Firestone Air bag/Helper Springs (Rear Expedition sag)
Hello All,
I was wondering if you know of any companies that makes air bags for a 2005 4x4 Expedition? I ask because sometimes I tow my approx 6000 pound travel trailer with my expedition and even with my EQ/sway bars installed, I still get to much sag. Any one tow with their expeditions, if so what do you use to eliminate the sag?
Thank you so much

I had the same problem on my 99 expedition towing a 26 ft. jayco. I posted a similar question on the Towing forum at Woodalls. The basic response was to redo my setup by tilting the hitch head. My Dad and I spent a couple of hours doing this and now the back of my expy only sits 3/4 inch lower hitched when compared to unhitched. The front height is the same hitched or unhitched.
Look at the original post for more numbers before and after I redid my setup.

I tow a 24' 5500 lb TT and get very little sag from the air bags, see picture below.
My Reese hitch has the top of the trailer ball at approximately a 15 degree tilt toward the trailer.
The trailer tongue still moves freely and with the EQ torsion bars cinched up keeps everything pretty level.

Does your hitch head have teeth on the head and the washer that mate up to adjust the angle? My hitch head is the old style where the washers have two offcenter holes. The head is tilted at the maximum (not sure what angle this is) toward the trailer. Originally, the head was level and I was trying to reduce rear end sag by dropping fewer links in the chain. I read somewhere that it is recommended to drop at least 5 or 6 links. With my head tilted all the way, I can drop 5 links.

My hitch has a curved slot to adjust the angle, with a large bolt and two thick, square washers to secure it. It is in the most tilted forward position.
The height position bolt is in the third hole from the top of the hitch.
This is an old hitch, owned by my father-in-law for many years before I inherited it and the trailer.
I thought it looked odd when I got it but tried it before I adjusted anything.
Didn't need to do anything because it worked great as it is.
He always towed with a Ford F-250 2WD, so the setup worked well on my rig.
Can't remember how many links, but 5 or 6 seem about right.
