Eagle Chevy 4.8/5.3 LS 3.900in Crank 24 Tth Rlctor 6.125in H-Beam 3.820in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly starts with a 3.900-inch stroke crankshaft, built to handle the demands of high-performance LS engines like the Chevy 4.8L and 5.3L. It's designed for serious racing applications, including those using nitrous oxide or forced induction, meaning it's constructed to withstand significantly higher cylinder pressures and rotational forces than a stock setup. The assembly includes 6.125-inch H-beam connecting rods, known for their strength and ability to manage the stresses of aggressive engine operation. These rods are paired with 3.820-inch pistons, completing the core of a robust rotating assembly ready for a performance build.

Eagle has engineered this assembly with racing in mind, so you can expect well-built components throughout. The H-beam rods offer a strong balance of durability and weight, crucial for maintaining consistent engine operation at high RPMs. The crankshaft's stroke is optimized for the LS platform, aiming to increase displacement and torque potential when paired with the correct bore size. This rotating assembly is a foundational piece for anyone looking to build a powerful and reliable engine for competitive use, whether on the drag strip or the road course.

When considering this rotating assembly, remember it's intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have the necessary supporting components for a complete engine build, such as bearings, rings, and gaskets, as these are typically sold separately. This assembly is a significant step towards a high-horsepower LS engine build.
