About this part

Product Details

This is the Eagle Chevy LS1 rotating assembly, a complete package designed for serious performance builds. It includes a 3.900-inch crankshaft, 6.125-inch H-beam connecting rods, and 3.913-inch pistons, all balanced and ready to go. This assembly is specifically intended for Chevy LS1 engines and is built to handle the demands of racing applications, including those using nitrous oxide or forced induction.

The crankshaft is forged from high-strength steel, providing a solid foundation for high horsepower output. The H-beam connecting rods are also forged, known for their strength and ability to withstand high RPMs and significant cylinder pressures. The pistons are designed for a 6cc volume, which helps achieve a specific compression ratio when paired with the correct cylinder heads and gasket. The assembly features a 58-tooth reluctor wheel, essential for proper engine management system communication on LS1 engines.

When you're building an engine for racing, the rotating assembly is one of the most critical components. This Eagle Competition Rotating Assembly is a well-built option that takes the guesswork out of matching critical parts. It’s a popular choice for those looking to push their LS1 engine beyond stock capabilities. Please note that this assembly is not CARB approved and cannot be shipped to California.
