Well, I actually had one and removed it. You are better off putting your money toward ram assist such as ******* Ram or PSC.
The bearing race gets chewed up quickly. Personally, I suspect it is because the needle bearing and race are unsealed, allowing dust and dirt to get in and grind up the race. If I can find my pics of that, I will try and post them. I think Synergy will just say that you have to service the bearing a lot more frequently (remove, clean and re-lube).
The other thing is that I saw someone bust their sector shaft with minimal effort on the Rubicon trial last summer and they had this brace installed!
Installation is slightly tedious getting the smaller nuts and bolts into place but completely terrible.
What stinks about the install is that Jeeps and these (track bar) these brackets are not perfectly aligned with each other at the upper track bar bolt. If you do not have ovaled out holes in your frame side track bar mount, you might after installing the track bar brace portion. In other words: there is no going back if you install it. You need to have all of the bolts really loose to be able to work the upper track bar bolt through. Once you tighten everything up, is when the hole gets ovaled out because the synergy bracket is a lot thicker and stronger.
The Sector shaft brace portion also hits on some of the larger springs out there like AEV for example. After ditching the sector shaft brace portion, I trimmed the little wings that stick out of the track bar brace where the sector shaft brace attaches.
