Features to know about

Stay Level Under Heavy Loads: Up to 5,000 lbs of Rear Suspension Support

When you’re towing a trailer or hauling a heavy load, the last thing you want is rear-end sag or bottoming out. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to your rear axle. They reduce strain on your suspension, improve steering and braking response, and keep your truck level front to back for safer handling and proper headlight aim.

Smooth Out the Ride: Built-In Jounce Springs for Comfort and Control

Bumps, dips, and uneven roads don’t have to make your ride rough. Each air spring has an internal urethane jounce spring that absorbs road shock and helps prevent bottoming out at low air pressure. The jounce engages progressively—the more weight you load, the stiffer it gets—so you get a stable, comfortable ride whether you’re cruising empty or loaded down.

Fine-Tune Your Ride Height: Adjustable Air Pressure from 5 to 100 psi

Adjust your setup for the job at hand. These air springs let you dial in air pressure anywhere between 5 psi and 100 psi for precise support. Inflate both sides equally to level front to back or adjust them independently for side-to-side leveling when loads aren’t centered. Manual inflation valves and air lines are included so you can mount them where access is easy, like on the bumper.

Built Strong to Last: Corrosion-Resistant Materials and Reinforced Design

Durability matters when you rely on your suspension day after day. Each LoadLifter 5000 Ultimate features 2-ply, fabric-reinforced rubber air springs protected by Air Lift’s exclusive upper and lower roll plates. The endcaps are made from high-strength Zytel nylon that’s lighter, stronger, and more corrosion resistant than steel. These materials protect against wear and tear while extending the life of your suspension system.

Straightforward Installation: Everything You Need in One Kit

Getting extra suspension support shouldn’t require a shop visit. This system includes mounting brackets, hardware, air lines, and manual inflation valves—everything needed for installation with basic tools. Once mounted, just inflate the springs to your desired pressure and hit the road knowing your truck is ready for whatever you load up next.

Video Transcript for Air Lift LoadLifter 5000 Ultimate Rear Air Helper Springs with Internal Jounce Bumpers Review

Instructor Today we're gonna be taking a look at Air Lifts line of LoadLifter 5,000 Ultimate Air Helper Springs with internal jounce bumpers. These bags are specifically designed for three quarter and one ton trucks and motor homes, you're big heavy dogs here. These bags are a custom fit for your particular truck so you want to use our fit guide to ensure you get the appropriate hardware and brackets to install them. To show off our airbags, we're going to add about a thousand pounds of water weight to the back of our truck. We're working with a Chevy Silverado 3,500 today, but the principles are the same regardless of your vehicle. Having your vehicle loaded down like this, bringing the back down and the front up, changes the geometry of your suspension, and it also changes the way weight is loaded onto your front brakes.

So this causes poor handling, as well as poor braking performance. By adding air bags into the back of our vehicle, we can raise the back of our vehicle back up, and that's also gonna help restore the suspension closer to that factory ride height as well. That's gonna give us better contact on the road with our tires so they don't wear excessively fast, it's gonna increase our handling because we're going to have better contact to the road, and with it level back up here at the front again, our weight's gonna properly transition onto the front brakes restoring a lot of that loss breaking performance. Another added benefit is by bringing the back of our vehicle back up, we're picking our headlights that we're pointed up towards the sky and bringing them back down on the road, so we we're able to see better at night as well. And here we can see our airbags installed.

They're going to sit between the axle and the frame of your vehicle, and they'll provide up to 5,000 pounds of leveling support. Now this doesn't increase the amount of weight that you can carry with your vehicle, that's just how much these can help to support and lift your vehicle back up to restore that lost ride height that you had from being weighed down. Inside of our airbag here, there's a jounce bumper, and what that does for us is in the event that we've got it so loaded up and we hit a really big bump, and our axle moves up. If it we're to go up so far, it could contact the internal jounce bumper and that's going to prevent any metal on metal contact, And it's also going to save our bag from any potential damage. This is mostly for when you get really heavily loaded, really pushing it, getting close to the maximum load limit of your vehicle, that jounce bumper can really come in handy when you're maybe doing some good speeds and you hit a pretty big pothole or something like that, that could save you and your vehicle from any issues.

To further increase the structural integrity of our bag, there's roll plates on the top and bottom, so as our vehicle goes to sway to the left or to the right, when we're making invasive maneuvers or just regular turns, the bag as it wants to lean to one side of the other, from that sway can contact on the roll plate here, and that'll provide it with additional support to ensure that our bags stay in place doing their job. The double convoluted design will help increase the structural integrity of our bag. It gives it a higher burst pressure by displacing the air as necessary as it moves up and down. And to further ensure the durability of our gags, they're constructed of a two ply fabric reinforced rubber, and they're very durable here. They have a increased size on that internal jounce bumper as well.

