About this part

Product Details

This Eagle Competition Rotating Assembly starts with a 4.125-inch forged 4340 crankshaft, a solid foundation for building a serious LS7 engine. The crankshaft is designed with a 24-tooth reluctor wheel, essential for proper engine management on many LS-based applications. This assembly is engineered for the rigors of racing, including setups that utilize nitrous oxide or forced induction, meaning it's built to handle significant stress and power.

Complementing the crankshaft are 6.125-inch H-beam connecting rods, known for their strength and reliability under high loads. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability and consistent clamping force. The pistons are forged 4032 Mahle units, featuring a -8cc flat top design with a 4.125-inch bore, which works with the crankshaft to achieve the desired displacement. They come equipped with plasma-moly file-fit rings, allowing for precise ring gap setting to optimize performance and sealing.

To ensure smooth operation and durability, the assembly includes King XP rod and main bearings. These bearings are designed to handle the increased loads and heat generated in high-performance engines. This is a comprehensive rotating assembly aimed at builders looking for a well-matched set of components for a powerful LS7 build. Please note that this assembly is not CARB approved and cannot be shipped to California.
