About this part

Product Details

Eagle is well-known for making strong internal engine components, and this rotating assembly is a prime example of their work for the Chevy LS7 engine. If you're building a high-performance LS7 for racing, especially with forced induction or nitrous, this assembly is designed to handle the stress. It’s a complete package to get your engine’s core rotating parts sorted.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, chosen for its strength and durability under high loads. Paired with this are 6.125-inch H-beam connecting rods, secured with 7/16-inch ARP 8740 bolts, which are a popular choice for their reliability in demanding builds. The pistons are forged 4032 DSS flat tops, featuring a -5cc dish to help achieve your desired compression ratio, and they come with plasma-moly file-fit rings. To ensure smooth operation and longevity, King XP rod and main bearings are included, offering robust protection for these critical components. This assembly also features a 58-tooth reluctor wheel, which is important for proper engine management on specific LS7 applications.

This is a comprehensive rotating assembly for serious engine builds. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
