About this part

Product Details

This is the Eagle Chevy LS 4.8/5.3 rotating assembly, built for serious performance applications. It features a 3.800-inch crankshaft, 6.125-inch H-beam connecting rods, and 3.820-inch pistons, all designed to work together as a balanced unit for your LS engine. This assembly is intended for all forms of racing, including those using nitrous oxide or forced induction systems, meaning it's built to handle significantly higher stress than a stock setup.

The H-beam connecting rods are a strong choice for high-performance builds, offering excellent strength-to-weight characteristics. Paired with the precisely sized crankshaft and pistons, this assembly aims to provide a well-balanced rotating mass. Proper balancing is crucial in a performance engine to reduce vibration and ensure smooth operation at high RPMs, which is why a complete rotating assembly like this is often preferred for builds aiming for maximum power and reliability under demanding conditions. The 58-tooth reluctor wheel is also included, which is important for compatibility with many LS engine control modules.

When undertaking a build of this caliber, it's important to note that this assembly is not CARB approved and cannot be shipped to California. You'll want to ensure you have all the necessary supporting components for your engine build, including bearings, rings, and proper assembly lubricants. Consulting with a professional engine builder or referring to Eagle's specific installation guidelines is recommended to ensure optimal performance and longevity.
