Eagle Chevy 4.8/5.3 LS 4.000in Crank 24 Tth Rlctor 6.125in I-Beam 3.800in Pistons Rotating Assembly

When you're building a naturally-aspirated LS engine for racing, Eagle's Pro Street Rotating Assembly gives you a solid foundation. This assembly includes a 4.000-inch forged 4140 crankshaft, designed to handle the demands of performance builds. It features a 24-tooth reluctor wheel, which is standard for many LS applications. You also get a set of 6.125-inch 4340 I-beam connecting rods, which are well-built for strength and reliability. These rods come equipped with 7/16-inch ARP 8740 bolts, a popular choice for their durability and ease of use in performance engine builds.

The pistons included are forged 4032 material from MAHLE, measuring 3.800 inches in bore diameter. They feature an inverted dome design with a -16cc volume, which helps achieve a desired compression ratio depending on your cylinder heads. This assembly also comes with plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use. To complete the package, King XP rod and main bearings are included, offering robust protection for your crankshaft and connecting rods under high-stress conditions.

This rotating assembly is specifically intended for naturally-aspirated racing applications. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and assembly procedures.
