About this part

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 demanding use, including racing applications with nitrous or forced induction.

The H-beam connecting rods are known for their strength and are a popular choice for high-performance builds where reliability under stress is key. The crankshaft is forged from strong material to handle the increased loads from racing, while the pistons are sized to match the bore and stroke for optimal compression and performance. This rotating assembly is a significant upgrade for anyone looking to push their LS engine beyond stock capabilities, especially when adding power-adding modifications like turbochargers or superchargers.

It's important to note that this assembly is not CARB approved and cannot be shipped to California. For builds outside of California, this rotating assembly offers a well-built foundation for a powerful LS engine. Ensure you have all necessary supporting components and follow proper installation procedures for optimal results.
