I don't want to tell you something that isn't true, but when I purchased them that's what I remember it saying. I did call them either yesterday or monday to clear it up and the guy said that they were the "old level 2's". I asked him if the one's I have are actually level 0's and he told me no... I specifically told him I had my invoice and told me I had old level 2's. he told me they changed the outer joint and the boot color changed to blue and now they call them 2.9's. beyond that... I can't say... I'm out of space concerning attachments or I'd stick that in for all to see...
