What exactly is this set up?

Crawling around underneath looking at suspension parts since I have the so called Death Wobble and seen this set up in the rear. Can someone explain to me? Looks like some kind of bags or bumpers? Maybe additional weight set-up? So many things on the truck are way different then my previous 2002. Thanks for all your help

Looks like you have air bags. Is there an air line going to them?

Not sure I will look closer.... I do hear what sounds like air compressor or fuel pump running for a short time after I park the truck. The previous owner towed a 5th wheel RV. I am wondering if I really need them or if they actually work right. Does this increase the harshness of the ride? I don’t see anything in the truck to control them

The sound you hear after you park your truck and shut it off is most likely the DEF pump pumping the DEF out of the dosing line/tube.

Yep there are air lines.... so if I leave no air in them then the ride will be normal? Is this a Ford option? I wonder why the would have had these..... It has the #10,000 GVWR package already. If I run air I have no idea who mage them of what pressures there should be in them

from past experience, I always kept a few pounds 10-15 in them to keep them inflated when not towing or hauling; I ran mine completely empty and it ruined the bags.

I used to run mine between 50-70LBs depending on what I was hauling and where the truck would sit. If you aren't hauling anything heavy, you can remove them and just sell them too.

Thanks nd4speed. I will leave them and make sure there is some plow pressure air in them is they even work now. If not I might remove them but if I can keep them in and functional that might be better for the future. i will bust out an air gauge and see what is in them and lower it and check the ride

You guys are great! I have so many questions with this newer style truck as I find little things that are different or not working right

Those are not a Ford option.

I cant see who the manufacturer is but the look like air lift so I looked it up and it says run a min of 5psi. They had 0psi so I put 5 in and will see if they hold. If not I am removing them and all the brackets. Are these normal for peeps running 5th wheels on std bed trucks with a #10,000 rating?
