When you’re towing a heavy trailer or hauling a full bed, rear-end sag can throw off your handling and headlight aim. The LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to keep your ride level front to back and side to side. By sharing the weight across all four wheels, they reduce stress on your brakes, tires, and factory suspension, giving you steadier steering and braking when the load gets serious.
The built-in urethane jounce springs inside each air spring smooth out bumps and protect against bottoming out. They engage progressively—the more weight you carry, the stiffer they become—so the ride stays steady without harshness. If air pressure runs low, the jounces act as a backup to temporarily support your suspension until you can adjust or repair it.
Every trip is different, and these springs let you dial in the perfect setup. Adjust air pressure anywhere between 5 psi and 100 psi to match your load—add air for towing or drop pressure when running empty for a softer feel. Manual inflation valves and air lines are included, and a compressor system with in-cab gauges can be added if you want to control pressure on the fly.
Each LoadLifter 5000 Ultimate air spring is made from 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that are lighter and more corrosion resistant than steel. Air Lift’s roll plates protect the springs from damage while increasing load capacity, and the urethane internal jounces require no maintenance. These details add up to a suspension upgrade built to handle years of towing and hauling without leaks or failures.
Installing the system is straightforward with the included brackets, hardware, air lines, and manual inflation valves. Mount the springs, hook up the lines, inflate them through easy-access valves—then hit the road with confidence knowing you’ve added serious support in just an afternoon’s work.

Hello, everybody, this is Jeff at etrailer.com. Today we're gonna take a look Air Lift LoadLifter 5000 Ultimate Air Helper Springs with the internal jounce bumpers for your rear axle. Now, this is a custom-fit part. It is designed to fit the 2021 and newer Ford F-150 Raptor four-wheel drive trucks. And on a custom-fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year, model, vehicle, and it'll show if this will work for the application. Now, this hybrid spring system will combine the adjustability of these air springs with the reliability of the internal jounce style springs that are on the inside.
These air springs reduce the strain on your rear suspension, increase safety, and compensate for any uneven loads. They'll help let you level your vehicle front to back, help maintain safe headlighting, and they'll even adjust independently for side-to-side leveling of any off-center loads. They do improve steering and braking performance. I'm going to zoom in some on those springs. And as we mentioned, on the inside of these air springs, they have a jounce spring that helps improve ride comfort, reduce sway, and help with cornering.
Those jounce springs will engage at lower air pressure to better absorb road shock and minimize bottoming out. And they provide support progressively, which means the more you load the springs, the stiffer they'll become. They'll even let you temporarily carry a load with zero air pressure in these air springs. And the urethane internal jounce requires no maintenance and works well in hot or cold temperature. Now, the air spring cradles right down here, this will let your suspension travel fully without compromising your ride.
Basically right now, you see the air spring will sit in the cradle when it's in use, and then it lifts outta the cradle so the suspension can cycle completely. And then it'll sit back in the cradle when the cycle is complete. Also, what's nice, remove this, and if you look at the bottom, you can see there's drain holes in those cradles. This will clear any water or debris from building up. Now, these are quality construction for a nice, long-lasting spring life.
They are springs that are two-ply, fabric-reinforced rubber air spring, which is durable. They have an adjustable air pressure of five psi to 100 psi. And the end caps on 'em are high-strength Zytel nylon end caps, which make 'em lighter, stronger, and more corrosion-resistant than steel. Now, these are designed for heavy-duty applications, such as 1/2-ton, 3/4-ton, and even one-ton trucks, motor homes, and commercial trucks. As you can see laid out here, everything is included. Mounting brackets, the hardware are all included for installation. Over here they have the manual inflation valves, and the air lines are all included. And these manual valves are typically mounted on your bumper for easy access. We do also offer a compressor system with end cap gauges that can be added to monitor and automatically adjust your air pressure. Those items we do sell separately on our website. These parts are made in the USA. A few specs, again, the load leveling capacity is up to 5,000 pounds. One thing I do wanna mention is that the LoadLifter 5000 Ultimate Springs will not increase your vehicle's weight-carrying capacity. So you do wanna make sure not to exceed the manufacturer's recommended weight limit. But that's gonna do it for a look at the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with the internal jounce bumpers.

Ratings & Reviews
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.
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 installed these on my Tundra and did the install myself. Easy to install. The video's on the website are helpful as well as searching on youtube for more videos. I use these for towing our travel trailer. They work great for inflating and leveling the truck and trailer. I would buy again if my next truck did not have them installed.
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.
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.
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.
I run an arctic fox 811 on a f350 single wheel, and these have been a game changer, no issues and helps that ride quality with the weight of the truck bed camper in the back. Having the air chucks in the fuel door is a recommendation I would recommend to anyone going without a on board air compressor
VERY GOOD FIRST IMPRESSION!
I have a 2020 Sierra 1500 AT4. I have the back loaded with a DECKED drawer system full of tools, plus all my gear in tubs for investigating fire scenes. My amazing pickup was nearly riding the bump stops all day. On a bumpy road, it was pretty taxing. Off-road was brutal. After some research I found this kit to fit my AT4 truck, part #88388.
You will need tall jack stands for this project. We ended up bracing ours on the rear leaf spring perches due to exhaust routing.
This is a brand new install, so time will tell as to how it holds up, but I have high expectations. This kit comes with paper instructions that are pretty spot-on. The pictures were helpful, and the instructions are detailed enough for a novice to understand. With one extra set of hands, I installed this kit in about 2 hours. I mounted the single fill valve in my gas-fill area, hidden behind the fuel lid. No bending over to add or release pressure.
After the install, I ran the pressure up to 40 psi as recommended. I got about 2 1/2” of lift out of that. I pulled a trailer home from the shop, and my truck rode like brand new. For my daily cargo, I think 40 pounds is just about perfect. And my tailgate is back at belly button height again. My headlights are shining where they should be shining. My bottomed-out ride is now compliant and comfortable.
The parts seem to be quality, and I had zero fitment issues. The only specialty tool was the T40 TORX tip for removing brackets from the axle front. You need it before you start. This kit is an easy install with a basic 3/8” socket set, a couple box end wrenches, and a couple other basic hand tools. This project should not scare too many people away.
Pro tip: You may think you can do it without taking off the tires. DON’T!! You’ll be pissed off at your truck and anyone nearby. The time savings will be worth it.
Also, the parking brake is on the back axle. Chock the front tires and/or put your rig in 4 low before lifting the back end.
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.
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.
Excellent product. I had the old version on an old truck and had issues- especially not having the jounce bumper. This new one has been excellent. Only thing I'd change is... spend a little extra and get the pump and wireless control... that my next upgrade. It's easy enough to adjust these with my cordless inflator...but that extra little bit will really make it a 5 start setup. 2020 Tundra TRD sport, tracrac, 4' tool boxes, access tonneau and bedside 1500. truck sagged without the airbags.
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
Great instructions and easy installation! Fit perfectly! Loaded my tractor to test them out and they completely leveled my sagging truck with 42psi.
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.
Great products, fast and easy shippig!
Man! This was super easy! Yes it took time ( 3 hours for me) but the complexity of the process was made simple with the instructions and video.
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!
