If you can use your creativity you can make these work if you have round rack bars. I modified my entire factory FJC rack with these to make my tent, Rotopax and storage mounts. So if they will hold all that they will hold Maxx Traxx (or the cheap knock offs like mine). The have different configurations if this style doesn't fit your build.
