About this part

Product Details

If you're building a high-performance Chevy LS3 engine, this Eagle competition rotating assembly is a solid foundation. It includes a 4.000-inch forged 4340 steel crankshaft, 6.125-inch H-beam connecting rods with 7/16-inch ARP 8740 bolts, and 4.065-inch forged 4032 DSS pistons with an inverted dome design. This assembly is specifically designed for the 58-tooth reluctor wheel found on LS3 engines.

The components in this kit are well-built for demanding use. The forged 4340 steel crank offers strength for high-RPM operation, while the 6.125-inch H-beam rods are a popular choice for their balance of strength and weight. The 4.065-inch pistons feature a -29cc inverted dome, which is crucial for achieving the correct compression ratio with specific cylinder heads. This assembly also comes with plasma-moly file-fit rings and King XP rod and main bearings, ensuring proper lubrication and reduced friction.

This rotating assembly is intended for racing applications, including those using nitrous oxide or forced induction. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to consult with your engine builder to ensure all components are compatible with your specific build goals and cylinder heads.
