About this part

Product Details

This is the Eagle Chevy 4.8/5.3 LS rotating assembly, featuring a 3.800-inch crankshaft, 6.125-inch H-beam connecting rods, and 3.820-inch pistons. It's designed specifically for the 4.8L and 5.3L LS engines, which are common in many Chevrolet vehicles. A rotating assembly is the heart of your engine's short block, converting the linear motion of the pistons into the rotational force that eventually powers your wheels. This assembly is a well-built package that brings together the key components needed for a robust engine build.

Eagle has put together this competition-grade assembly with components suitable for demanding applications. The 6.125-inch H-beam connecting rods are known for their strength and ability to handle higher RPMs and increased cylinder pressures, making them a popular choice for performance builds. The crankshaft is forged and balanced, ready to withstand the stresses of racing, including the added demands of nitrous oxide or forced induction like turbochargers or superchargers. The 58-tooth reluctor wheel is standard for many LS applications, ensuring compatibility with your engine's computer system. This assembly is a solid option if you're looking to build a powerful LS engine for racing or high-performance street use.

When undertaking an engine build of this caliber, it's important to ensure all components are properly balanced and installed according to manufacturer specifications. This rotating assembly is a critical part of that process, providing a strong foundation for your engine's power output. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper assembly and balancing procedures.
