Eagle Ford 4.6 Stroker 1.889in Rod Journal / 3.750in Stroke 4340 Forged Crankshaft

Eagle is a well-known name for building strong performance engine parts, and this 4340 forged crankshaft is a prime example of their work. If you're looking to build a more powerful Ford 4.6L Modular V8, this crankshaft is designed to handle the extra stress. It features a 3.750-inch stroke, which is longer than stock, giving you more displacement and potential for increased power. The rod journals are 1.889 inches, a specific size that works with certain performance connecting rods.

This crankshaft is forged from 4340 steel, a strong material chosen for its ability to withstand high RPMs and significant power output. It has center counterweights, which help keep things stable when you're pushing the engine hard. The fillet radii are 0.125 inches, which adds to its overall strength, but it means you'll need chamfered or narrowed bearings to fit correctly. To further enhance its durability and smooth operation, the surface is nitrided and then micropolished. This crankshaft is intended for builds where reliability under extreme conditions is a top priority.

This crankshaft fits a wide range of Ford vehicles equipped with the 4.6L Modular V8 engine, including models like the Ford Crown Victoria, Ford Expedition, and Ford Mustang. When installing, remember that the 0.125-inch fillet radii require specific bearing types. It's always a good idea to consult your engine build guide or a trusted mechanic to ensure all components are compatible and installed correctly for optimal performance and longevity.
