Ran them on my 01 XJ, made a huge difference in the way it handled. You will have to strip the factory rails down to bare metal. I've used this while building the bed on my MJ, and it works pretty good. Spray both the frame rails and the inside of the stiffeners before you put everything in place and start welding.
My only complant with the TNT stiffeners was it was really hard to get the welder into a good position to weld the outer edge right. I ended up spending a couple hours drilling a bunch of holes in them for plug welds to get a little better hold. If I had to do it again(and I will be on my 96) I'd go for the HD Offroad stiffeners. They are a little thinner(10gage/ just a little more than 1/8"), but they are cheaper and already have the holes for plug welds(allbeit a cubic butt ton).
