I might have to test out whether or not I can jack her from the stock steps. Hadn’t thought about that capacity use.
I wouldn't do that. The stock steps I have are bolted to the body. If a slight bump can dent these steps, as I have already done, I think a hi-lift jack would really put a dent as you try to lift a couple thousand pounds. These full size trucks are about 6k pounds, and lifting at the center of rig (between the tires) means you're lifting a good deal of that weight. Take a look under your body to see how these steps are bolted to the body.
I would recommend getting the Hi-lift tire adapter. The whole point of jacking up a rig is to get something under the tire, or if the tire is flat, you can still mount to the tire lift it and stick a few rocks, or better yet a Jack-stand, under the axle.
At any rate, I know for sure the stock steps are not strong enough, as they are only mounted to the body.
