Product Details
The 6.125 inch H-beam connecting rods in this Eagle rotating assembly are forged from 4340 steel, a strong material chosen for its ability to handle the high stresses found in performance LS engines. This assembly is specifically balanced for Chevy 4.8L and 5.3L LS applications, featuring a 3.800 inch stroke crankshaft and 3.780 inch pistons. This combination is well-suited for building a robust engine for racing, including those that will utilize nitrous oxide or forced induction systems.
Eagle has put together this competition-grade rotating assembly with parts that are known for their durability under demanding conditions. The H-beam rod design is a popular choice for high-horsepower builds because it offers a good strength-to-weight ratio, helping to keep reciprocating mass manageable while providing the necessary support. The crankshaft is designed to handle the increased cylinder pressures and rotational forces that come with boosted or nitrous-fed engines, ensuring reliable operation when you push your LS motor hard.
When assembling your LS engine with this rotating assembly, pay close attention to bearing clearances and proper torque specifications as outlined in your service manual. This kit is intended for serious performance builds and is not CARB approved, meaning it cannot be shipped to California. Ensure you have all necessary supporting components for your engine build, as this is a core rotating assembly.
