Notes:
Non-Knurled ball joints recommended for replacing non-knurled ball jointsDue to these ball joints being tight tolerance, metal on metal ball joints, proper fitment is critical. Using the wrong style of ball joints can cause significant steering issues. We always recommend installing non-knurled ball joints until non-knurled ball joints are no longer a press fit into the axle end forging bores. If your axle end forging bores have been enlarged to the point that non-knurled ball joints are no longer a press fit, knurled ball joints are required.
Use of the improper ball joint style for the axle housing voids our lifetime warranty. It is up to the installer to verify the proper ball joint style is being used.
Compatible with RCV axle shafts

Beautiful but…
Size: 48in, Color: 3tier
I have bought a half dozen of these shelves over the years and installed them in my own home and family members homes. They are beautiful once they are up. The quality of the pipe and wood are great, heavy duty. BUT Somehow I seem to forget that the installation is a complete nightmare-borderline not worth it. The pipe never likes to line up properly and when it does it’s just not tight leaving the whole thing feeling wobbly. Once installed it is very beautiful and sturdy. The other part I also seem to forget is that the anchors are complete and utter crap! Save yourself the frustration and TOSS THEM immediately. Its a huge waste of time attempting to use them and your so pissed off by the time you realize it that you almost don’t even want the shelf anymore😂 In summary- Beautiful, quality shelf but buy your own anchors and round up you patience prior to install.

I like to have a three-dimensional wall shelf at home. I can display plants, photos and other items well. It is great. I haven't taken care of it yet. I need to put more beautiful items. Oh, by the way, it is of good quality. It is a little heavy. The merchant provides expansion screws for hanging it on the wall. It is also very simple to assemble... I am very satisfied with the effect and I like it very much.

Great Accent Piece
Size: 48in, Color: 3tier
Industrial looking with wide shelf space. We were looking for a functional accent piece that we can also put things on. This new addition has been more than perfect. It provides a rustic feel and it has the industrial bars that holds the shelves which is the best.
Very sturdy, please make sure to assemble on studs this piece is heavy. It looks really good in our living area.
