About this part

Product Details

Starting with a forged 4.000-inch stroke crankshaft made from 4340 steel, this Eagle rotating assembly is built for serious performance, especially in racing applications that might use nitrous or forced induction. The crankshaft features a 58-tooth reluctor wheel, which is standard for many LS-based engines, ensuring compatibility with your engine management system. This assembly is designed to handle the stresses of high-output engines, making it a solid foundation for a performance build.

Complementing the robust crankshaft are 6.125-inch H-beam connecting rods, known for their strength and durability under load. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their reliability in high-stress environments. The pistons are forged from 4032 aluminum and feature an inverted dome design with a -29cc volume, which helps achieve a desired compression ratio when paired with appropriate cylinder heads. They come with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. King XP rod and main bearings are included, offering improved lubrication and wear resistance for critical rotating components.

This complete rotating assembly is a significant step up for anyone looking to build a powerful LS2 engine. It includes all the core components needed to rebuild or upgrade your engine's short block. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult manufacturer instructions for proper installation and break-in procedures.
