Product Details

This Eagle Competition Rotating Assembly is a complete package for your Chevy 4.8L or 5.3L LS engine build. You get a 3.900-inch crankshaft, 6.125-inch H-beam connecting rods, and 3.780-inch pistons, all designed to work together as a balanced unit. This assembly is built for serious performance, making it a solid choice for racing applications, including those using nitrous or forced induction.

Eagle has put together this rotating assembly with durability and performance in mind. The H-beam connecting rods are known for their strength, which is crucial when you're pushing an engine hard, especially with added boost or nitrous. The crankshaft is forged for strength, and the pistons are designed to handle the demands of competition. Having a balanced rotating assembly like this is key to a smooth-running and reliable high-performance engine, reducing vibrations and ensuring consistent power delivery.

When building a performance LS engine, especially one intended for racing, a well-matched rotating assembly is fundamental. This Eagle kit simplifies the process by providing the core components that need to be precisely balanced and compatible. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder or refer to manufacturer instructions for proper installation and balancing procedures.
