Product Details
Eagle is well-known for making strong internal engine components, and this Pro Street rotating assembly is a prime example of their work for Chevy LS1 engines. If you're building a naturally-aspirated race engine, this assembly is designed to handle the demands of that kind of performance. It's a complete package that gives you the core rotating parts you need to get your LS1 build underway.
At the heart of this assembly is a 4.000-inch forged 4140 crankshaft, built for durability. It's paired with 6.125-inch 4340 I-beam connecting rods, which come equipped with 7/16-inch ARP 8740 bolts for a solid connection. The pistons are forged 4032 DSS with an inverted dome design, measuring 3.903 inches in diameter, and they include plasma-moly file-fit rings. To ensure smooth operation and proper bearing support, King XP rod and main bearings are included. This assembly is specifically configured with a 24-tooth reluctor wheel, making it suitable for many LS1 applications.
When putting together a high-performance engine, the rotating assembly is critical. This Eagle Pro Street package provides well-built components that work together, saving you time sourcing individual parts. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or refer to manufacturer instructions for specific installation details and any other components you might need to complete your build.
