I bought an awesome M116A3 military trailer to tow behind my Jeep but the suspension sags in the rear due to the weight of the surge brakes on the trailer. My dad surprised me by ordering Firestone air bags helpers for the rear. Has anyone used them before? What am I supposed to do when I go offroading, just air them way down? I'm just concerned about losing all my articulation. Thanks.

Oh, and pics before anyone asks. I have a 4" ProComp lift and you can really see the sag in the rear:

First of all, good score on the trailer. Those things are awesome. And yes, on the trail you just let all the air out. I was thinking about getting these myself but didn't so let me know how they work for you when you get em on!!! good luck!

Have you done much offroading with them? How is your articulation?

I had them on my stock rear springs and I have a newer bigger set on my lift, they are awesome off-road, I don't air mine down, in fact you should keep a little air in there all the time so they don't get pinched. On my stock setup, I only had to use about 5-10 psi to keep the back end up even when I was pulling my pop-up trailer

Crap, I think the ones I have are for a stock suspension. Which bags did you buy for your lift? I have a 4" lift.

When I got my new ones I had to measure the inside ride height and width and then I called the company for a size, they told me I had the biggest size. I have 2.5 inch lift and they don't quote go all the way up or around, but they certainly help a lot, give a little support to the springs. I don't recall offhand the size.

Gotcha. Any reason you could not use a spring spacer underneath the airbags?

Don't know the answer to that one...
