Product Details
If you're building a high-performance Chevy LS2 or LS3 engine, especially one intended for racing, nitrous, or forced induction, a robust rotating assembly is crucial. This Eagle Competition Rotating Assembly is designed to handle the extra stress these applications put on internal engine components. It includes a 3.900-inch crankshaft, 6.125-inch H-beam connecting rods, and 4.000-inch pistons, all balanced and ready for installation.
The heart of this assembly is the forged crankshaft, built to withstand the demands of high horsepower. Paired with the strong H-beam connecting rods, which are a popular choice for their strength-to-weight ratio in performance builds, this setup offers a solid foundation for your engine. The included pistons are sized for a 4.000-inch bore and are designed to work with a 6cc combustion chamber volume, which is common for LS engines. This assembly is balanced, meaning the critical components have been weighted and matched to reduce engine vibration and improve overall smoothness and longevity.
When undertaking a performance engine build of this caliber, it's important to ensure all components are compatible and installed correctly. This assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and torque specifications to ensure proper assembly and performance of your engine.
