I have the Superrunner Steering setup, and it is great. It nearly eliminated all of my bumpsteer, and I have equal turning in both locking directions. Alignment is in place, and I've never needed to adjust it.
I initially bought mine 8 years ago, delicately-used, from a guy on DezertRangers. They come up from time to time, and bolt right into place. Service is easy with the greasable fittings, and this is on ~ 5.5" coil (with other lift components). I used a standard 4" drop pitman arm (not the Skyjacker 6" Extreme Drop #FA006 or whatever), and it performs well on & off road.
For my particular setup, like Legosm, I need ~another additional 1-1.5" plate drop on my centerlink portion where my tie-rods pop in. This is for me to achieve exact geometry (look at the Tech Library for TTB Steering), but this is more than close enough. It's a vast improvement over the old inverted Y link stock setup, especially since I'm on 35" tires.
For good steering, look up Stonecrusher steering on TRS. Here's an example of one of the threads, showing the setup:

If I were in your shoes, I'd be doing this if I couldn't find the Superrunner kit.
