157 Tooth Flywheel

The 157 Tooth Flywheel from FORD is an essential component for serious engine builders and performance enthusiasts looking to optimize their drivetrain. This OEM-specification flywheel serves as the critical interface between your engine's crankshaft and transmission, transferring power while providing the rotational inertia necessary for smooth engagement and reliable operation. Whether you're building a stroker engine, upgrading your clutch system, or replacing a worn factory component, the 157-tooth count makes this flywheel the correct choice for compatible Ford applications requiring precision fitment and factory-level performance.

The 157-tooth ring gear design matches the starter motor pinion engagement specifications for your particular Ford engine family, ensuring reliable cold-start performance and longevity under repeated cranking cycles. The flywheel's mass (24.4 lbs) and thermal properties are engineered to manage heat transfer from the friction interface while providing sufficient rotational momentum for smooth idle characteristics and predictable engagement feel. The precision-machined friction surface and balanced design minimize vibration and ensure concentricity with the crankshaft, critical for clutch longevity and driveline smoothness across all RPM ranges.

This flywheel is ideal for engine rebuilds, clutch replacements, or resto-mod projects where OEM specifications and compatibility are paramount. Proper installation requires accurate balancing to match your specific crankshaft and clutch assembly weight; many builders pair this component with a matched pressure plate and disc for optimal drivability. The 157-tooth configuration is specific to certain Ford engine displacements and years, so verify your engine code and application before purchase to ensure correct fitment and starter engagement.
