Hey Guys, I see that several people are using these to mount highlifts and such. I have a set that I bought new and painted gray to match the roof rack. It is a complete set, which is four towers. These are the ones that bolt/clamp directly onto the big round bar of the rack (runs front to back). I now have a set of Lowrider Max's so I will not be needing these. You could use two for a highlift and two for a shovel. Pics on request, just pm me. $35 for all four. They are hella strong. We carry a 16' canoe regularly at interstate speeds.
