AVERAGE RATING OF 0 0 of 5 Stars!

This series is designed to withstand the extreme pressures encountered when using a blower (Roots-type supercharger).  Lunati Signature Blower Crankshafts have .140" radii on the rods and mains.  They also have dual keyways, 3/4-16 threads in the nose, and the flange is drilled to either 1/2" or 7/16".  There are 7/8" lightening holes in the #2, 3 and 4 rod journals.  The #1 rod journal is not drilled in order to provide extra strength on the front of the crankshaft.  Rod and main bearings must be chamfered on all Signature Blower Series Crankshafts.
