece seal design simplifies installation and eliminates potential leak paths at the seal interface. As an external-balance component, it matches the specific harmonic characteristics of your engine's crankshaft and damper combination—a critical factor that many builders overlook but that directly impacts vibration control and component longevity.

This flexplate is purpose-built for street performance, drag racing, and high-output big-block applications where factory parts fall short. Whether you're rebuilding a 454, 502, or other BBC displacement, the SFI certification confirms compliance with safety standards required for organized racing and street performance use. Installation requires verification of existing balance specifications to ensure compatibility with your crankshaft and damper assembly.

The 7.34 lb weight reflects the solid construction typical of quality chromoly flexplates. PRW Industries is recognized in the performance engine community for precision manufacturing and attention to OEM compatibility details. Each unit ships as a single component ready for immediate installation on Gen V/VI BBC platforms manufactured from 1991 through 1997.
