I have installed a Teraflex leveling kit on my '14 Rubi, and after towing a trailer several weeks ago decided it would be a good idea to get some air bags. I am not exceeding the rating by any means, but the weight does squat the rear noticeably. This throws my headlights off, and affects handling.
The two trailers are a pop-up weighing in at a whopping 970 lbs, and 6' utility trailer (300 lbs) with a riding mower (650 lbs) that neither of which come close to the 2k tow rating even with two adults and two kids in the Jeep. In my situation bags seem to be the way to go.
Now the problem. The rear spacers for the Teraflex kit have this large stem that protrudes down into the coil. Does this pretty much screw me out of being able to use the bags? Would I just install the bag regardless and everything will be good to go? Maybe cutting the stem off would work?
I thought I would ask here to see if anyone else has gone down this path before I start firing off emails to Teraflex or spend hours chasing squirrels online looking for answers. In the ideal world I would just buy OME springs and call it done...
I was in the same boat back when I was running a rough country spacer lift and towing my pop up. I considered exactly what u mentioned but I had the same issue of the lines not being able to go up thru the spacers. My pop up wouldn't accept weight distribution as most small trailers won't. I just dealt with the squat until I upgraded my suspension to a rock krawler 3.5 x factor. Once you upgrade your coils you will realize how overly soft the stock springs are. I now tow an an even heavier light weight travel trailer at 2800 lbs dry and the rear hardly squats at all and pulls even better. The bags are a good idea if you can figure out how to make it work or just pick up a set of better aftermarket rear coils. If it still squats with aftermarket coils then you could easily add bags.
I asked the same question on another forum and the only response said it would work as an air line guide. There does appear to be a "puck" that installs atop the bag, I do wonder if that would rest against the spacer's stem making it feasible or if it would just eat up too much height within the coil.
Getting new coils would be awesome, but that would mean new tires along with a track bar/bracket along with all that other good stuff to get it set up properly. With a kid on the way, that's just not in the cards right now. Bags looked like a way to get by until I can swing the good stuff. Might have to just suck it up and live with the sag for a while longer.
