An anodized aluminum replacement to a steel problem.
Made from 6061 aluminum and silver anodized. This is a direct replacement to the Vortech steel retainer that often (and quickly) corrode or rust when the zinc coating breaks down.
Also added to the design is a centering extrusion so the retainer fits squarely into the pulley. Please note that this extrusion recesses 2.35mm into the supercharger pulley. If the supercharger shaft is not lower than the top of the supercharger pulley by this amount or more, it will not properly retain the pulley.
