Nope. Brand new in the box from MP. Another interesting thing about them is that out of the 16 rockers I bought, I discovered that 7 of of them were cracked. I discovered this after I had run them for a couple hundred miles and pulled them off to have them bushed. I saw what looked like a crack on one, then magged them all (I was working at a machine shop at the time). 7 of them were cracked. I still have them to remind myself how crappy MP parts can be. Can you say "lowest bidder"?
