This Eagle Competition Rotating Assembly is a well-built package for your Chevy 4.8L or 5.3L LS engine, designed specifically for high-performance applications. If you're building an engine for racing, especially one that will use nitrous or forced induction, this assembly is a solid choice to form the heart of your build. It includes a 3.900-inch crankshaft, 6.125-inch H-beam connecting rods, and 3.780-inch pistons, all balanced and ready to go.

Eagle has put together a robust rotating assembly here. The H-beam connecting rods are known for their strength and ability to handle significant stress, making them a popular choice for boosted or nitrous applications. The crankshaft is forged for durability, and the included pistons are sized to match the bore and stroke for optimal performance. This assembly is balanced, which is a critical step in ensuring smooth engine operation and longevity, especially at higher RPMs. It's a complete rotating assembly, meaning the crankshaft, connecting rods, and pistons are designed to work together as a unit.

When undertaking a performance engine build of this caliber, it's important to ensure all supporting components are up to the task. This includes the engine block, cylinder heads, camshaft, and fuel system. Because this assembly is intended for competition use, it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures to get the most out of this high-performance rotating assembly.
