Eagle Chevrolet 305/350 1pc Rear Seal 3.480in Stroke Forged 4340 Steel Crankshaft

Starting with a forged 4340 steel construction, this Eagle crankshaft is built for serious performance. The non-twist forging process ensures a solid, reliable foundation for your engine, especially when you're pushing the limits. It's designed for Chevrolet 305 and 350 engines and features a 1-piece rear main seal, a common upgrade for improved sealing and durability over older 2-piece designs.

The .125-inch fillet radii are a notable detail, adding significant strength to the crankshaft where it matters most. Because of these enhanced radii, you'll need to use chamfered or narrowed bearings to ensure proper clearance. The surface is nitrided and micropolished, which helps reduce friction and wear, contributing to a longer lifespan for the component. This crankshaft has a 3.480-inch stroke, making it a solid choice for rebuilding or upgrading your engine's internals.

This crankshaft is a substantial upgrade for your 1993-1997 Chevrolet Camaro, or compatible Buick Roadmaster, Chevrolet Corvette, Chevrolet Impala, and Pontiac Firebird models. It's intended for applications where engine strength and reliability are paramount. Ensure you have the correct chamfered bearings and consult your engine build specifications for proper installation.
