No, it won't fit. Well, that's not exactly true. Yes, it will fit over the frame and drop down far enough but the mounts won't line up and you will find that the tunnel is quite wide as well. Of course you can make one work, just make up a new set of mounts. Oh, and the reason I know this is because I bought one of the tanks to try out on one of the 550s I have here. I bought about a half a dozen tanks to try out and ended up going back to the stock tank and modifying it.
