Eagle Chevy 4.8/5.3 LS 4.000in Crank 58 Tth Rlctor 6.125in I-Beam 3.780in Pistons Balanced Assembly

If you're building a naturally-aspirated LS engine for racing, a balanced rotating assembly like this one from Eagle is a smart way to start. This assembly includes a forged crankshaft, connecting rods, pistons, rings, and bearings, all balanced as a set. This means the critical rotating mass is already accounted for, saving you time and ensuring proper engine operation.

This assembly features a 4.000-inch stroke forged 4140 crankshaft, designed for strength and durability in demanding applications. It's equipped with a 58-tooth reluctor wheel, which is standard for many LS applications. The 6.125-inch I-beam connecting rods are made from strong 4340 steel and come with 7/16-inch ARP 8740 bolts for a secure connection. The pistons are forged 4032 DSS with an inverted dome design, measuring 3.780 inches in bore size, and include plasma-moly file-fit rings. King XP rod and main bearings are included to ensure smooth operation and proper oil clearance.

This balanced rotating assembly is a solid foundation for a performance LS build. Keep in mind 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.
