Bought for my 15 year old Challenger. I've had non-original wheels for 22 years. I was a little nervous about going to a soccer game in San Francisco with no airlocks. My jeep has petrol wheel locks. So I did a little research, ordered (Challengerforumz) and my favorite wheel and tire shop delivered them. He told me that he had never seen such wheel locks! He said that every ledge is a castle! He laughed and told me never to lose the key because I would screw it up lol! I felt great. I will buy the same locking system for my jeep!
