Rear End Sag

I was think the air bag that fit inside of the springs so I keep my Cadillac like ride for day to day driving and stop the sag on my camping trips

Inside the spring or outside doesn't change the function. With little or no air you are running on your stock springs. The bags only serve a purpose when aired up. The inside the spring ones are usually the "1000s" which I suppose means pounds they support. The ones I've run are the 5000s. So, 5000#? I suppose but that's far more weight than I'd ever need them to support. Anyway, they are too big to fit inside the springs so they are installed adjacent. The physics and idea is the same. I really like the airbags because they essentially disappear when not in use (although you should keep a few psi of air in them to keep them from folding and tearing).

Install a set of timber grove air bags, you won't be disappointed

I don't have air on board but ran the air to right under my bed lights. 7psi when unloaded, 40-50 when loaded with 10k lbs behind me

I installed the air lift 1000s and HD springs. World of difference but your ride will be quite a bit stiffer. I've had 3500lbs in the bed aired up the bags to take the saggy ass out. Went down the road like a champ. Rode like I had 1000lbs back there besides the extra throttle to go.

How does it ride when not loaded? Do you periodically check air pressure?

What was the cost of the timber groves.

What was the cost of the timber groves.

$368

Took me 2 hours to install with poor tools, a poor jack, and uncooperating weather

I noticed this on my 2017 1500 Laramie. I thought maybe a previous owner had exceed the payload enough or enough times that it did some permanent adjustment to the suspension. When my truck is parked in the right spot it almost looks like my rear bumper is lower than my front bumper. Can anyone tell me the best way to take measurements and see exactly where the truck bed sits and what the height SHOULD be? Am thinking that I definetely need some suspension work or heavier springs. I actually carry two dirt bike on a double motorcycle rack maybe once a month and the truck squats way way down. Truck is 4WD and the rack is made for two bikes so it should carry them. They do stick out of the back of the truck so the payload is way far back. But then I take the bikes off and my optical conclusion see's the bed of the truck angling down. Like it has been bent in the middle between the cab and the bed. I can take a measurement from the top of the bed to the ground, but what is that height supposed to be? Am I looking at worn leaf springs on a 2017 or taxed shocks or what should I be looking at or for? By the way I have a fiberglass top on the back of the truck. That is why the bikes are not carried in the bed.

Airlift 1000's!!!! Had them on all 3 of my 4th gen 1500's and they do a great job. Air em up when you have a load and then let the air out for normal everyday driving. Read about them and see if they'll do the job.

Do you have a picture to post the the problem you see between the cab and bed?
I don’t think there’s a measurement of what the rear SHOULD be.
You can compare yours to another truck to give you an idea. But keep in mind you already have the weight of the fiberglass need cover. 100+lbs I’m guessing?

No idea what kind of dirt bikes you have, but a 450 weighs about 220+lbs each. And with the carrier you’ve got 500lbs+ at the very back of the truck. That’s a decent amount of weight. I wouldn’t change your rear coil springs for new stock replacements or for aftermarket stiffer springs. You’ll still have a problem with the weight with new stock springs and the aftermarket stiffer springs I don’t think will help all that much. Plus your ride will suffer with the stiffer springs with no dirt bikes.
I would get some airbags to help when you have your dirt bikes. The airbags are inexpensive, easy to install, and you’ll able to keep your smooth ride you currently have. Just put a little air in them when you load up your bikes and your truck will sit level and they’ll help with the handling too, a bunch! New shocks will help control the bouncing you’ll get with the weight, but not a bunch. Air bags are the way to go!

Sorry I just noticed that someone had replied. Can someone tell me how/where to measure from to confirm this? It may be an optical conclusion but it looks like the point where the bed meets the cab is the pinnacle. Obviously not that dramatic but if you took a straight line from the hood back to the tailgate the point where the bed meets the bulkhead would be the high point. I just want to make sure I don't need new coils or springs. It really does it with the dual bike carrier on the back with a KX250 and KX450 on it. I know it is sticking way out past the bumper but the Lariat 150 4X4 I had previously did not look that way.

Thanks for the suggestions. I will install one of them. I was just wanting to know if there was a surefire way to know if the truck had an issue with being overloaded or some kind of damage before I start to try and chase something and counter a physical problem with the suspension or frame of the truck. Truck is awesome. First Dodge Ram I have ever owned. It just looks kind of "bent". I will get some more pictures.

You can use the Timbren SES kit as well. They work well for sag. Never need adjustment or air and 5 min install....I recently put them on my 2019.

Compared to a stock truck, looks like it’s your front end that is raised up. May want to check if the previous owner installed a leveling kit or something. Perhaps it can be lowered to adjust the rake.

Yeah, that looks like the front is lifted. Maybe it has coil spring spacers in the front. If it has those, I'd remove them.

Little more spendy, I took out rear coils and installed ridetech airbags with timbergrove autoleveling setup for the rear. Rides better than the coils and is always level no matter what you tow or haul.
