The forged 4340 crank and H-beam rods are strong choices for engines pushing beyond stock power levels.

This assembly also comes with King XP rod and main bearings, which are designed for high-performance use and offer improved durability. This is a complete rotating assembly, meaning all the core components you need to get your short block started are included in one package.
