About this part

Product Details

Built from strong 4140 forged steel, the crankshaft in this Eagle rotating assembly features a 4.250-inch stroke, ready to handle serious power for your Chevy 454 engine. This assembly is designed for builders looking to maximize displacement and performance, typically for performance street or racing applications where increased cubic inches are desired. The robust construction of both the crank and the included 6.385-inch long I-beam connecting rods means this assembly is well-suited for engines that will see demanding use.

Complementing the crankshaft and rods are the 4.280-inch bore pistons, designed to achieve a 15cc dish volume. This dish volume, combined with your cylinder head choice, will determine your final compression ratio. The I-beam connecting rods are a popular choice for their balance of strength and weight, making them suitable for a wide range of performance builds. Eagle has a solid reputation for producing well-built internal engine components, and this rotating assembly reflects that commitment to durability and performance.

When assembling this rotating kit, proper balancing is crucial for engine longevity and smooth operation, especially with a stroker crank. You'll want to ensure all components are balanced as a complete rotating assembly by a professional machine shop. This kit is not CARB approved and cannot be shipped to California. Please consult your local emissions regulations before purchasing.
