Pontiac 166 Tooth SFI Flywheel

The Pontiac 166 Tooth SFI Flywheel is a precision-engineered component designed for high-performance and rebuilt engine applications where OEM or racing-grade rotational mass control is essential. Built to SFI (Society of Automotive Engineers International) certification standards, this flywheel is suitable for Pontiac enthusiasts, engine builders, and restoration shops.

This flywheel features a 166-tooth design that serves as the critical interface between your starter motor and engine crank. TCI's engineering maintains precise tooth geometry and spacing to help prevent grinding or slip-out during cold starts and high-RPM operation. The SFI certification indicates that this flywheel meets stringent testing for structural integrity, balance, and burst resistance.

Ideal for engine rebuilders and those preparing vehicles for track duty, this component is designed to minimize unsprung rotational mass while maintaining the inertial characteristics required for smooth power delivery. Whether upgrading from a worn factory unit or assembling a stroker motor, this flywheel is a reliable choice for performance applications.
