Eagle Chevy LS2 4.000in Crank 58 Tth Reluctor 6.125in I-Beam Rods 4.005in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly gives you the core components to rebuild or upgrade your Chevy LS2 engine. You get a forged 4.000-inch crankshaft, a set of 6.125-inch I-beam connecting rods with 7/16-inch ARP 8740 bolts, and 4.005-inch forged 4032 pistons with an inverted dome design. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get you started.

This assembly is specifically designed for naturally-aspirated racing applications. The 4.000-inch stroke crankshaft is forged from 4140 steel for strength, and it features a 58-tooth reluctor wheel for LS2 engine management systems. The 6.125-inch I-beam connecting rods are made from robust 4340 steel, paired with reliable ARP 8740 bolts to handle the stresses of performance use. The 4.005-inch pistons are forged from 4032 aluminum, a material known for its good thermal expansion properties, and feature an inverted dome to achieve a specific compression ratio when paired with the right cylinder heads. The included plasma-moly file-fit rings allow for precise gapping to match your engine's bore and intended use, while the King XP bearings are well-regarded for their performance in demanding conditions.

This rotating assembly is a solid foundation for a high-performance LS2 build. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer specifications for proper installation and assembly procedures.
