Don't buy them. Installed them on a brand new wheelset and followed the recommended instructions without using an impact wrench. I only used a 1/2" ratchet. They had about 6 weeks and the big tires and wheels caused the passenger front wheel bearing to fail. I went to shoot them with the same ratchet. Won't move so have i used a breaker to loosen them half went through the lugs and heard a loud pop when i loosened and looked down and it broke as shown in the picture.if i don't use a wheel that often in my life had switched I would have thought I screwed something up. Not this case. Other reviews have said the same thing. Much weaker than Chinese metal. Just pay the extra money and get a quality set, not that cheap Revain crap. You will thank me later
