Yes, that would be a cam GEAR not just a cam, saying cams usually means a cam shaft you will never find a cam shaft for 50 bucks unless its from a junk yard. What you are looking at goes on the end of the cam shaft and has a timing belt wrapped around it. Big difference

 

sorry im mechanically inclined when it comes to internal stuff

 

Now it makes sense.... when I was lookin I only saw like 1 or 2 actuall cam shafts so I was confused as well.... However, buying AEM True Time cam gears and then getting the cam shaft re-ground at a machine shop could help out your power quite a bit....
