They are very well designed and are very strong, but I just don't think the craftsmanship is there.  There's a lot of splatter on the welds, and while they may be strong, they're pretty ugly.  The paint is also substandard.  Mine started rusting almost right away- gotta pull them off this winter and repaint them.  It's just not the kind of thing I'd want to put on a nice, shiney new truck again.  If you're not concerned about aesthetics, I say go for it.  I also had some problems with the service I recieved when I ordered them, and have talked to others who have had similar problems.  If I had it to do over again, I'd probably either weld my own, or find a good local weld shop to make a set for me.
