Eagle Chevy LS2/LS3 3.900in Crank 24 Tth Reluctor 6.125in H-Beam 4.000in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly includes a 3.900-inch stroke crankshaft, 6.125-inch H-beam connecting rods, and 4.000-inch pistons designed for Chevy LS2 and LS3 engines. This is a complete package built to handle the demands of high-performance applications, including those using nitrous oxide or forced induction systems. It’s a well-built foundation for a serious engine build.

The crankshaft is forged from high-strength steel and features a 3.900-inch stroke, which is a common upgrade for increasing displacement and torque in LS engines. The 24-tooth reluctor wheel is standard for most LS2 and LS3 applications, ensuring compatibility. The included H-beam connecting rods are known for their strength and rigidity, making them a popular choice for racing and boosted engines. They are paired with 4.000-inch pistons, which, when combined with the 3.900-inch stroke crank, will result in a 400 cubic inch (6.55L) displacement for a 4.000-inch bore LS engine. This assembly is balanced and ready for installation, saving you time and ensuring proper rotating assembly balance.

When building a performance engine, especially one intended for racing, the rotating assembly is critical. This Eagle kit provides a robust and balanced set of components designed to withstand higher cylinder pressures and RPMs. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting components, such as a compatible block, cylinder heads, camshaft, and tuning, to complete your engine build.
