Product Details
If you're building a high-performance naturally-aspirated LS7 engine for racing, a strong rotating assembly is the heart of the operation. This Eagle Pro Street rotating assembly is designed to handle the demands of serious competition, providing a solid foundation for your build. It includes a 3.900-inch crankshaft, 6.125-inch I-beam connecting rods, and 4.125-inch pistons, all balanced and ready to go.
Eagle has a reputation for well-built engine components, and this assembly is no exception. The Pro Street line is specifically geared towards racing applications where reliability and strength are paramount. The I-beam connecting rods offer a good balance of strength and weight for their intended use, while the crankshaft is forged to withstand high RPMs and significant cylinder pressures. The included pistons are sized for a 4.125-inch bore, common in many LS7 builds, and the assembly features a 58-tooth reluctor wheel for compatibility with standard LS engine management systems.
When assembling a performance engine, ensuring all rotating components are properly balanced is critical for longevity and smooth operation. Eagle takes this into account with their rotating assemblies. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or manufacturer's specifications for proper installation and break-in procedures to get the most out of this high-performance rotating assembly.
