Eagle Chevy LS2/LS3 3.900in Crank 58 Tth Rlctr 6.125in I-Beam Rods 4.000in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly starts with a 3.900-inch stroke crankshaft, designed to work with Chevy LS2 and LS3 engines. It’s paired with 6.125-inch I-beam connecting rods and 4.000-inch pistons, creating a well-built package for those looking to build a naturally-aspirated racing engine. The I-beam rod design is a popular choice for its strength and relatively light weight, making it suitable for high-RPM applications where responsiveness is key.

The Pro Street designation means this assembly is intended for performance use, particularly in racing scenarios where the engine will be naturally aspirated. This means it’s not designed for forced induction like turbochargers or superchargers, but rather for engines that rely on displacement and airflow for power. Eagle has a reputation for producing solid rotating assemblies, and this kit is put together with components that work well together for a balanced setup. When you're rebuilding the heart of your LS engine for racing, a balanced rotating assembly is crucial for reliability and performance.

This assembly includes the crankshaft, connecting rods, and pistons. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures, as rotating assemblies require precise balancing to ensure smooth operation and longevity.
