About this part

Product Details

This is the Eagle Chevy LS2/LS3 rotating assembly, featuring a 3.900-inch crankshaft, 6.125-inch H-beam connecting rods, and 4.065-inch pistons. This assembly is designed for high-performance applications, specifically for the LS2 and LS3 engine platforms. It's a well-built package intended for builders who are pushing their engines hard, whether for racing, forced induction, or nitrous use.

The core of this assembly is the Eagle crankshaft, forged from high-strength steel for durability under extreme loads. Paired with these are the 6.125-inch H-beam connecting rods, also forged for robust performance. H-beam rods are a popular choice for their strength-to-weight ratio, making them suitable for demanding builds. The pistons are sized at 4.065 inches, completing the set for a specific bore size. This rotating assembly comes with a 24-tooth reluctor wheel, which is important for engine management systems on many LS engines.

When assembling a performance engine, the rotating assembly is a critical component. Choosing a well-built, balanced set like this Eagle package helps ensure reliability and performance. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder and manufacturer's specifications for proper installation and balancing procedures.
