Here is a picture of a "near stock" setup on my jeep and then a picture of a TBT Hi-Steer setup so you can compare the difference. As AZ stated I did run the alumiflex long arm setup for a few years and I have been fairly critical of it because I feel it has significant short comings. However I have always been a fan of Troy's steering setup and wished I had went with it a long time ago. The reason I didn't was because he was doing shop installs only on it and I didn't want that. There are only a few people I trust working on my rig and one of them is me.
Sorry about the crappy pic of my steering, but I guess it's the best one I have. I am running the Rock Krawler Gen I steering setup made from 1.5" solid stock for the tie rod and 1.25" solid stock for the drag link. I am also running it on top of the knuckle for a little added clearance.
As far as Troy's setup goes you probably won't even have a need for running a steering stabilizer if you go the hi-steer route. The bracket you are referring to is what moves your trac-bar bracket from the front of the axle to the top of the axle. This puts the Trac-Bar/Drag Link geometry in perfect alignment and also moves it up out of the way.
