If you're building a naturally-aspirated LS engine for racing, this balanced rotating assembly from Eagle is a solid choice. It's designed for Chevy 4.8L and 5.3L LS engines, providing the core components you need to get your build started right. This assembly includes a forged crankshaft, connecting rods, pistons, rings, and bearings, all balanced together as a set.

The heart of this assembly is a 4.000-inch stroke forged 4140 crankshaft, which is crucial for increasing displacement and torque. It's designed with a 24-tooth reluctor wheel, compatible with most LS engine management systems. The connecting rods are 6.125-inch long 4340 I-beams, known for their strength and durability in performance applications, and they come with 7/16-inch ARP 8740 bolts for a secure connection. The pistons are forged 4032 DSS inverted dome style, measuring 3.810 inches in diameter, and they include plasma-moly file-fit rings, giving you the flexibility to set your own ring gap for optimal performance. King XP rod and main bearings are also included, offering robust protection for your rotating assembly.

This assembly comes balanced from Eagle, which saves you a significant step and ensures the rotating assembly is ready for installation. This is a critical part of engine building, as proper balance reduces vibration and stress on the engine, leading to a longer lifespan and smoother operation. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
