Item arrived safe and sound with all parts. A plus for this setup, as with other manufacturers, would be a small amount of thread-locking solution for the top and bottom bolts with a flared flange assembly threaded for a screw-in ball. This is after installing the hex bolt and flange nut. from the factory is used for the initial opening and expansion of the part that enters the metal opening of the tailgate. It works without it, but why take the risk. It was a little unclear from the instructions and videos what exactly happens when installing the flare flange assembly. what is dragging on. I have understood. The product works very well. I would buy this product again or encourage others to buy it.
