Top off your new BOPORT head or cam install with one of our new BOPORT cam gears! These allow fine tuning of your new cam to maximize power or shift the power curve lower or higher in the rpm range. Also these allow degreeing of your cam if desired to our recommended intake lobe centerline angle. Also these gears feature a built in belt guide on the back so you can ditch the rusty and usually bent sheet metal factory piece behind factory gears. These are cnc machined from billet 6061 aluminum anodized black for a clean look and corrosion resistance. A new stainless steel bolt  with flanged head is included so you can throw away the stock rusted bolt and washer that never seems to center correctly. Available in square tooth (stock style up to 1988 year) or round tooth (1989 and up). Round tooth is preferred for performance use, and we sell the conversion kit also to convert your pre-1989 engine to a round tooth setup separately.
