When you’re towing a camper or hauling heavy gear, sag in the rear end can throw off handling and braking. The LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to keep your vehicle riding level and steady. By sharing weight across all four wheels, they help maintain steering control, braking performance, and proper headlight aim even under heavy loads.
Rough roads don’t have to mean a rough ride. Each LoadLifter 5000 Ultimate air spring has a closed-cell urethane jounce spring inside that absorbs bumps and helps prevent bottoming out. The jounce acts progressively—the more weight you carry, the stiffer it becomes—so your ride stays smooth when light and stable when loaded. If air pressure ever drops, the internal jounce still supports the suspension as a fail-safe backup.
Every trip is different, and this system adjusts to match. Each side can be tuned independently between 5 psi and 100 psi for front-to-back or side-to-side leveling. Inflate through the included manual valves mounted on the bumper or another accessible spot. Add pressure when towing or hauling, then drop it down for a softer ride when unloaded—it’s that straightforward.
These air springs are made with 2-ply, fabric-reinforced rubber for long life and consistent performance. Air Lift’s exclusive upper and lower roll plates protect each spring from moving parts while increasing load capacity. High-strength Zytel nylon endcaps are lighter, stronger, and more corrosion-resistant than steel, while the urethane jounces require no maintenance in hot or cold weather. It’s a durable setup made for years of real work on the road.
The LoadLifter 5000 Ultimate kit comes complete with mounting brackets, hardware, air lines, and inflation valves so you can install it yourself using standard tools. Just mount the springs, connect the lines, inflate, and go. If you want to add even more convenience later, it’s compatible with compressor systems that let you monitor and adjust air pressure from inside the cab (sold separately).

Ratings & Reviews
I purchased a set of these airbags for my old truck from etrailer and ran them for 17 years pulling a 42’ fifth wheel without any problems. So there was no hesitation for me to order the same for my new truck. I looked up everything I needed up on the etrailers site and called Josh at etrailer and he verified what I needed and got it on order. Also he verified my onboard compressor would work with the new air bags. Everything was received in a few days as usual. The airbags came with very good instructions and were no trouble to install and installation went quickly and have been preforming great. etrailer is always my go too for my truck and camper parts, also the bonus is if you have any problems or questions you can call etrailer and talk to a real person and get any problems corrected. etrailer for the win.
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.
Added this system to our food truck. It made a world of difference while driving. I support this product and have showed it to other food trucks by me.
Great product
I ORDERED SOME AIR RIDE SUSPENSION KITS FOR MY FOOD TRUCK. I HAVE NOT HAD A CHANCE TO HAVE THEM INSTALLED YET BUT I WOULD LIKE TO COMMENT ABOUT HOW FAST AND KNOWLEDGEABLE CRYSTAL WAS WHEN SHE WAS ASSISTING ME. A GREAT JOB GIRL!!!!!
Good product. A slight change from the Firestone double convoluted airbags that originally came with my Chevy p30 Itasca motorhome. But after a few hours of getting them into position properly, the ride is extra smooth. I run these at 100psi and they may only have a slow drop to 98 or 97 psi after a few days. Instructions for the 90 degree elbow say hand tight and then 1 and half more turns, but my passenger side bag, leaked immediately. Pulled the bag back out and reset the elbow with teflon tape and gave it a few more turns. Checked with soapy water, and everything worked perfectly. Depending on the position of your axle, you may have to set the bag a few times adjusting the mounting plate for best fit. The printed template unfortunately didn't help in this 3d space. Best to get as close to upright as you can when you find the correct mounting position.
etrailer was able to deliver these in 2-3 days and had them shipped the day of order.
