I've been running it for 2 or 3 years now without a problem. It's like a heavy duty stock track bar with a slight bend on the axle end to allow more droop, then cut and sleeved to make it adjustable without having to disconnect one end to adjust it.
I've actually gone through 3 adjustables, the RE regular one (1600 I think), the RE heavy duty, and now the TeraFlex. I had the RE 1600 first and it was fine except there was a little bit of play that developed in the heim. Other than that I liked it. It was ruined in a wreck so I had them install the heavy duty one right when they first came out. The bracket didn't fit quite right and was a pain to get on, but I finally got it on. Then the bar would hit the diff cover all the time since I only had 3.5" of lift. So I sold it and bought the TeraFlex one. I'm the only person that I know of that has had that problem though with the RE HD unit. Maybe they changed it since I had it right after they came out with it. If I were going to buy one now I'd take a good look at the Skyjacker one first because it changes the mounting point to the top of the axle which makes it more parallel to the ground. So in short, I like my TeraFlex bar, would take a close look at the Skyjacker bar, and wonder about the RE bars since everybody loves them except me.
