Eagle Chevy LS1 4.000in Crank 58 Tth Reluctor 6.125in I-Beam Rods 3.913in Pistons Rotating Assembly

Eagle is well-known for building robust engine components, and this Pro Street rotating assembly is a prime example of their commitment to performance. 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 brings together the core rotating parts you'll need to get your engine built.

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 it are 6.125-inch I-beam connecting rods made from strong 4340 steel, secured with 7/16-inch ARP 8740 bolts. These rods are built to withstand the forces generated in a performance engine. The assembly also includes 3.913-inch flat-top pistons made from forged 4032 DSS material, featuring a -5cc dish for optimal compression in many LS1 builds. These pistons come with plasma-moly file-fit rings, allowing for precise gap setting during installation to ensure a good seal. To top it off, King XP rod and main bearings are included, offering excellent wear resistance and performance for your engine's critical rotating components.

This rotating assembly is specifically configured for a 58-tooth reluctor wheel, common in many LS1 applications. While this assembly is built for performance, please note it is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures to ensure the longevity of your new engine build.
