About this part

Product Details

If you're building a naturally-aspirated LS engine for racing, a well-balanced rotating assembly is crucial for performance and durability. This Eagle Pro Street rotating assembly is designed for that purpose, providing the core components needed to get your LS engine project underway. It's built around a 3.800-inch stroke crankshaft, paired with 6.125-inch I-beam connecting rods and 3.810-inch pistons, creating a robust setup for demanding applications.

Eagle has a reputation for well-built engine components, and this assembly is no exception. The Pro Street line is specifically geared towards naturally-aspirated racing use, meaning it's engineered to handle the stresses of high RPM and significant power output without the added complexity of forced induction. The I-beam connecting rods offer a strong balance of strength and weight, suitable for many performance builds. This assembly is a solid starting point for anyone looking to rebuild or significantly upgrade their Chevy 4.8L or 5.3L LS engine for track use.

When assembling an engine, precision is key. This rotating assembly comes with the crankshaft, connecting rods, and pistons, but remember that bearings, rings, and fasteners are typically sold separately. It's also important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always consult your engine builder or a qualified mechanic for specific installation requirements and recommended complementary parts to ensure optimal performance and longevity for your build.
