When I upgraded from F150 to F250 I had to purchase new rails, which turned out to be 4-bolt. The F150 used 10-bolt, go figure. Anyway, have had no problems with the 4-bolt setup. They are pretty massive, 3/4" I think. I was leery at first, but it was nice having to drill six less holes in the bed. The main thing is to be certain the frame brackets are correct for your truck.
