This Scat crank is similar in design to the external crank offered in our assemblies, but it is internally (neutral) balanced in the front and rear. Running a crank that is neutral balanced will allow the use of a non-weighted front damper and a neutral flexplate or flywheel. This will eliminate the additional mass on those items. Replacing the damper or flexplate, if it's ever needed, becomes a simple procedure, and assures that the balancing is not affected. It's well known that under high rpm conditions, the crank on externally balanced engines is at risk of breaking much more than those with an internal setup.

To be perfectly clear, this ad is NOT for the stand-alone purchase of this item. This is an upgrade only available to customers that have purchased a rotating assembly or short block kit.
