About this part

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 Pro Street rotating assembly from Eagle is designed to handle the demands of serious competition. It features a precisely machined 3.900-inch stroke crankshaft, built to withstand the stresses of high RPM and significant cylinder pressures. The 6.125-inch I-beam connecting rods are well-built for durability and reliable power transfer from the pistons to the crankshaft.

This assembly includes 4.155-inch bore pistons, ready to be paired with your chosen piston rings and wrist pins to complete the combustion chamber. The crankshaft is configured with a 58-tooth reluctor wheel, essential for proper engine management system operation in LS-based applications. Eagle has a solid reputation for producing robust engine components, and this rotating assembly is no exception. It's a critical foundation for an engine that needs to perform consistently under race conditions.

When assembling a performance engine, attention to detail is key. Ensure all components are properly balanced and clearanced according to manufacturer specifications before installation. This rotating assembly is intended for racing use and is not CARB approved, meaning it cannot be shipped to California. Always refer to the latest installation guidelines and safety warnings from Eagle for your specific build.
