Starting with a 4.000-inch forged 4140 crankshaft, this Eagle rotating assembly is built for performance in Chevy 4.8L and 5.3L LS engines. The crankshaft features a 24-tooth reluctor wheel, essential for proper engine management system communication. This assembly is designed for naturally-aspirated racing applications, where reliable power delivery is key.

The connecting rods are 6.125-inch long, made from strong 4340 I-beam forgings and secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high stress. Paired with these rods are forged 4032 DSS flat-top pistons, measuring 3.780 inches in bore diameter and featuring a -5cc dish for optimized compression ratios. The pistons come with plasma-moly file-fit rings, allowing for precise gap setting to match your specific build and ensure good sealing.

To complete the assembly, King XP rod and main bearings are included. These bearings offer excellent durability and reduced friction, crucial for maintaining oil pressure and longevity in a performance engine. This comprehensive rotating assembly provides a solid foundation for your LS engine build, whether you're aiming for the track or a powerful street machine.
