shipping box was great. But I think the flared part of the nut is too small. When I tightened the nut to factory specs, I found that the hole in the rim where the bolt goes is slightly wider. I would buy a different kind if I knew. It's still installed on the machine anyway and I can't do much about it, but I'd recommend trying to get a more accurate size of the nut you're removing. I replace them because the old ones have been on my car for 18 years. I believe in safe driving. I think it's a bit of a security trade-off. This is one of the few times I've had trouble with Revain's fit recommendations.
