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 designed for Chevy LS1 engines and includes a 3.900-inch crankshaft, 6.125-inch H-beam connecting rods, and pistons with a -15cc dish volume, resulting in a 3.903-inch bore size. It also features a 24-tooth reluctor wheel, making it suitable for a wide range of LS1 applications.
This is a competition-level assembly, meaning it's built to handle the stresses of racing, including the demands of nitrous oxide and forced induction setups. The H-beam connecting rods are known for their strength and rigidity, which is crucial for maintaining proper piston and crank alignment under high loads. The pistons are designed to work with the included crankshaft and rods to achieve a specific compression ratio, indicated by the -15cc dish volume. This assembly is a solid foundation for a high-performance LS1 build where reliability and power are paramount.
When building a performance engine, the rotating assembly is one of the most critical pieces. It's important to ensure all components are balanced and compatible. This Eagle assembly is designed to be a complete package for your LS1, simplifying the process of sourcing individual parts. Please note that this assembly is not CARB approved and cannot be shipped to California.
