I'm running it with the carli diff guard and my half thuren/half carli suspension setup - AFAIK the only Carli part that would cause you clearance issues is the carli front trackbar.
The 1st 3 suspension modifications on my truck where the thuren swaybar, the synergy box brace, and the ATS. Going from stock to ATS was pretty noticeable and then closing the ATS almost all the way off really was the cherry on top for me when it came to steering dampening on the highway, construction zones, and on poorly maintained gravel roads. I didn't install the rest of the suspension for a while due to delays in getting everything, lining up the install/alingment, work/life stuff, etc.
I'm running a tweener size in 315/70R18 OpenCountry M/T's and once I got those heavy 36x13 M/Ts on there it felt like the stock dampener wasn't doing any dampening. It doesn't totally fix the radial pull like adjusting the nitrogen pressure in the Carli twin dampener setup can, however, I'm used to it with M/Ts and will likey go with A/Ts on the next set of tires when I go to 37x12.50. I like that it's neutral and balanced in its dampening both directions - Honestly if the setup wasn't so costly and wouldn't cost me losing some downtravel, I would get the Synergy tie-rod setup with two ATS dampeners on it. That said I also like heavier steering and closing down the ATS does give you some of that so it would be nice to be able to run two of them with each one running more open.
