Have you tried getting a PJ, Goferit, 4xDoc, or other aftermarket heavy duty tie rod?
Looking at the pic, I would say its not real applicable to many Jeeping applications (like rockcrawling). I have rarely bent my tie rod on that side - its moslty been in the middle or on the passenger end. From what I can see in the photo, it gives absolutly no protection to the passenger side of the tie rod. Well...unless you run a D44 or other axle with a centered pumpkin and not an offset like the D30.
IMO take your $160 and go buy a good tie rod. If you want a diff guard, they are out there also.
