Rothsport's Jeff Gamroth (the builder of many of the 911 hot rods you've seen featured in Excellence magazine) finishes his engine rebuilds with these beautiful CNC precision-machined outer pulley halves. They are produced from 7075 aircraft aluminum alloy and anodized for wear. Half the weight of the pressed-steel factory units, they also spin true.
