The Steel SFI Flywheel - SBF 164 Tooth 28oz from PRW Industries is purpose-built for small-block Ford engine builders seeking reliable, lightweight performance without compromise. SFI-certified flywheels are essential for any serious engine swap, high-RPM application, or drag racing build where safety and durability matter.

This PRW offering delivers the precision inertia characteristics and burst-resistance certification required for competitive motorsports and street performance builds alike. Manufactured from solid steel, this 164-tooth flywheel balances reduced rotating mass with sufficient inertia to maintain smooth engine characteristics across the RPM band. The SFI certification ensures the unit meets rigorous safety standards for high-speed operation, including burst-testing protocols that verify material integrity under extreme centrifugal loads.

Small-block Ford engine builders—whether street, strip, or road race focused—benefit from PRW's reputation for quality ring-gear machining and runout tolerances that ensure smooth clutch engagement. Installation requires standard SBF bolt pattern compatibility; confirm your clutch, pressure plate, and transmission input shaft alignment before ordering. With a weight of 31 lbs, this flywheel is designed to withstand the demands of high-performance applications.
