Steel SFI Flywheel - SBF 164 Tooth 28oz.

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 and weighing 28 ounces, 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. The 164-tooth ring gear provides reliable engagement with modern starters while the steel construction resists the thermal cycling and wear inherent to track use, making it ideal for applications running boost, nitrous, or sustained high-RPM power.

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. At 31 pounds, this flywheel suits applications where weight savings enhance throttle response and reduce underhood inertia, particularly valuable in mid-weight platforms or high-horsepower combinations pushing toward 400+ hp.
