About this part

Product Details

If you're building a high-performance LS7 engine for serious racing, a strong rotating assembly is the heart of your build. This Eagle Competition Rotating Assembly is designed to handle the extreme demands of competition, including nitrous and forced induction applications. It features a 3.900-inch stroke crankshaft, 6.125-inch H-beam connecting rods, and -15cc dish pistons with a 4.155-inch bore, all balanced and ready for installation.

Eagle has a reputation for well-built engine components, and this assembly is no exception. The H-beam connecting rods are known for their strength and ability to withstand high cylinder pressures and RPMs, making them a popular choice for racing engines. The included pistons are designed for a 58-tooth reluctor wheel setup, common in many LS applications, and feature a -15cc dish to help achieve your desired compression ratio when paired with appropriate cylinder heads. This assembly is balanced, which is a critical step in ensuring smooth engine operation and longevity, especially at high RPMs.

When undertaking a serious engine build like this, it's important to ensure all components are compatible and installed correctly. This rotating assembly is intended for competition use and is not CARB approved, meaning it 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 robust rotating assembly.
