The rotating assembly of the 6.7L Cummins engine (2007.5–2018) includes all the major components that rotate to produce and transfer engine power. This consists of the crankshaft, connecting rods, pistons, wrist pins, and harmonic balancer. These parts work together to convert the linear motion of the pistons into rotational motion that drives the drivetrain. Built for durability, the 6.7L Cummins rotating assembly is designed to handle high torque and combustion pressure. In performance builds, components like forged pistons, billet rods, or balanced crankshafts are often used to increase strength and reliability.
Building engines the way the OEM factory should have in the first place.
