About this part

Product Details

Starting with a 3.800-inch stroke crankshaft, this Eagle Competition Rotating Assembly is built for serious performance, especially in racing environments that might include nitrous or forced induction. The crankshaft itself is designed for the Chevy LS7 platform and features a 58-tooth reluctor wheel, which is crucial for proper engine management and timing on these specific engines. This assembly is a complete package, meaning you get all the core components needed to rebuild or significantly upgrade your engine's bottom end.

The H-beam connecting rods measure 6.125 inches in length, a common and strong choice for LS engines that balances stroke with rod ratio for good power delivery and durability. Paired with these rods are 4.155-inch pistons, which, when combined with the crankshaft's stroke, determine the final displacement of your engine. These pistons are designed with a 6cc volume, which will affect your final compression ratio depending on your cylinder head chamber size. Eagle is known for producing well-built rotating assemblies that can handle the stresses of competition, making this a solid option for builders aiming for maximum output and reliability.

This assembly is intended for competition use and is not CARB approved, so it cannot be shipped to California. It's important to note that while this is a comprehensive rotating assembly, you will still need to source other essential engine components like bearings, piston rings (if not included with pistons), gaskets, and potentially cylinder heads and camshafts to complete your engine build. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
