Eagle is well-known for making strong internal engine components, and this Pro Street rotating assembly is a prime example of their work for Chevy LS engines. If you're building a naturally-aspirated LS for racing, this assembly is designed to handle the demands of that kind of use. It’s a complete package that brings together the key rotating parts you need to get your engine project moving forward.

This assembly features a 3.900-inch stroke crankshaft, which is a solid choice for increasing displacement and torque in your 4.8L or 5.3L LS engine. Paired with the crankshaft are 6.125-inch I-beam connecting rods. These rods are well-built for performance applications and connect the pistons to the crankshaft. The assembly also includes 3.780-inch pistons, which are sized to work with the crankshaft and bore of your LS engine. This combination of components is engineered to work together as a balanced rotating assembly, which is crucial for engine longevity and smooth operation at higher RPMs.

When you're deep into an engine build, having a reliable rotating assembly like this Eagle kit saves you time and ensures that your core components are matched correctly. It’s a significant step towards a powerful naturally-aspirated LS engine build. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
