Eagle Chevy 4.8/5.3 LS 3.800in Crank 58 Tth Rlctor 6.125in H-Beam 3.898in Pistons Rotating Assembly

If you're building a high-performance LS engine for serious racing, a robust rotating assembly is the heart of your build. This Eagle Competition Rotating Assembly is designed to handle the extreme demands of competition, including applications using nitrous oxide or forced induction like turbochargers and superchargers. It's a well-built foundation for your LS project, ensuring reliability when you push your engine to its limits.

This assembly features a 3.800-inch stroke crankshaft, paired with 6.125-inch H-beam connecting rods. H-beam rods are a popular choice for performance builds because their I-beam shape is reinforced into an H-beam profile, giving them increased strength and rigidity to withstand higher cylinder pressures and RPMs compared to standard I-beam rods. The assembly also includes pistons with a 3.898-inch bore size, ready for your chosen compression ratio and cylinder head combination. The 58-tooth reluctor wheel is included, which is standard for most LS engines, ensuring proper crank position sensing for your engine management system.

When assembling a performance engine, attention to detail is key. This rotating assembly is a critical component, and Eagle has a reputation for producing strong parts for these applications. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper balancing, assembly, and break-in procedures to ensure the longevity of your new engine.
