Eagle Chevrolet Big Block Stock Stroke For 454 / 502 Forged Crankshaft

This is an Eagle forged 4340 steel crankshaft, specifically made for Chevrolet big block engines like the 454 and 502. It's designed for internal balance and offers a stock stroke, making it a solid choice for rebuilding or upgrading your engine's core rotating assembly. When you're building an engine that needs to handle serious power, the crankshaft is one of the most critical components, and this forged steel unit is built to take a beating.

Eagle uses a non-twist forging process for this crankshaft, which means it's incredibly strong and resistant to flexing under load. They've also added .125" fillet radii, which are chamfered or narrowed to accept specific bearings, further increasing its strength. The surface treatment includes nitriding and micropolishing, processes that harden the steel and create an exceptionally smooth finish. This combination of advanced materials and manufacturing techniques results in a crankshaft that's well-built for demanding applications where reliability and durability are paramount.

Because this crankshaft features .125" fillet radii, you'll need to use chamfered or narrowed bearings to ensure proper fitment and function. This is a common practice on high-performance cranks to maximize strength in critical areas. If you're working on a high-horsepower build or a heavy-duty application, this Eagle crankshaft is a well-made foundation for your engine.
