About this part

Product Details

Eagle is well-known for building strong internal engine components, and this rotating assembly is a prime example of their commitment to performance. This specific assembly is built for Chevy LS1 engines and is designed for serious racing applications, including those using nitrous or forced induction. It's a complete package that brings together a crankshaft, connecting rods, and pistons, all balanced and ready to be installed into your engine block.

At the heart of this assembly is a 3.800-inch stroke crankshaft, paired with 6.125-inch H-beam connecting rods. These H-beam rods are a popular choice for high-stress builds because their design offers a strong balance of strength and weight. The assembly also includes 3.903-inch diameter pistons, designed with a 6cc dish to help achieve a specific compression ratio when combined with your cylinder heads. The crankshaft features a 58-tooth reluctor wheel, which is standard for most LS1 applications, ensuring compatibility with your engine's computer system.

This is a competition-level rotating assembly, meaning it's built with materials and tolerances to handle the demands of racing. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. For a successful installation, always refer to the manufacturer's detailed instructions and ensure all related components are compatible with your specific engine build.
