Assuming you have a solid tie-rod, you really should be able to set it once and not have to adjust it again. This is certainly Rock Krawlers understanding of things and they do not have an adjuster - just a means to set it once and be done with it. I have run their tie-rod in the past and found it to work well.
That being said, I personally prefer to run a Currie tie-rod due to it's beefy factory like design, huge tie-rod ends and superior strength because of both. Of course, it isn't cheap but you get what you pay for.
