About this part

Product Details

If you're building a high-performance Chevy LS7 engine, this Eagle Competition Rotating Assembly is a solid foundation. It includes a forged 4.000-inch crankshaft, 4.125-inch flat-top pistons, and 6.125-inch H-beam connecting rods, all designed to handle the demands of racing applications, including those using nitrous or forced induction.

The crankshaft is forged from 4340 steel, known for its strength and durability under high stress. The pistons are forged from 2618 aluminum and feature a -4.6cc flat-top design, paired with plasma-moly file-fit rings for a good seal. The H-beam connecting rods are also forged and come equipped with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in performance builds. This assembly also includes King XP rod and main bearings, which offer improved performance and durability over standard bearings.

This rotating assembly is specifically configured for a 24-tooth reluctor wheel, common in many LS engine applications. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting components and expertise for installation, as this is a critical part of your engine's internal structure.
