Product Details

If you're building a naturally-aspirated LS engine for racing, this Eagle Pro Street rotating assembly is a solid option. It's designed for the Chevy LS2 and LS3 platforms, giving you a strong foundation for a high-performance build. This assembly includes all the core components you need to get your engine's bottom end put together, saving you time and ensuring compatibility between critical parts.

At the heart of this assembly is a 4.000-inch forged 4140 crankshaft, built to handle the stresses of racing. Paired with it are 6.125-inch I-beam connecting rods made from strong 4340 steel, secured with 7/16-inch ARP 8740 bolts for reliable performance. The pistons are forged 4032 DSS flat-tops with a -5cc dish, designed for a 4.040-inch bore. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your specific engine build. To top it off, King XP rod and main bearings are included, known for their durability and performance in demanding applications.

This assembly is specifically configured for a 58-tooth reluctor wheel, common on many LS applications. Keep in mind that this rotating assembly is not CARB approved and cannot be shipped to California.
