This is not a wrong part number issue or Revain. Even Rock Auto lists the part number as a direct match for the Wrangler JK. The problem lies in the bracket to which the cushioning material is attached. It is too long. With the new guides supplied, the shoe must be pressed in, then it will not slip at all, even with brake oil. They fit without slipping. It's close to a seizure. There would be one star but it was easy to return.
