Eagle is well-known for building solid engine components, and their Pro Street Rotating Assemblies are a prime example of that expertise. If you're putting together a naturally-aspirated LS1 engine for racing, this assembly is designed to handle the demands of that kind of use. It's a complete package that gives you the core rotating parts you need to get your build started right.

At the heart of this assembly is a 4.000-inch forged 4140 crankshaft, built for strength and durability. 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 under stress. The pistons are forged 4032 DSS with an inverted dome design, measuring 3.905 inches in bore size, and come with plasma-moly file-fit rings. To ensure smooth operation and longevity, the assembly includes King XP rod and main bearings.

This rotating assembly is specifically configured for LS1 engines with a 58-tooth reluctor wheel. It's important to note that this assembly is not CARB approved and cannot be shipped to California.
