A tie rod flip is used for clearance and to keep the geometry correct on major lifts. The tie rod and drag link are removed, the holes in the knuckle (arm) are either enlarged and reamed (for a larger tie rod ends) or reamed so that the tie rods can be mounted on top of the knuckle. You also do the same to the drag link. The geometry for the steering is that you want the tie rods and the drag link running parallel to each other. On a lift the drag links angle increases (no longer parallel).
View attachment 45743. If you're not doing a major lift or extreme off roading you probability don't need. I would worry about getting a new frame.
