obx is not "name brand" is knock off Chinese stuff. On something hanging on the side of my nice high revving motor I do not want some unbalanced piece of "billet aluminum". Your best bet is a stock one which is a harmonic damper. Also OBX has the timing marks off and alot of times not even there. So you can't properly time your engine. As far as aftermarket goes ATI and fluiddampr are 2 great ones.
