Sorry I never actually answered your original question. Perhaps someone here can give a better explanation or illustration b/c I'm not very techie & suck at creating diagrams,,,, but if you imagine your steering components as forming kind of a portion of a "Z" from the frame attachment to the wheels themselves, the drag link attaches at the tie-rod, which is the rod that moves the wheels when you steer. (the tie rod is the lower horizontal line of the "Z") Look at the drag link as the counterpart to the pitman that attaches at frame. When your front axle articulates, the drag link flexes (rather than breaking). There are companies that make HD steering assemblies for Discos but again, I haven't had the need. I figure I'll just run stock until I break something (probably a tie rod),,,mend it on the trail,,,and then order up something after-market. If you are concerned about this, you could get a tie rod from a junk yard & carry it as a spare in the event of damage and then look to upgrade. However, as I said, I would take Steve's advice on any RTE lift as he designed it and is going to know specifically what you need, why you need it, and have the custom designed parts on hand.
