What is the primary function of a crankshaft damper?

A crankshaft damper helps to reduce torsional vibrations in the crankshaft. This can lead to improved engine longevity and smoother operation, especially in engines that are used for performance applications.

What does the '3-ring' design refer to?

The 3-ring design refers to the internal construction of the damper, which uses multiple rings to absorb and dissipate the torsional vibrations from the crankshaft more effectively.

What does the '61 key' specification mean?

The '61 key' refers to the external keyway size and configuration on the damper, which must match the crankshaft's keyway for proper installation and function.
