Eagle Chevy LS1 4.000in Crank 24 Tth Reluctor 6.125in I-Beam Rods 3.898in Pistons Rotating Assembly

If you're building a naturally-aspirated racing engine for your Chevy LS1, this Eagle Pro Street rotating assembly is a solid foundation. It includes a forged 4.000-inch crankshaft, 6.125-inch I-beam connecting rods with ARP 7/16-inch bolts, and 3.898-inch pistons designed for a -15cc inverted dome. This assembly is specifically configured with a 24-tooth reluctor wheel, common for many LS1 applications.

The crankshaft is forged from 4140 steel, offering the strength needed for demanding racing conditions. The connecting rods are made from robust 4340 I-beam forgings, paired with reliable ARP 8740 bolts to ensure they hold up under high stress. The included pistons are forged 4032 DSS with an inverted dome design, and they come with plasma-moly file-fit rings, allowing for precise gap setting during assembly. King XP rod and main bearings are also included, providing well-built lubrication surfaces for the crankshaft and connecting rods.

This assembly is intended for racing use and is not CARB approved, meaning it cannot be shipped to California. Ensure you have all necessary supporting components for your engine build, as this is a core rotating assembly.
