MIA's Description

These cast crankshafts offer a modern alternative to older OEM cranks, suitable for street engines without power adders. They are manufactured with updated materials and casting processes, addressing potential issues like stress cracks found in older factory units. The product can also feature ESP Armor, a unique surface finishing process by Eagle designed to reduce bearing friction, lower oil heating, and improve corrosion resistance. All rotating assemblies sold by Butler Performance, including this crankshaft, undergo "The Butler Process" for quality inspection and balancing.
