About this part

Product Details

Eagle is well-known for making strong internal engine components, and this Pro Street rotating assembly is a prime example of their work for Chevy LS7 engines. This assembly is specifically put together for naturally-aspirated racing applications, meaning it's designed to handle the demands of engines that don't use forced induction like turbochargers or superchargers. It's a complete package that gives you the core rotating parts needed to rebuild or upgrade your LS7's bottom end.

Inside this assembly, you'll find a 3.900-inch stroke crankshaft, built to handle the stresses of high-RPM operation. Paired with it are 6.125-inch I-beam connecting rods, a popular choice for their balance of strength and weight in performance builds. The assembly also includes 4.125-inch pistons, completing the set for your LS7. The crankshaft features a 24-tooth reluctor wheel, which is standard for many LS-based engine control systems, ensuring compatibility with your factory or aftermarket ECU. This rotating assembly is a well-built foundation for a powerful, naturally-aspirated LS7 engine.

When undertaking an engine build of this caliber, it's crucial to ensure all components are properly balanced and installed according to manufacturer specifications. This assembly is intended for racing use and is not CARB approved, so it cannot be shipped to California. Always consult your engine builder or the manufacturer's detailed installation guide for the best results and to ensure all necessary supporting components are accounted for in your build.
