Eagle Chevy LS1 3.900in Crank 24 Tth Reluctor 6.125in H-Beam 6cc 3.913in Pistons Rotating Assembly

This is the Eagle Chevy LS1 rotating assembly, designed for serious performance builds. It includes a 3.900-inch stroke crankshaft, 6.125-inch H-beam connecting rods, and 3.913-inch pistons, all balanced and ready to go. This assembly is specifically configured for LS1 engines with a 24-tooth reluctor wheel, making it a direct fit for many popular GM LS-based applications. If you're pushing the limits with nitrous or forced induction, this is the kind of well-built foundation you need to handle the extra stress.

Eagle has put together a robust package here. The H-beam connecting rods are known for their strength and ability to withstand high RPMs and significant cylinder pressures, which is crucial when you're adding boost or a shot of nitrous. The crankshaft is forged for durability, and the pistons are designed to work with the 6cc combustion chamber volume, contributing to a specific compression ratio when paired with the right cylinder heads. This assembly comes balanced, saving you a significant step and potential cost during the engine building process. It’s a smart choice for anyone looking to build a powerful LS engine that can handle demanding racing conditions.

When you're assembling a high-performance engine like this, it's important to ensure all supporting components are up to the task. This rotating assembly is a critical piece, but you'll also need to consider matching it with appropriate camshafts, cylinder heads, and a strong block to realize its full potential. Remember that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations.
