I don't think the lower eyelet is specifically made for the 575, as far as I know, It is a shock with a 2.25 stroke, but limited to only use 2 inches of it so the shock body does not contact the linkage. At least when I bottom out my shock with no air in it, it stops about a quarter inch from the end. The other day I was at my local shop and saw a 575 with a Fox coil on it, but I didn't get a good look at it.
Try it and let us know what happens. Good Luck.
