I’m towing a small travel trailer with a Jeep Wrangler with a 1-1/2” TeraFlex suspension lift kit. I made the mistake of not testing a fully loading trailer before heading out on a road trip. Just before leaving I filled the fresh water tank and found that it is far enough forward that it’s giving me too much squat. I think an air lift system is the way to go, but need help finding the proper kit since I don't have the stock springs. I'm having trouble contacting Air Lift, so hoping someone here has experience with them. Should this work? Thinking of having them shipped to my next destination and either trying to install them myself or finding a shop to do it.

edit to add that I didn't have the squat problem with stock suspension and SumoSprings.

 

So I use those to help with my trailer and lifted jeep....not cuz I care about a squatty look, but I do care very much about blinding people with my headlights at night, and it doesn't take much weight in the rear to push those lights too high up front. Unfortunately, I'm not going to be a ton of help in picking the exact ones for your specific application. I'd suggest you measure the distance in your spring from axle to frame and double-check vs. their application guide. I do recall it being very confusing if their measurements included the pucks or not.....and tbh I really don't recall. I gambled on an open box item from Amazon for half price and they were a little undersized, but still do the trick well enough for my application when driving at night. I would suggest you error on the side of the bags being too tall rather than not tall enough. Do you have onboard air? That sure comes in handy. I find mine do lose pressure overnight, especially with temperature changes.

In regard to installing, I wouldn't waste your time trying to shove them between your spring coils like you'll see videos doing. That is a joke if you have aftermarket springs, though I do have 3.5" coils. It is likely you'll have to remove the coil to get the bag up and in there.

As far as "fixing" your issue....that they will do. They obviously will make the ride a bit rougher as the suspension will be pretty stiff in back.

 

@resharp001 Thanks for the reply. I just sent Air Lift an email with a rough measurement of the springs and a link to them at TeraFlex. My concern is also about headlights. Along with that, I want my trailer to ride level for safety reasons. I don't have onboard air, but do carry a portable compressor with me. Not as convenient, but it should work out. I am leaning toward finding a shop to do the install. I'm old and crawling under the Jeep and fighting with the springs is something I'd like to avoid. From watching the install videos, it looks like having the vehicle up on a lift would really help. Thanks again.

 

Y, those bags are not near as flexible as you'd think either. I watched a couple videos where the installer scrunched em up and got them through between the coils. That method is 100% a waste of time in my opinion, so likely better to have a shop pop em in for you then. With a lift a shop should be able to unbolt the rear TB at the axle and simply lift the jeep high enough (drooping the axle) to easily remove the springs, insert the bags, and get the springs back in. I'd guess that install should be under an hour IMO.

The portable compressor will be fine, as long as you have something with you. When I get someplace and disconnect the trailer I just let the air out of the bags cuz it makes the rear end so stiff and jarring if you don't and I'd prefer not to drive around trailer-less at my destination with that harsh ride.

 

Another option may be the Timbren SES. Timbren SES JRJK - 2008 to 2021 Jeep Wrangler JK, JL Rear Suspension Upgrade. I had a similar setup on an older dodge truck i had and it worked really well. They're sort of a progressive bumpstop. plus they dont require airlines, compressor, etc. Just another option.

 

Alternatively you could put an equalizer hitch on as that transfers the load towards the front of the Jeep and rearwards on the trailer. Makes them a dream to drive with and will get rid of most of the sag. They have the 2 torsion bars beside the hitch and you use the trailer jack to raise to required level then hook up chains. Then remove when you get there. And the other benefit is almost zero trailer sway.

 

Gosh, that sounds a lot better of a solution. I've always seen things like that as "anti-sway" but never really looked at how they re-distribute the weight.

 

@Sixty4x4 & @resharp001 The weight distribution hitch is a great solution. The problem is that my trailer has a light weight frame and the manufacture specificity recommends against them. I haven't heard back from Air Lift yet. Maybe Monday. Really hoping the version that fits the stock suspension works with my small TeraFlex lift. Probably not that important, but I like the idea of being able to scale back the pressure when not towing.

 

If your trailer is a lightweight frame then how much offroading punishment will it see? Does not look like a boulder crawling rig so suspect it will be treated easy.

 

@Sixty4x4 You're right. Beside the stress from towing, my Wrangler is treated pretty easy. I do get off road, but no boulder crawling. The trailer doesn't have a lot of ground clearance. Mostly exploring easy double track trails after unhitching. Got to be able to get the trailer (and my wife) back home again.
