Maybe I didn't order correctly, didn't read all the details etc, but these spacers didn't quite fit my ATV. The hub size on the ATV axles was larger than the countersink on the wheel spacers. Luckily I work with a group of mechanics so I was able to countersink the hole to match my trucks. I went this route, right or wrong, so I didn't have to wait for a replacement and possibly order the wrong one a second time. I don't recall seeing that dimension in the description, but I may have missed it.
