Me too... all suspension and steering related as well... along with Artec and LetzRoll, again, just in suspension/steering.
My opinion is that no one manufacturer has the "mack-daddy" setup, so I mixed up with what i believe to be the best for my requirements.
Guessing you are in the same boat.
I did not mean to offend you with my assessment earlier and make you feel the need to defend your purchase.
We all buy what we buy for different reasons, I was simply letting folks know why spherical/Johnny Joint and the MC/Synergy joints are designed the way they are.
Take care all and have a merry Christmas... I'm off to a seasonal party.

No offense taken. Just trying to put all options on the table so Jeepers can make better & more knowledgeable decisions. In the end, people are going to buy what they are going to buy....
MetalCloak was at the top of my list because I wanted to stick with rubber bushings on both ends. The J-axis I felt allowed for better flex without having to compromise the weak axle control arm brackets.

By keeping all of the bushings OEM/OEM-like, you can still evenly distribute the stress amongst all of the axle and frame side *control arm* mounting points as well as the trackbar mounting points vs having it all come down to 1 or 2 weakest links, in this case the front or rear trackbar mounting brackets.
If you just take the rear axle / rear frame for example, OEM/OEM-like bushings you more evenly distribute stress amongst 4 control arm bracket mounting points and 2 trackbar mounting points = 6 points total.
If you install control arm joints with too much give, then essentially you're directing all of that additional stress to the 2 trackbar mounting points.
Stress distributed more evenly across 6 points (control arm + trackbar) vs. 2 points (trackbar only).......
I'll take the 6 points. If I have a choice of losing 1 control arm or the trackbar as a result of a snapped bracket, I'll opt for losing the control arm.

I was going to leave this post alone, but it seems that you have fallen victim to one of your own complaints…
Having said all that, I like the JKS arms, and, a million years ago when they first hit the market I strongly considered them due to the fact that they used OEM bushings while incorporating a means to allow the rotational forced be mitigated. They were the best thing on the market at the time if you wanted rubber bushings.
There are now other options out there with rubber on both ends, that cost less.

Not to get in the middle of the e-battle - but I really don't see how the CA joints help combat lateral movement and relieve stress from from the TB bracket as DJI states .
You ever remove your TB and push the side of your jeep? It moves pretty damn easy. If they are aiding the TB, it's minimal.

Yep. Maybe if you had the stock rubber bushings things would be more stiff just because they don't move as easily as something like a rock krawler ball joint type. Regardless the track bar is meant to hold all of the lateral movement.
Sort of scary that the whole integrity of the jeep is held together with one little bar

This quoted comment right here and Mr. Ripper's implosion of his already beefed up rear axle trackbar, which in my view is a result of his failed RK joints allowing too much give thus allowing a larger portion of lateral stress to go to the trackbar mounting points, is all that I need.
Don't need to prove nuffin' to myself here.....proof was already shown.
Think 3 dimensionally, x-y-z axis. X axis offering 360 movement. Y axis limited by shocks, sways, bumpstops. Z axis is where you want the firmer joint. So easy to see that even the GEICO caveman can do it LMFAO.
Next.

I haven't really thought of reason my bracket ripped off. Your reasoning seems very logical though. Hmmmm
