Eagle Chevy LS2/LS3 3.900in Crank 24 Tth Rlctor 6.125in H-Beam 6cc 4.030in Pistons Rotating Assembly

This Eagle rotating assembly starts with a 3.900-inch stroke crankshaft, precision-balanced and ready to handle the demands of high-performance LS2 and LS3 engines. It's designed to work with 4.030-inch bore pistons, giving you a solid foundation for building serious power, whether you're aiming for naturally aspirated performance or incorporating forced induction like turbochargers or superchargers. The 24-tooth reluctor wheel is standard for these LS applications, ensuring compatibility with your engine's computer system.

The heart of this assembly includes 6.125-inch long H-beam connecting rods. These rods are well-known for their strength and ability to withstand the high cylinder pressures and RPMs common in racing. They are paired with pistons designed for a 6cc combustion chamber volume, which helps achieve a specific compression ratio when combined with your cylinder heads and block. This entire package is balanced as a unit, saving you significant machine shop time and ensuring smooth operation right out of the box.

This is a competition-grade rotating assembly, meaning it's built for durability under extreme conditions. While it's not CARB approved and cannot be shipped to California due to emissions regulations, it's an excellent choice for builders focused on maximum performance in racing environments. Ensure you have the correct supporting components, such as pistons, rings, bearings, and gaskets, to complete your engine build.
