Chromoly Flexplate - SFI SBC/BBC 168 Tooth

The PRW Industries Chromoly Flexplate for SBC/BBC 168 Tooth is purpose-built for serious small-block and big-block Chevy engine builders who demand reliability under high RPM and high-torque conditions. This flexplate replaces the factory stamped-steel design with a robust chromoly construction, making it an essential upgrade for performance applications including drag racing, street performance builds, and forced-induction engines. Whether you're running a stock converter or upgrading to a modern torque converter setup, a quality flexplate is critical infrastructure that transfers engine power to the transmission without deflection or failure.

Chromoly steel offers superior strength-to-weight ratio compared to factory stamped flexplates, resisting harmonic vibration and flexing that can cause converter misalignment, seal leaks, and catastrophic transmission damage. The 168-tooth design is the industry standard for small-block and big-block Chevy applications, ensuring precise engagement with your torque converter's stator splines. PRW's engineering maintains tight tolerances on the mounting surface and ring gear interface, critical factors for converter durability and smooth power delivery across the entire RPM band. The lightweight construction—at just 7.02 lbs—helps reduce rotating mass without sacrificing structural integrity, a key consideration in high-performance drivetrains where parasitic loss matters.

This flexplate is ideal for anyone building or rebuilding an SBC or BBC engine for performance use, from weekend bracket racers to street enthusiasts pushing serious horsepower. Installation is straightforward—bolt it to your cleaned and inspected crankshaft flange using factory fastener specs—but proper torque sequence and balancing consideration are non-negotiable. The 168-tooth configuration is compatible with virtually all Chevy-specific torque converters and automatic transmissions, including vintage and modern units, making it a universal solution for restoration and performance builds alike. Consider this a mandatory upgrade whenever you're rebuilding a transmission or pushing beyond stock power levels.
