When the back end drops under a heavy trailer or bed load, your steering and braking can get sketchy fast. The LoadLifter 5000 air springs give up to 5,000 lbs of load-leveling support so your ride height stays where it should. That means no more rear sag, no more headlights pointing at the sky, and no more uneven tire wear. You keep control of your truck and your trailer tracks steady, even when you’re hauling serious weight.
Every load is different, and the LoadLifter 5000 lets you match your suspension to what you’re carrying. Add air for towing or loaded work days, then drop pressure back down for a smoother ride when empty. Each spring can be inflated independently for side-to-side leveling when things aren’t perfectly balanced. Manual inflation valves and air lines are included so you can fine-tune support exactly how you want it.
These springs aren’t built for show—they’re built to last. Each air bag uses 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion-resistant than steel. Exclusive upper and lower roll plates protect the bags from damage while increasing load capacity, keeping the system solid through years of towing, hauling, and rough roads.
Heavy loads don’t just sag your suspension—they make every bump feel worse. The LoadLifter 5000 absorbs road shock and cuts down sway so your ride stays stable and comfortable. With even load distribution across all four wheels, braking feels more controlled and steering stays predictable. You’ll notice less bounce, less porpoising, and a more planted feel on highways or uneven terrain.
Installing real load support shouldn’t mean tearing your truck apart. This kit comes with mounting brackets, hardware, manual valves, and air lines ready to bolt on. Just mount the springs, route the air lines to an easy-access spot on the bumper, inflate them, and hit the road. It’s a solid upgrade that fits right the first time without complicated modifications.

I load my F350 just under its legal limit of payload with my 5th wheel. I had initially relied on overload bump stops to prevent sag, but the ride was far too uncontrolled for my liking. I have used Airlift bags in the past on a previous vehicle and loved them. I bit the bullet and installed them on my F350 SRW and could not be happier with the ride quality and control they provide. Instead of bouncing and bucking us out of the seat while destroying steering authority on the HWY, now I have control of my payload and a stock ride when I am unloaded. I should have gone with the bags to start and I cannot recommend them enough for all the 5th wheelers out there or anyone else who tows heavily on a regular basis. The kit supplied everything needed, although I added a simple piece of bar stock to mount the schrader valves. Very clear instructions that were easy to follow.
I just completed the install of this Airlifter 5000 series air bag kit. First, the kit, without a doubt, is a high quality kit with many of it's components designed specifically for specific vehicle application. I installed it under the rear of our new-to-us 2021 Ram 1500 Crew Cab Laramie 4x4 Ecodiesel. I was very pleasantly surprised by the nice and robust powder coating of the metal mounting plates. That means protection for them for a long, long time. The hardware/fastners were/are of decent quality also. And, while the "springs" used for the temporary carriage bolt retention in part of the install are a good idea, I have maybe a better way of doing that. In my opinion, for whatever that's worth, here's a suggestion.
Since there are TWO of those carriage bolts that have to be installed AT ONE TIME, you now have to deal with those two long tailed springs, carriage bolts that continue to fall backwards into the abyss of the frame, all the while trying to maneuver the frame mount plate into position. Then, trying to retain tension on the tails of those springs that retain the carriage bolts, and align the bolt tips to enter the mount plate, and then, if and or when you get the mount plate into position and both bolt tips are protruding through it, you now have to hold ALL of that in place, while you remove at least one spring so that you can now grab a nut (a feat unto itself) and fit it onto the tip of one bolt, all the while trying to hold tension on that bolt so it won't fall backwards into the frame and start threading it.
Then, once it's threads are started, you can no concentrate on the same operation for the second bolt. What a serious pain in the petute!
But instead of the springs and tails to be used to retain the bolts while prepping to install the mount plate, you use whatever their called, a very, very thin retainer clip or washer or "push clip" (I really don't know the name of them) that are used to retain the drums onto hubs on an axle, ALL THOSE PROBLEMS would be over.
You'd simply use the springs as before to load and pull the bolts through their respective holes as before. Now, with the one bolt in place, reach through the center hole in the frame that's between the two bolt holes and using a finger, push on the head of that installed bolt. Your finger will now hold the bolt in place. Now, with that bolt held in place, you can remove the spring. Then, PUSH the very thing spring clip right over the threads of the bolt and it will "ratchet" down the threads until it bottoms out against the frame. You have now LOCKED that bolt in place and you can let got of it with your finger and that bolt isn't going anywhere!!!!!!!!
Now, do the same for the second bolt. Now, both bolts are held firm in place WITHOUT the long and cumbersome tails of the springs. You can now grab the mount plate and push it up into place and over both exposed sets of threads at the same time WITHOUT FEAR of pushing the bolts back into the frame. You can now hold that mount plate in place while you grab one nut at a time and thread it all the way on. Then do the same for the other nut.
To me, this would be waaaaaaaaaaaaaaaay easier than the method you (and I, and any installer, be it a shop or a home install) are presently using. If I had a link to what kind of clip I'm talking about, I'd link it.
But, those clips are seriously thin yet are quite capable of retaining those bolts and will not hinder the mate-up of the mount plate to the frame sides. Sure seems worth a looking into to me. Just a suggestion.

