When you’re hauling a full trailer or heavy gear in the bed, the rear suspension can sag and throw off your steering and braking. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to keep your ride level front to back. With support spread evenly across all four wheels, braking feels stable, tires wear evenly, and headlight aim stays right where it should.
Bumps and dips don’t have to mean bottoming out. Each LoadLifter 5000 Ultimate air spring has a closed-cell urethane jounce spring inside that cushions impacts and takes up slack when air pressure isn’t enough to handle the load. These internal jounces engage progressively—the more weight you carry, the stiffer they get—so the ride stays smooth without harsh jolts or bounce. Even if an air line leaks, the jounce springs act as a backup so you can still carry a load temporarily until pressure is restored.
Every trip is different, but dialing in the right balance is easy. The system lets you adjust air pressure between 5 psi and 100 psi to match what you’re carrying. Run higher pressures for towing stability or lower for daily driving comfort. The kit includes manual inflation valves and air lines that can be mounted on the bumper for quick access. If you want automatic control, it’s also ready for an optional compressor system with in-cab gauges (sold separately).
This setup is made to handle real work for the long haul. The 2-ply, fabric-reinforced rubber air springs are backed by high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion resistant than steel. Air Lift’s exclusive upper and lower roll plates shield the bags from damage and boost load capacity by spreading out pressure evenly. Quality construction from top to bottom means fewer worries about leaks or wear and a lifetime warranty to back it up.
Installing this system doesn’t require a shop full of tools. The LoadLifter 5000 Ultimate comes with mounting brackets, hardware, manual valves, and lines—all ready to bolt up cleanly over your rear axle. Just mount the springs, run your airlines, inflate them through the valves, and go. Once installed, you’ve got heavy-duty support on demand without changing your truck’s everyday comfort.

Ratings & Reviews
just installed loadlifter 5000 in driveway was easy enough with help of video and instructions. Only drawback was losing a clip inside the truck frame. Maybe including some extra hardware would be nice for us non mechanics. Would have given 5 star but have not hooked my trailer up to truck yet
I'm really happy with my purchase and am glad I purchased it here. Customer care was knowledgable, helpful, quick and friendly. Shipping was super fast. I couldn't be happier!
Some quick feedback that we have had the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers - Rear Axle kit installed on our 2024 Ford F250 Super Duty pick up a few weeks ago. Everything went well with the install by Valley Truck & Trailer in Castro Valley, CA. The team there did a great job at a fair and agreed upon price up front. Final cost was exactly as quoted. Not able to test out the air helper springs under load until we hitched up our fifth wheel. Over the past week we hooked up for a quick trip and WOW what a difference! We are very happy with the ease and speed to "pump up" to desired 60 psi with only a hand "bicycle" pump. The picture attached shows a before and after shot of our rig with and without the air helper springs installed. The difference is night and day. Most importantly I feel much safer and more stable and in control on the road with the truck being level vs. having front end higher than back end. I tried to add a review online at etrailer.com but the fields were locked and I was not able to add any pictures.
I don't usually go so far out of my way to review a product but in this case it is fully warranted. Thanks so much.
These airbags definitely give me a much better ride due to Toyota using coil springs in the rear. I would have given them 5 starts but one of the airbags inset thread was damaged and I was lucky enough to have the right tap. It wasn't noticed till I had my truck on the lift and the first bag installed. If i wasn't able to do that I would have had to uninstall the first bag and wait for a replacement. I understand these things happen but check your parts thoroughly before installing. I would purchase these bags again if needed.
This product was fairly easy to install. The biggest problem I faced was a suspension bracket on my passenger side next to wear I installed that airbag. It was not mentioned in the video instructions. I really struggled getting my tools and hands on such a tight spot. After an hour, everything was ready to roll.
Installed on a 2024 GMC Sierra Crew SLT with rear poly mono springs. This worked great and the install was easy. It took me about 2.5 hours on a 4 post lift, but you could do it in the driveway if you needed to. I reached out to airlift to make sure it would work on a vehicle with mono-springs and they were not 100 percent sure if it would. So I took a chance and it worked flawlessly!
2021 Ram 2500 install was easy, it took a while to run the airlines. I pull a 5th wheel camper 700 miles each trip, the air bags eliminated the side by side roll and keeps the bed level. So far I am very satisfied with the results. When I am not pulling a trailer I lower the air bags to 10lbs for a better ride.
I explained the size/weight of the load I carry in my duallie. A 5000lb slide in camper and a 28' twin engine jet boat. These bags are probably great for their respective load, but I was convinced by the sales team at etrailer that these would be sufficient. They aren't. I can put 100lbs of air (the max) in and truck still sags. Should have gone with the 7500 lb bags.
works very well. i installed them on a 2012 Ford F-150 towing a Grand Design 2600 RB. the airbags substantially helped cut down the bouncing when going over big bumps, bridge decks, etc. also helps with the side winds. very happy with set up.
etrailer delivered these in four days which was a pleasant surprise. The Load Lifter 5000 were easy to install and all of the parts fit perfectly. The installation instructions were spot on as well. I tried to save a little time by leaving the wheels mounted, that turned out to be a mistake, so I removed the wheels mounted on the second side and saved about 45 minutes. The loadlifters perform exactly how I want. They took all of the sway out of my tundra while hauling my truck camper.
Deliver was awesome, installation was a little more complicated than expected but had installed big wig sway bar and torklift lower wedges added some unexpected fitment modifications but I can say has delivered results I wanted.
The truck rides much better now, though I haven’t yet towed with the air bags yet. The bags took out that annoying side to side movement.
Just great!
Easy to install.
The AirLift 5000 work great. The installation brackets didn't work for my Toyota RV & I had to fabricate the ones that'd mount to the frame. Otherwise, awesome improvement to the stability & ride.
Great instructions and easy installation! Fit perfectly! Loaded my tractor to test them out and they completely leveled my sagging truck with 42psi.
Good system seems to made very well. I also got the Airlift Compressor as well Would have done 5 stars but the quick mount doesn't fit a 2025 F250 frame. About an inch to small. DIRECTIONS are terrible, pictures are blurry. Had to you tube the install. for that much money a couple of more pages explaining better with clear pictures.
Works amazing. The install was a little more difficult than it appears… It actually took me and a couple other guys five hours to get it completely installed.
There was a lot of cutting/grinding metal to make pieces fit properly, and had to drop the axel completely… I think that’s only for my gen 2 raptor.
At the end of the day, though I’m very happy with the result
Just had them installed, I’ll be hauling a 9800lb travel trailer soon. That will be the real test!
Added 40lbs of air, they sit the rear of truck up nicely.
I was easy to install just a few hours. Everything in the kit fit well. It would be nice if an extension brackets were provided for the brake line/abs wire mounting bars would be included like the brake line adapters that’s provided in the kit is my only recommendation to make it top notch.
One year heavy use and going strong! I put these on my 2500 truck with flatbed and truck camper and drove about 15k miles this year, with many rough dirt roads and also snowy roads. The installation worked out for me but was tricky due to double set of leaf springs, it wouldn’t have worked without the flatbed because to get the right height I ended up drilling some of the holes into the flatbed frame instead of truck frame only. Drilling was very hard and used several expensive bits with lots of oil to make a mess.
