Originally they were made here in the U.S. Now they are made in Japan and imported. The 2nd batch that was made here was machined improperly and the rear toe wasn't equal from one side to the other. I believe this has been corrected in the Jap version. Ran it in my 415 for one season. Worked well but once you hit a dot hard the arms bend very easily. If they made a plastic graphite version I would definitely try it again.!
Just my 2$
