When your trailer or bed load gets heavy, the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers help your suspension stay level and under control. With up to 5,000 lbs of load-leveling capacity, they reduce rear-end sag and keep your steering, braking, and headlight aim consistent. The system shares the weight across all four wheels, easing the strain on your stock suspension so your truck feels steady even when fully loaded.
Roads can be rough, and loads can shift. Each air spring in this setup has a closed-cell urethane jounce inside that absorbs bumps and keeps you from bottoming out. These internal jounces engage progressively—the more weight you carry, the stiffer they get—so the ride stays stable without feeling harsh. They also act as a safety net if air pressure drops, temporarily supporting your suspension until you can make an adjustment.
No two loads are the same. With air pressure adjustable between 5 psi and 100 psi, you can fine-tune how firm or soft the rear suspension feels. Inflate both sides equally for front-to-back leveling or adjust them separately to even out an off-center load. Manual inflation valves and air lines are included, and a compressor system with in-cab gauges can be added later for on-the-fly control.
These LoadLifter 5000 Ultimate springs are made for real work. The 2-ply, fabric-reinforced rubber air springs are protected by Air Lift’s exclusive upper and lower roll plates that guard against damage and provide a larger rolling surface for better support at lower pressures. High-strength Zytel nylon endcaps are lighter and more corrosion resistant than steel, while urethane internal jounces require no maintenance and hold up in both hot and cold weather.
This kit includes the brackets, mounting hardware, air lines, and manual valves needed to install it yourself using hand tools. The no-drill design uses existing mounting points for a clean fit. Once installed, just pump in air through the valves—typically mounted on the bumper—and you’re ready to haul with a leveled stance and smoother ride.

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.
all good,already installed!!
Great product. Installed on a 2008 Ford F350. Made a huge difference with the ride when empty and towing/hauling.
They work great for leveling out my pick up with a heavy load
The kit was complete, instructions clear, and part quality high. It was a relatively easy install and the system has performed well.
I put a camper on my truck. The airlift works great. My truck is back to being level and oncoming drivers don't think i have i have my high beams on. Also when i'm pulling into campgrounds my springs don't squeak anymore. I was able to install myself with a few trips to the auto parts store for some longer bolts due the the 5th wheel Hitch on my truck.
I bought this setup for my 3/4 ton F-250 and 5th wheel. I was tired of oncoming traffic flashing their high beams at me when driving at night. This was due to the 5th wheel being heavy enough that when hooked up, the rear of the truck dropped about 2-3 inches and angled my headlights into the eyes of oncoming traffic.
After researching air bag/helper springs and compressors, I decided this was the system that would fit my needs. The Air lift Load lifter 5000 air springs along with the Air Lift Wireless One compressor were perfect to level the truck out when the 5th wheel is hooked up. This setup is great and gets the job done. I did measurements on the truck rear end before and after the 5th wheel was hooked up to determine ride height. This let me dial in the right pressure for the compressor and air springs to maintain and keep my rig leveled out. No more oncoming traffic flashing me because my headlights are in their eyes.
Installation was simple and the directions pretty clear. Since this isn't my daily driver, I took it slow and installed the air springs over a couple of evenings after work. I didn't like the idea of mounting the compressor under the truck on a frame rail, so I mounted it inside the bed on the driver side front corner with a protective cover. This way, it is also protected by my bed cover and if necessary easy to access if it needs attention.
I give the compressor and air springs system 5 stars. But, I do have a complaint. The compressor will not let you go below 5 lbs of air in the springs. This causes the rear end and subsequently the ride to become much stiffer if there isn't any weight in the bed of the truck. Not sure if that is the fault of the compressor or the air springs. To compensate for this, I usually have some weight in the bed to help even the ride out. If I had it to do over again, I would still go with this system.
I pull a 39 foot toy hauler 5 th wheeler and these air bags work great. No sagging suspension. I air them up to about 70-75 lbs and never have a level problem and it makes the ride a lot smoother
