Eagle Chevy 4.8/5.3 LS 4.000in Crank 58 Tth Rlctor 6.125in I-Beam 3.810in Pistons Rotating Assembly

This Eagle Pro Street rotating assembly is built around a 4.000-inch forged 4140 crankshaft, a solid foundation for a performance LS engine build. It's specifically designed for naturally-aspirated racing applications, meaning it's optimized for engines that don't use forced induction like turbochargers or superchargers. The assembly includes a 58-tooth reluctor wheel, which is crucial for proper engine management system operation on many LS engines.

You'll find 6.125-inch 4340 I-beam connecting rods included, which are strong and well-suited for the demands of racing. These rods are secured with 7/16-inch ARP 8740 bolts, known for their reliability under stress. The pistons are forged 4032 DSS units with an inverted dome design, featuring a -15cc dish to help achieve your desired compression ratio. They come with plasma-moly file-fit rings, giving you the flexibility to set proper piston-to-wall clearance for optimal performance and sealing. King XP rod and main bearings are also part of this comprehensive package, offering robust lubrication and wear protection.

This assembly is a significant step up for anyone rebuilding or upgrading their Chevy 4.8L or 5.3L LS engine for racing. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
