Track-Bar axle mount failure
I was looking surfing through the forum when I cam across the JKS ad of the axl brace and it left me a little worried of what the manufacturer has left in our hands after speaking with Jim from their Tech Support its not so much about how much this brace is but the fact the the ManCO. would leave a problem like this in our rigs and especially that I am not the only guy with an 07 on the road. I thought by not putting the extension bracket that som companies offer and by using the adj tracbar that I would be the exception to the problem of having a failure such as this. Has anyone experienced this situation before and went by the same concept as myself about the adj. tracbar ? What was your outcome let me know.
I have had adjustable trackbars (no brackets) on my 2" lift for 2 years without a failure, I think that is what you are asking?
There are a TON of threads on here where people chose the adj. bars over the brackets.

My front trac bar bracket broke 200 miles after I put on a Rubicon Express 4.5" long arm and a high steer. Mine broke as I rounded a corner in a residential neighborhood and there were cars parked on both sides of the street. I am still not sure how I didn't hit one as it was pretty wild for a moment.
I had it welded back on and had the Currie trac bar support added as well. I also had the rear bracket strengthened by increasing the welds. I now have about 1,000 miles and two days at Tellico on it. It seems fine. I am not sure if it would have happened with only the lift, but I a sure the high steer added to the stresses on it. Still, you would hope they would weld them better in the manufacturing process.

I broke my front track bar bracket a few weeks ago. I was going 30MPH down a busy road and almost caused an accident.
Anyway it finally failed after using the Skyjacker adapter bracket with the 4" lift at 15,000 miles.
Needless to say, I got rid of the adapter bracket and went with the JKS Adjust. TB. Hopefully this won't happen again. The way it was described to me, and it makes perfect sense, is that the adapter bracket that lift kits come with extend the mounting point of the trackbar to the axle housing up, which when the body and the axle move against each other provides a good deal of leverage to break the mount clear off.
Having said that IT IS WORTH THE MONEY to go with the adjustable trackbar. My Jeep hasn't driven right since the TB bracket broke off and my rig almost bounced itself apart.

If you put on an adjustable trackbar, you dont need the bracket. (on lower lifts)
One replaces the other.
The bracket is cheaper than the adjustable trackbar, and in effect lengthens the trackbar so you dont need an adjustable one (cheaper option included in some lifts to keep the price down) HOWEVER, adding a tracbar bracket at the axle end increses the leverage on the welds and overstresses them and cuases them to break.
the adjustable bar doesnt increase the lerage over the stock bar because it mounts in the same location.

There you go. Happy worded that much better than I did.
I agree, that is one of the newer type brackets and has several mounting points to spread out the force. I doubt you would have any difficulties with it.
The old type just slid into the stock bracket and relied on the welds from the factory to hold it in place, with a longer moment arm... Turns out that wasn't such a hot idea.
It has since been readdressed by a lot of companies.
TeraFlex, Currie, JKS all have substantially improved brackets available now.
Some require welding, Some do not.
In my own personnal opinion when it comes to my Jeep, it is a good idea to have it burned in. Even if i ended up with a bolt on, i would still have someone tack it on there permanently. I am sure without a doubt that the bolt ons work just fine, but my personnal preference is on the welded side.
