Eagle Chevy LS2 4.000in Crank 58 Tth Reluctor 6.125in I-Beam Rods 4.005in Pistons Rotating Assembly

Eagle is well-known for building strong rotating assemblies that can handle serious performance applications. This Pro Street rotating assembly is specifically put together for naturally-aspirated racing use, giving you a solid foundation for a high-performance engine build. It’s designed to be a complete package, so you can spend less time sourcing individual components and more time on the build itself.

At the heart of this assembly is a 4.000-inch forged 4140 crankshaft, chosen for its strength and durability under high stress. Paired with this are 6.125-inch I-beam connecting rods made from 4340 steel, which are secured with 7/16-inch ARP 8740 bolts for reliable clamping force. The pistons are forged 4032 DSS flat-tops with a -5cc dish, measuring 4.005 inches in bore size, and they come with plasma-moly file-fit rings, allowing for precise gap setting during installation. This combination is built to handle the demands of racing without compromise.

To ensure smooth operation and longevity, this assembly includes King XP rod and main bearings. The crankshaft also features a 58-tooth reluctor wheel, making it compatible with specific LS engine management systems. Please note that this assembly is not CARB approved and cannot be shipped to California. It's a robust option for anyone looking to build a powerful, naturally-aspirated LS engine for the track.
