Eagle Chevy LS1 3.900in Crank 24 Tth Reluctor 6.125in H-Beam -5cc 3.913in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly starts with a 3.900-inch stroke crankshaft, designed for Chevy LS1 engines. The crankshaft features a 24-tooth reluctor wheel, which is standard for many LS1 applications, and is paired with 6.125-inch H-beam connecting rods. These rods are well-built for the stresses of racing, including those from nitrous and forced induction setups. The assembly includes pistons with a -5cc dish, resulting in a specific compression ratio when paired with the rest of the engine's components.

Eagle has put together this rotating assembly as a complete package for builders looking to maximize performance in demanding applications. The H-beam connecting rods are known for their strength and ability to handle high RPMs and significant cylinder pressures. The 3.913-inch bore pistons are designed to work with the crankshaft and rods to form a balanced rotating assembly. This means that the weight of the pistons, rods, and crankshaft are matched to reduce vibration and ensure smooth operation at high engine speeds.

When building a high-performance LS1 engine, especially for racing, a balanced rotating assembly like this one from Eagle is a critical component. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures to ensure optimal performance and longevity.
