Product Details
If you're building a high-performance LS2 engine for naturally-aspirated racing, a strong rotating assembly is the heart of the operation. This Pro Street rotating assembly from Eagle is built to handle the demands of the track, providing a solid foundation for your build. It's designed to work with the LS2 platform, ensuring proper integration into your engine project.
Eagle starts with a 4.000-inch forged 4140 crankshaft, known for its strength and durability under high stress. Paired with this are 6.125-inch I-beam connecting rods made from robust 4340 steel, secured with 7/16-inch ARP 8740 bolts for reliable performance. The assembly includes 4.000-inch forged 4032 DSS pistons with an inverted dome design and a -15cc volume, which are ideal for naturally-aspirated applications. To ensure a proper seal and efficient operation, it comes with plasma-moly file-fit piston rings. For critical bearing surfaces, King XP rod and main bearings are included, offering excellent wear resistance and smooth operation.
This assembly is specifically configured for a 58-tooth reluctor wheel, common on many LS2 applications. Please note that this assembly is not CARB approved and cannot be shipped to California. It's important to verify all component compatibility with your specific engine build and local regulations before installation.
