Steel SFI Flywheel - Pontiac V8 166 Tooth

The PRW Industries Steel SFI Flywheel for Pontiac V8 with a 166-tooth design is engineered for serious engine builders and performance enthusiasts who demand reliability in high-rpm and forced-induction applications. Built to SFI certification standards, this steel flywheel serves as the critical interface between your engine's crankshaft and transmission, handling the rotational demands of modified powerplants where stock components may not suffice.

This 166-tooth steel flywheel is designed to resist warping under sustained heat cycles common in aggressive street and strip driving. Weighing 31.15 pounds, it strikes a balance between adequate rotating mass for smooth engagement and manageable inertia—heavier than aluminum race flywheels but lighter than many stock components, which improves throttle response without sacrificing drivability. SFI certification ensures the flywheel meets stringent safety standards for engine containment, especially critical for turbocharged and supercharged applications.

The precision 166-tooth count is factory-matched to Pontiac V8 starter systems, guaranteeing reliable cold starts and seamless engagement every time. This flywheel is ideal for high-performance applications, providing the durability and performance enhancements that serious enthusiasts demand.
