Our new billet water pump pulleys have a 5.0" outside diameter, and a 1.925 inside depth. Available: natural (which can be powder coated), anodized  (red, blue, or black hard coat), or fully polished.  We also offer billet t-stat housings in matching colors.

NOTE: The red, blue, and gold anodized units are limited (until supplies last) as we will no longer offer these colors once they are gone.
