About this part

Product Details

When you're building a high-performance Chevy LS2 or LS3 engine for serious racing, especially with nitrous or forced induction, the rotating assembly is the heart of the operation. This Eagle Competition Rotating Assembly is built to handle the extreme demands of competition, giving you a solid foundation for significant power gains. It's designed to increase displacement and handle the stresses of high-RPM operation.

This assembly includes a 3.900-inch stroke crankshaft, which, when paired with the 4.060-inch bore pistons, creates a larger displacement engine. The 6.125-inch H-beam connecting rods are well-known for their strength and ability to withstand high cylinder pressures and shock loads common in racing applications. The pistons are designed for a 6cc volume, which is important for achieving the correct compression ratio with your chosen cylinder heads. Eagle is a well-known name in performance engine components, and this assembly reflects their focus on durability and performance for demanding builds.

This rotating assembly is a critical component for anyone pushing the limits of their LS engine. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure you have the correct supporting components, such as pistons, rings, bearings, and balancing, to complete the installation and achieve optimal performance from this competition-grade assembly.
