Description

Finding an OEM flywheel for a Mustang II V8 is notoriously difficult - the originals are scarce and command a premium when they surface. This lightened billet steel flywheel solves that problem while delivering a significant performance upgrade over the heavy factory unit. By reducing rotating mass to just 21 pounds, this flywheel improves throttle response and allows the engine to rev more freely, making the most of the 302's available horsepower.

The Mustang II V8 uses a unique 148-tooth ring gear - different from the 157-tooth flywheel found in other Ford applications. This flywheel is machined specifically for Mustang II fitment, ensuring proper starter engagement without modification. The 28oz external balance matches the factory Windsor crankshaft balance, eliminating vibration concerns and maintaining smooth operation throughout the RPM range.

Billet steel construction provides the strength and heat capacity that aluminum alternatives lack. Where aluminum flywheels can warp or crack under repeated heat cycles, billet steel maintains its integrity through aggressive street driving and high-performance use. The 10-inch long pattern clutch mounting surface accepts both OEM and performance clutch assemblies, giving you flexibility in your clutch selection.

Designed specifically for 1974-1978 Mustang II V8 applications with 302 or 351 Windsor engines. This flywheel is manufactured in the USA with precision CNC machining and rigorous quality standards.
