Eagle Chevy 4.8/5.3 LS 4.000in Crank 24 Tth Relctr 6.125in I-Beam 3.810in Pistons Balanced Assembly

This Eagle Pro Street balanced rotating assembly is built around a 4.000-inch forged 4140 crankshaft, featuring a 24-tooth reluctor wheel for your Chevy 4.8L or 5.3L LS engine. This is a solid choice for naturally-aspirated racing applications where reliability and performance are key. The assembly comes balanced from the factory, saving you a significant step in the engine building process.

The connecting rods are 6.125-inch long, made from strong 4340 I-beam forgings and secured with 7/16-inch ARP 8740 bolts, which are known for their strength and durability under stress. Paired with these rods are forged 4032 DSS pistons with a -5cc flat top design, measuring 3.810 inches in bore size. These pistons are designed to work with the included plasma-moly file-fit rings, allowing for precise ring gap setting during assembly. King XP rod and main bearings are also included, offering robust protection for the rotating assembly.

This balanced assembly is designed for performance builds and is not CARB approved, meaning it cannot be shipped to California. Ensure you check all local emissions regulations before purchasing. This kit includes the crankshaft, connecting rods, pistons, rings, and bearings, providing a strong foundation for your LS engine project.
