Product Details

This Eagle Pro Street rotating assembly starts with a 3.800-inch stroke crankshaft, specifically chosen for its balance of displacement and RPM potential in Chevy LS 4.8L and 5.3L engines. The 6.125-inch I-beam connecting rods are well-built for the stresses of naturally-aspirated racing, offering a solid link between the crankshaft and pistons. These rods are paired with 3.810-inch pistons, completing the core of this assembly.

Designed for naturally-aspirated racing applications, this rotating assembly is a robust foundation for building a performance LS engine. The Pro Street designation indicates a focus on durability and performance for engines that will see regular track use or spirited driving without forced induction. Eagle has a reputation for producing reliable engine components, and this assembly reflects that commitment to quality for demanding builds.

When assembling an engine with this rotating assembly, ensure all components are properly balanced by a professional machine shop to match your specific application and intended use. This is a critical step for achieving optimal performance and longevity. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult your vehicle's specific service manual for detailed assembly procedures and torque specifications.
