This is the Eagle Chevy LS1 rotating assembly, built for 5.7L and 6.0L LS-based engines. It's a complete package designed to form the heart of your engine rebuild, featuring a 4.000-inch stroke crankshaft, 6.125-inch I-beam connecting rods, and 3.905-inch pistons. This assembly is a solid choice when you're looking to build a robust LS engine, whether for a street performance car or a dedicated track machine.

Eagle has put together a well-built rotating assembly here. The crankshaft is forged from 4340 steel, known for its strength and durability under high stress. The 6.125-inch I-beam connecting rods are also forged from 4340 steel, offering a strong yet relatively lightweight option for handling the forces generated by your engine. The assembly includes pistons designed for a 3.905-inch bore, ready to be fitted with your chosen rings and pins. This rotating assembly comes with a 58-tooth reluctor wheel, which is standard for most LS1, LS2, and LS6 applications, ensuring compatibility with your factory or aftermarket ECU.

When undertaking an engine build of this caliber, attention to detail is key. This rotating assembly is balanced, which is a crucial step in reducing engine vibration and improving overall smoothness and longevity. While this assembly is designed for performance, it's important to note that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications to ensure the best possible outcome for your engine build.
