My first order of this product arrived and it was plain white nylon bushings, not Neverfail bushings. It's a little suspicious because there's no "Lippert" written anywhere on the box, nor are there any instructions or papers. The replacement order also includes only nylon bushings and again no reference to a Lippert part. The packaging simply says "universal tandem axle kit". I'm sending them back and trying another source. Either they must be listed correctly, or the Neverfail sockets must actually be in the box.
