I was out last night at the Tractor Supply store and saw some clevis shackel's that looked identical to the warns that I use and they were $13 bucks with some numbers on the side. I don't have them handy, but does anyone know what the rating numbers on the side of clevis shackels mean? It was WIL something if that rings a bell. I compared them to my warn's and the numbers were higher (making me think it was stronger but I've seen dumber things before) so I was wondering if anyone knows how clevis shackels are rated. Thanks.
