I've had F150s for the last 15 or so years. I bought a 2022 Laramie with the 3.92 rear. I was surprised at the amount of sag when hitches to my TT. It's a TT with a dry weight around 5400lbs. The power is great, it'll move, my question is; is significant sag anticipated? I heard rams sag a lot, it does more then my Ford did, but the Ford had a smaller rear. I've heard from 2 different people, one says it looks fine, the other said helper springs are needed. Just looking for advice from other ram owners with more experience with them. Thank you
I put some airbags that fit inside my coil springs with about 20 pounds of air in the bags. Solved the problem

Going to go with the check bars and readjust set-up crowd here. Hundreds of tows with multiple rigs over the years and have never had a sag problem when there is a proper set-up and not over on weight. Never needed the expense or potential problems of bags, which only mask a problem and don't fix it.

Find a reputable hitch company, even if you have to drive some, and have them check out everything (truck, trailer and hitch system). You may need some new bars and other tweaks to the hitch set up to get it right. Good luck.

2019 Ram 5.7 4X4 3.92. Totally Stock. Properly set up WDH. Trailer as sitting is 7700 lbs at Cat Scale. You have something wrong. A picture is worth a thousand words sometimes. Totally level.Level Truck and Trailer.jpg

Go get you a air bag set up, I had gotten mine from sdtruck springs https://www.sdtrucksprings.com/inde...fBC2vPN2KuHm9joHRBSvRQ4DGFjnYtkxoCvZsQAvD_BwE

here is the pump with the fob. This will improve your ride while towing and will eliminate your sag issues

Another thought, check your tongue weight of trailer. I see the volume of stuff that comes out of trailers in campgrounds and it is often like watching a clown car at the circus. You could be unbalanced with payload in trailer or just plain over. Been said before, get everything you travel with in truck and trailer and then do full rig weight, then truck weight, then trailer weight, and finally the tongue weight numbers. Fixing sag always needs to start with knowing what is causing it and getting under max numbers and properly balanced. Don't throw money at it until you know your numbers. There is the possibility the fix is free, just remove and/or distribute weight. And because it has to said, don't just move weight over/behind trailer axles without knowing numbers. You could end up waggling yourself into incoming traffic or a ditch.

Did you re adjust your WDH going from the Ford to the Ram? If not, you probably need to do that first. That may take out the sag without any modification to the suspension.
Listen to what ****** said above. He nailed it. I tow a similar sized trailer with very little sag.

I installed the bags that fit inside the coils on one truck (two trucks ago). They worked good but only lasted 3 yrs.

On my next truck I installed air bags but didn’t like how much they stiffened the ride.

On my current truck, I just cranked up the load on the WDH. If I have a bunch of stuff in the box while towing I live with a bit of sag (not as much as in your pic). The 5th gen ride so nice that I didn’t want to mess with it for the occasional time that I tow.

You don't need airbags or helper springs, you need to adjust your WDH properly or maybe get a better one. I tow 6400 lbs. with my 1500 and it sits level. You should also get on CAT scales and see how much weight is on each axle; I almost guarantee that you are over the limit on your rear axle (see door jamb sticker).

Just something to check that happened to me, one of the bolts on upper control broke on my 2015 ecodiesel and it looked just like that, once i replaced both with core 4x4's it's was fixed.

What weight distribution kit do you have? What are the bars rated for? If everything falls within spec you might need more torsion on them. Do you have sway?

Got one. Forgot to mention that
First off, the picture you posted, with the orientation of the truck and trailer on the grass/payment falsely amplifies the sag.

A properly adjust weight distribution hitch will transfer hitch weight to the front axle thus relieving the rear sag.

Okay, I know this is going to raise some hackles. But every time I read 'Airbags or springs etc to fix rear sag" I groan.
Humor me people and check these couple of tidbits from the interweb. :cool:

1. Do airbags replace weight distribution hitch?

No. WD hitches actually lift weight off of the rear axle to transfer it to the front axle and trailer axles. Airbags leave all of that weight on the rear axle, and just push the rear of the tow vehicle up.Jan 1, 2019

2. Do you need weight distribution hitch with air suspension?
Airbags cannot distribute the weight from the rear axle, so a weight distribution hitch is recommended for a safer journey, even with an airbag system.

3. Like an airbag, a WDH will raise back of the tow vehicle, reducing some of the sag caused by the trailer's tongue weight. But the way a WDH raises the rear of the truck is key – it uses torsion to shift a percentage of the tongue weight to the front axle of the tow vehicle.

Also. This design shifts 20%-30% of the tongue weight back onto the trailer tongue, which transfers it back onto the trailer's axle. This setup helps create more even weight distribution throughout the entire setup.

And finally, 13 minutes of your time may keep you from Flaming me :33:


Have fun.

Roger that! Thank you sir!
Totally agree. One thing to add though is lets not be too quick to bad mouth the trailer dealers and their set up as some here like to do. When I was picking up my new Travel Trailer, I'm sure the dealership did the best they could given that they had no clue how much weight I would load in the trailer, in the back of my truck, and where in the trailer the weight would be loaded. The guy at the dealership had the empty trailer plus two batteries and two full propane tanks, but the rest was up to me. I would have been very surprised if I didn't need to make some adjustments after loading up. That's why using a scale is so important.
