About this part

Product Details

This Eagle Pro Street rotating assembly gives you the core components to build a strong LS7 engine. You get a 3.800-inch stroke crankshaft, 6.125-inch I-beam connecting rods, and 4.130-inch pistons, all balanced and ready for assembly. This package is designed for naturally-aspirated racing applications, providing a solid foundation for high-performance builds where reliability and strength are key.

Eagle has a reputation for well-built engine components, and this rotating assembly is no exception. The Pro Street line is geared towards serious performance, offering a balance of strength and weight savings suitable for demanding use. The crankshaft features a 3.800-inch stroke, which, combined with the 4.130-inch pistons, determines the engine's displacement. The 6.125-inch I-beam connecting rods are a popular choice for their robust design, capable of handling significant stress. This assembly is balanced, which is a critical step in ensuring smooth engine operation and longevity, especially at higher RPMs.

When building an engine of this caliber, attention to detail is paramount. This assembly is intended for naturally-aspirated racing use, meaning it's optimized for engines that don't use forced induction like turbochargers or superchargers. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Ensure you have all necessary supporting components, such as bearings, rings, and gaskets, to complete your engine build. Refer to the manufacturer's installation instructions for specific assembly procedures and torque specifications.
