About this part

Product Details

The .125" fillet radii on this Eagle cast crankshaft are a notable design choice that significantly increases its strength over a stock unit. This means you'll need to use chamfered or narrowed bearings when installing it, a small detail that makes a big difference in durability. It's built to be IMCA legal, with no lightening holes on the second or third throw, making it a solid alternative and an upgrade from an OE crankshaft for your Chevrolet 350 engine.

This crankshaft is a well-built cast iron piece, offering a strong foundation for your engine build. Its 3.480-inch stroke is a common size that works well for a variety of performance applications. The 1-piece rear main seal design simplifies installation and helps prevent leaks compared to older 2-piece seal setups.
