Barely fit the hubs of my 2004 Grand Cherokee. Can't point the finger directly at the product there, it is 17yrs old and the hub lips have some rust swelling. BUT. I can blame the product for being useless. I could not fit a 1/2" drive 13/16" impact socket in the recessed hole. Or a standard 13/16". Or a 3/8" drive 13/16". OR A THIN WALL 3/8" DRIVE SOCKET. Well, technically the thin wall fit 2 of 5 holes on one spacer (never even bothered to check the other 3 spacers, didn't see the point), so that screams of poor quality control and a machining process may have been missed. None the less, If I can't get a socket in there, how am I supposed to mount it?! Useless to me. Returned. I was warned in forums of cheap "internet" spacers. I'll pay twice is much for a known name from a known 4x4 vendor, but I am willing to bet she'll bolt right on without issue.
