If you're looking to beef up your Briggs & Stratton engine, this Eagle Specialty Products 4340 Billet Crankshaft is a solid choice. Made from tough 4340 steel, it’s built to last. The .125" fillet radiuses give it that extra strength you want, which means fewer worries about wear and tear down the line. Just keep in mind that you'll need chamfered or narrowed bearings to make it fit right.
Universal Fitment: While this crankshaft is designed to be versatile, it's always a good idea to double-check compatibility with your specific setup. Do your homework to ensure it’s a good match for your engine.
Prop 65 Warning: This product contains nickel, which the State of California has linked to cancer. Just something to keep in mind while you're working on your build.

Imitated But Not DuplicatedDue to the company's success, its products have been imitated by other companies even up to the part numbers. But the similarity ends only up to how they look. EAGLE uses the finest materials and has invested in the most state-of-the-art manufacturing machinery for them to create a product that would be able to take any punishment it is subjected to. It is tested to be superior to other brands and considered the best upgrade for OEM counterparts.
No To ShortcutsThe company sets the benchmark on how valves should be properly made. Using their years of experience creating rods, they have already designed over 200 different rods and 180 crankshafts. The company does not allow cost to compromise its material used, manufacturing process, and quality test.
High-End QualityAll of Eagle's products are made up of high-quality materials. They use certified 4340 Chromoly steel. Using their own special heat treatment process, they are able to create a product that is much stronger compared to other competitors using the same raw material.
They manufacture their rods using a 2-piece forging process that allows the rod to be stronger. This process orients the "grain" of the metal to the direction of the stress. Eagle uses a state-of-the-art Sunnen Krossgrinding system that allows them to create perfect cuts and bore consistently.
