Eagle Chevy LS1 3.900in Crank 24 Tth Reluctor 6.125in H-Beam -5cc 3.903in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this rotating assembly is a prime example of their commitment to performance. This particular assembly is designed for Chevy LS1 engines and is engineered for demanding competition use, including applications with nitrous oxide or forced induction like turbochargers and superchargers. It’s a complete package that brings together a crankshaft, connecting rods, and pistons, ready to be the heart of a high-performance build.

At the core of this assembly is a 3.900-inch stroke crankshaft, paired with 6.125-inch H-beam connecting rods. H-beam rods are a popular choice for performance builds because their I-beam shape is reinforced, making them stronger and more rigid than standard I-beam rods, which is crucial when dealing with the increased cylinder pressures from boost or nitrous. The assembly also includes pistons with a -5cc dish volume, designed to work with the specific bore size and stroke to achieve a desired compression ratio for your LS1 engine. The 24-tooth reluctor wheel is standard for most LS1 applications, ensuring compatibility with your engine's computer system.

This is a comprehensive rotating assembly, meaning it includes the key rotating components needed to rebuild or significantly upgrade your LS1 engine's bottom end. While it's built for serious performance, remember that this assembly is not CARB approved and cannot be shipped to California. For optimal results and longevity, always refer to the manufacturer's detailed installation instructions and recommended clearances for your specific application.
