Eagle 4G63 Stock Stroke 88mm Crankshaft - 7 Bolt Flange

Starting with a non-twist forging of 4340 steel, this Eagle crankshaft is built for serious performance. It's designed for the Mitsubishi 4G63 engine with a 7-bolt rear flange and a stock 88mm stroke. This is a solid choice if you're rebuilding or upgrading your engine and need a crankshaft that can handle more than stock power levels.

The fillet radii on this crank are .125 inches, which means you'll need to use chamfered or narrowed bearings for proper fitment. Eagle also treats the surface with a nitride finish and micropolishes it. This process helps improve wear resistance and ensures a smooth finish for the bearings, which is critical for long-term engine health. The 4340 steel itself is well-known for its strength and durability, making this a strong foundation for a performance engine build.

This crankshaft is a direct fit for the 7-bolt Mitsubishi 4G63 engine found in a range of vehicles including the 1993-1999 Mitsubishi Eclipse, 1993-1998 Eagle Talon, 1993-1994 Plymouth Laser, and the 2003-2006 Mitsubishi Lancer. When installing, be sure to follow the manufacturer's recommendations for bearing selection and assembly procedures to get the most out of this well-built component.
