If you're diving into the world of high-performance engines, you’ve probably heard of Eagle Crankshafts. These bad boys are all about strength and reliability without breaking the bank. I’ve had my hands on a few of these cranks, and let me tell you, they’re built to last. Each crank is forged using a non-twist process, which means they’re not just thrown together—they’re crafted with precision. Plus, they go through a rigorous multi-stage heat treatment, stress relieving, shot peening, and nitriding. It’s like they’re put through boot camp before they even hit your engine.
One of the standout features is the micropolished journals. They’re polished to a smoothness of 3 R.A. or better, which is crucial for reducing friction and improving longevity. And those .125” radius edges? They’re not just for show; they boost strength significantly, but keep in mind, you’ll need to use chamfered bearings to match. These cranks are designed for serious power—up to 1500 horsepower, to be exact. That’s the kind of muscle you want when you’re building something that roars.
Now, if you’re looking for something a bit lighter, Eagle also offers 'Lightweight' versions. They’ve got knife-edged counterweights that shave off about 5-6 lbs. You’d be surprised how much that can help with windage and overall performance. It’s all about that balance, right?
For those of you who might be considering a cast option, Eagle’s cast steel crankshafts are a solid alternative to factory cranks. They’re designed with .092” radii, so you can stick with O.E. style bearings. They’re good for up to 500 horsepower and are engineered for a 28 in-oz. external balance. You can trust these cranks to perform without the worry of factory flaws.

Note: Make sure to balance the crankshaft to match your specific rods and pistons for optimal performance.
So if you’re looking to upgrade your ride with a crank that can handle serious power and keep running strong, the Eagle Forged 4340 Crankshaft is definitely worth considering.

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.
