All of the parts of the King screw jack are top of the line, including the machined and anodized aluminum base. It rides on a spherical rod end that allows the foot to sit flush with the ground despite uneven ground. Unfortunately, it wasn’t quite big enough to keep from sinking in the sand. When we got beached on our sliders in the rocks, we couldn’t use the King screw jack. More jacking points around the vehicle could have resolved this issue.
