Jack stands don't work well with my frame height, and it's a pita to lift a 14 bolt FF up to the springs by myself, so I made a hitch/jack extender bar out of some scrap that I had. It slides into the receiver hitch and the up and down bar is adjustable by drilling another hole so it can fit many vehicles. It's easy now to swap axles or springs by myself; just lift the frame, swap, drop the frame back down. It also works to test my suspension for full droop because I have the full lift height of my jack to use to lift the truck, which is around 19" or 21" of jack lifting height or something like like. Now I need a front receiver, more ghetto fab to come... Cool, huh?
