About this part

Product Details

This Eagle Chevy LS2/LS3 rotating assembly is a complete package designed for serious performance builds. It includes a 3.900-inch crankshaft, 6.125-inch H-beam connecting rods, and 4.065-inch pistons, all balanced and ready to go. This assembly is specifically intended for LS2 and LS3 engines, providing a solid foundation for builds aiming for significant power gains, especially those using nitrous or forced induction.

Eagle has put together this competition-grade assembly with durability and performance in mind. The H-beam connecting rods are well-known for their strength, making them a popular choice for engines that will see hard use on the track or in demanding street applications. The crankshaft is forged for strength, and the included pistons are sized to match the bore and stroke, ensuring a complete rotating assembly that’s ready for installation. This isn't just a collection of parts; it's a balanced system engineered to handle the stresses of high-horsepower engines.

When building a high-performance LS engine, the rotating assembly is one of the most critical components. This Eagle assembly takes the guesswork out of selecting compatible, strong parts. It’s important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to the manufacturer's installation instructions for proper balancing, assembly, and break-in procedures to ensure the longevity and performance of your engine.
