Product Details

This is the Eagle Chevy LS3 rotating assembly, a complete package designed for serious performance builds. If you're putting together a powerful LS3 engine for racing, especially with nitrous or forced induction, this assembly is built to handle the stress. It includes a forged 4340 steel crankshaft, strong H-beam connecting rods, and custom pistons, all balanced and ready to go.

At the heart of this assembly is a 4.000-inch stroke forged 4340 steel crankshaft, known for its strength and durability under high loads. It's paired with 6.125-inch long H-beam connecting rods, which are a popular choice for their robust design and ability to withstand significant forces. These rods use 7/16-inch ARP 8740 bolts for a secure connection. The pistons are forged 4032 DSS units with an inverted dome design, featuring a -29cc volume and a 4.075-inch bore size, which helps achieve a specific compression ratio suitable for boosted applications. The assembly also comes with plasma-moly file-fit rings and King XP rod and main bearings, ensuring smooth operation and longevity.

This rotating assembly is a well-built foundation for a high-performance LS3 engine. It's important to note that this part is not CARB approved and cannot be shipped to California.
