7/16" is the factory size on our older rigs. At some point it was switched to 1/2" from the factory.
The frame rail itself is slightly wider at the frame eye hanger location in my experience. No shackle swing to clear. I don't believe it is wider everywhere but never had the need to verify that.
My crew cab was converted from 2wd to 4wd and I had to clearance the frame for this purpose.
