When you think about crankshafts, Eagle Specialty Products comes to mind for a reason. Their dedication to quality isn't just talk—it's a commitment that's earned them a loyal following among gearheads and professionals alike. Over the years, they've expanded their lineup to include crankshafts and connecting rods, continuously pushing the envelope with innovative designs and top-notch materials. You can really feel the difference when you hold one of their products; it's like they’ve taken everything they’ve learned and packed it into each piece. They’re not just sitting on their laurels, either. Eagle is always on the hunt for ways to make their products lighter, stronger, and more efficient to manufacture. If you’re not moving forward in this game, you’re just getting left behind.
Now, let’s talk specifics. The Eagle forged 4140 steel crankshaft is a beast. It features a non-twist forging process that really amps up its strength, and those .125" fillet radiuses? They’re not just there for show; they help ensure that you won’t have to worry about the crank failing under pressure. Plus, it’s been nitrided for a tough surface and micropolished to less than 2 RA, making it ideal for serious competition use. Just keep in mind, you might need to do a bit of minor block clearancing to get it to fit perfectly.

Since the company started, it has continuously produced some of the market's best engine components and is widely used by engine builders worldwide.
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.

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.
