Product Details
If you're building a high-performance Chevy LS2 or LS3 engine for serious racing, this Eagle competition rotating assembly is a solid foundation. It's designed to handle the demands of competition, including applications using nitrous oxide or forced induction like turbochargers and superchargers. This assembly includes a 3.800-inch stroke crankshaft, 6.125-inch H-beam connecting rods, and 4.040-inch pistons, all balanced and ready for installation.
Eagle has put together a well-built package here, focusing on strength and reliability for demanding use. The H-beam connecting rods are known for their robust design, capable of withstanding higher cylinder pressures and RPMs often found in racing engines. The crankshaft is forged for durability, and the included pistons are sized for a 4.040-inch bore, commonly used in LS engine builds. This assembly is balanced, which is a critical step in ensuring your engine runs smoothly and minimizes vibration, especially at high RPMs. It's a comprehensive kit that saves you the time and effort of sourcing each component individually and ensuring their compatibility.
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. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and torque specifications for proper assembly and to ensure the longevity of your build.