I didn’t do the install myself. However my mechanic talked me into these after adding a rack and rooftop tent to my ‘14 Tacoma. Absolutely Fantastic. I have a 3” suspension lift and the truck handles as near to stock as I can remember. Awesome product. Easy install (according to mechanic). Thanks all. Oh yes, one issue because I added a leaf spring when I lifted it. He had to find new shackles to allow for fit. FYI
Took my time and followed included instructions exactly. Went together well! Haven’t towed with them yet, but definitely raised the back of my Tacoma with 26 lbs of air pressure that I tested for leaks with! Feel like they’ll be a big improvement when towing our 4200 lbs. camper!
Watched the install video twice before the shipment got here and had no problems installing it. Also installed the WirelessOne from Airlift at the same time. Picked up some 1/4" clamps to make the air lines look a little cleaner, and hold them in place during our snowy and icy winters. Including the WirelessOne system, it took about 8 hours from the time I washed the underside of the truck until I rolled it back out from the garage. Pulled the camper this morning and all my old issues have disappeared. Truck is level, trailer pulls great, and the cooling system is back to working as needed. Highly recommend this suspension kit!
Makes for a better ride.thank you
Got it within days. Literally! Parts are all there and looks to be an easy install for me.
Service and videos are great, I have already recommended etrailer to friends after this purchase.
Ok when towing fifth wheel but emty ride is terrible whether you use 0 psi or 5 lbs. Psi
It's what I ordered and shipping was reasonable thank you
They work great. The install wasn't too bad. There are videos on Youtube that show the install without removing the back tires. It's easier if you take the tires off and have 2 floor jacks. It took about 30-40 minutes to do the driver's side and less than 10 for the passenger side (after the learning curve).
They were easy to install, and we can tell the difference. Very satisfied with the purchase. Thank you, Trailer.
The Airlift airbags I installed on my 2015 Ford F-150 were easy to install and everything fit as described.
I have made several purchases from etrailer.com and am very satisfied with the products they sell and the speed in delivery.
Airbags are easy to install maybe took myself 3 hours start to finish..
An I needed them to pull my 35’ bumper pull camper around from job to job with a 2015 f-150 xlt supercrew 5.0 v8.
So now I’m able to add 65 psi into each side an level out my truck.
Makes everything about it much safer.
Very happy with purchase.
Now if only I can purchase the onboard air compressor system I would be sitting pretty.
Highly recommended...

I have provided a link to our Air Lift compressor systems for your reference and you can an option based on your system needs. All of these compressor systems will accommodate 65 PSI with no problem.

So far so good.
Pretty straight forward installation. Good quality hardware and instructions are easy to follow. Installation is much easier if you remove the rear tires. Remove spare tire if routing the air lines to the rear bumper.
Do you have a question about this Vehicle Suspension?
Condition: Installed
Notes: There are install marks from previously being test fitted. All hardware is included.

One year later I still like these airbags.My truck rides level and handles smoothly. Without a load, however, its stiff in back and bounces, even with the airbags deflated.
