About this part

Product Details

This Eagle Competition Rotating Assembly is a complete package for your Chevy LS7 engine build. You get a 3.900-inch stroke crankshaft, 4.125-inch bore pistons with a -5cc dish, and 6.125-inch H-beam connecting rods. This assembly is designed to handle the demands of high-performance racing, including applications using nitrous oxide or forced induction.

The crankshaft is forged from high-strength steel for durability under extreme stress. The H-beam connecting rods are also forged, offering a strong and reliable link between the pistons and the crankshaft. The pistons are designed for a -5cc combustion chamber volume, which is a common specification for LS7 builds aiming for specific compression ratios. This assembly includes a 24-tooth reluctor wheel, which is crucial for proper engine management system communication on many LS-based engines.

When building a serious performance engine, the rotating assembly is the heart of the operation. Eagle has a reputation for well-built components that can withstand the rigors of competition. This kit is a solid option if you're looking for a matched set of critical internal engine parts that are ready for a high-horsepower application. Please note that this assembly is not CARB approved and cannot be shipped to California.
