Product Details
This Eagle Pro Street Rotating Assembly includes a 3.800-inch crankshaft, 6.125-inch I-beam connecting rods, and 4.005-inch pistons, all specifically balanced for Chevy LS2 and LS3 engines. This is a complete package designed to be the heart of your performance engine build, especially if you're aiming for naturally-aspirated racing applications.
Eagle has put together a well-built rotating assembly here, focusing on strength and reliability for demanding use. The I-beam connecting rods are a solid choice for handling the stresses of high-RPM operation, and the crankshaft is forged to withstand significant power. The included pistons are sized for a 4.005-inch bore, a common size for LS engine builds looking to increase displacement. This assembly comes balanced, which is a critical step that saves you time and ensures smoother engine operation and longevity. Proper balancing is key to reducing vibration and preventing premature wear on bearings and other internal components.
When building a performance engine, especially for racing, a balanced rotating assembly like this one from Eagle is a smart investment. It simplifies the assembly process by providing matched components that are ready to be installed. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted mechanic for specific installation procedures and any additional components you might need for your particular build.
