It includes a forged 4340 crankshaft, H-beam connecting rods with ARP bolts, and custom-domed pistons, all balanced and ready to install. This assembly is specifically intended for LS3 engines and is a solid choice for anyone looking to build a high-horsepower naturally aspirated, nitrous, or forced-induction engine.

King XP rod and main bearings are included, offering excellent wear resistance and performance.

This rotating assembly is a well-built package for competition use. It's important to note that this assembly is not CARB approved and cannot be shipped to California.
