What is the purpose of a crankshaft damper?

A crankshaft damper, also known as a harmonic balancer, helps to absorb torsional vibrations that occur in the crankshaft during engine operation. This can lead to improved engine longevity and smoother running.

What does the '6 Percent OD' mean for this damper?

The '6 Percent OD' indicates that this damper is designed to spin 6 percent faster than the crankshaft. This overdrive can be useful for ensuring accessories like alternators or water pumps maintain adequate speed, especially in performance applications.

What is the benefit of an aluminum shell assembly?

An aluminum shell assembly is chosen for its lightweight properties compared to steel. This can contribute to overall weight reduction in the engine assembly while still providing the necessary function of vibration dampening.
