The standard Ford EcoBoost 2.3L Forged Crankshaft is optimized for maximum performance and excellent engine response. The standard crankshaft is carefully processed and machined including the removal of the balance shaft drive gear and associated hub. Comprehensive machining of journal arms and other strategic areas of the crankshaft provides additional lightness. Once all machining is completed, the component is processed with various surface treatments to reduce stress producing a part with a refined and superior surface. Includes keyed snout for ease of assembly. This crank is perfect for high-power builds in the Focus RS, Mustang EcoBoost, and those wishing to increase the engine displacement of their *Focus ST.