The urethane bumper is a little bit taller so it'll contact a little bit sooner, and that's really nice if you maybe haven't adjusted your air pressure quite yet, either. Maybe you've loaded it up and it's still a little bit lower pressure, that jounce bumper is always gonna be in there to provide contact, and then if you find that, hey, you're hitting that jounce bumper, it's a little stiff, you can up the air pressure a little bit to help bring that away and get the best ride quality, as well as the best support. You also receive a heat shield in your kit, this is gonna further protect your bag from any excessively hot sources, such as your exhaust here. You'll receive clamps with it and everything, so that makes it nice and easy to get that installed, and it's very easy to position it and however you need to for your particular exhaust system. So it's nice, even if you upgrade your exhaust system, you'll still be able to use something like this. Included with your kit, you're gonna receive airlines and all the hardware you need to get it installed. You'll receive two air fittings so that way you can inflate each bag independently from one another. This is nice if you're trying to correct any uneven loads, but really in most cases, when you're loading down your truck, you typically want to load both of your bags the same to just bring that support back up and level your truck back out, and in those instances, the easiest way to do it will be to install a compressor on your vehicle. On this vehicle, we've installed Air Lift's WirelessONE compressor, and this is one of the easiest compressors to install. It's completely wireless and you can operate it with your phone, so you don't have to worry about losing any kind of device when you're trying to inflate it. And you don't even have to get out of your truck to inflate it. So you could pull up to a place and have somebody drop a pallet in the back of your truck, adjust the pressure on your phone and take off. The operating range of our bags is between five and a hundred PSI. Five pounds is when we're just normal driving around, completely unloaded. It is important to have five pounds in there because as your suspension moves up and down, it can create a small vacuum in there if you don't have any pressure, so we just keep that five pounds in there. And then for your heaviest loads, we can go up to all the way to a hundred pounds to provide that support. Just wanna keep in mind that up at those higher pressures it does get pretty stiff, and in most cases, about 40 to 50 pounds is gonna probably be sufficient. And that completes our look at Air Lift's line of their LoadLifter 5,000 Ultimate Air Helper Springs with internal jounce bumpers..

I pull a 38 foot long camper with my Excursion. Lots of bounce and roll with a tongue weight of almost 1500lbs. After installing these air bags it locked in the rear axle and made the Excursion ride like it was a dually. No roll or sway and almost no more bounce.
Installation was straight forward and took me about 4 hours to do in the driveway with no specialized tools.

I'll have a better idea once they're installed in week or so but so far so good. Did a lot of research and Will at E Trailer was a great help making sure I was getting the right stuff for my Excursion.

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.

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.

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

Product works great and helps level the truck during towing. I have noticed a difference in the amount of travel my back wheels have when offloading. But I knew that would be a sacrifice.

Great instructions and easy installation! Fit perfectly! Loaded my tractor to test them out and they completely leveled my sagging truck with 42psi.

Happy to hear these are getting the job done! Your set up looks great, and man! What a beautiful picture. Blue, sunny skies, green grass, a cool breeze (I'd wager) perfect day to hitch up the trailer and get some work done!

Been great! I really don’t like the internal jounce stops though. When you are unloaded and running lower bag pressure, a dip or bump will hit the bump stops really hard and jar your passengers in the backseat. It’s almost too uncomfortable to ride in the backseat now. As for the loaded and high pressure performance it’s great! Great handling and no sag at all when towing.

by:
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.

That is great to hear, even with some modifications I am glad this is what you were wanting. That truck bed camper set up looks awesome. Do you have any big trips planned this year?

by:
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.
by:
I did the installation myself with auto ramps and a bottle jack. The instructions were good, however, some of the pictures were dark and hard to see. At 60 PSI and no load the truck rides like it has no shocks so I have been running 10 PSI and it seems to be great. 2015 F250 4x2 ext cab. I drilled the TAG screws and install the air fill ports in there place.

Incredible difference! Even with a weight distribution hitch i couldn’t get my toyhauler and tundra level. The internal jounce alone raised my hitch several inches but with air, Wow! Also note, you CAN keep the RAS helper springs installed. You just have to pry a little when installing the U-bolts.

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.

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.

@BrookeM I used the brackets from my timberon shock springs and modified them to support the 5000. This gave me the proper height, spacing & room that I needed. I then reinstalled the Timberons where my old air springs had been installed. Smooth ride now.

Overall I am very pleased with the LoadLifter 5000. I purchased for a 2017 Tundra 1794 which we pull a 26' travel trailer. Prior to purchase the truck & trailer had a noticeable sag and it was challenging to distribute the weight in the trailer to reduce the sag. With the LL5000 the sag is eliminated with around 40 psi and the overall feel of the truck & trailer was much more solid and less bouncy when going over rough roads. Also, I was able to haul some lumber several times were the load was around 1,700 lbs which was 600 lbs over the stock capacity of the Tundra of 1,100 lbs...this was done with 60 psi. The LL5000 really showed their performance there with no sag with this load. The only reason I give a 4 out of 5 stars is the drive performance when not carrying a load or towing the trailer. Unfortunately the drive is not as smooth as the stock configuration. I've tried adjusting the pressure from 0 psi thru 30 psi in intervals of 5 psi and unfortunately there's some added bumpiness no matter which psi is selected. Overall, at around 10psi that seems to be the best ride but again, not the smoothness of the stock configuration. But if you're needing to eliminate sag with a trailer or boost your haul capacity, the LL5000 will definitely satisfy those needs.

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.

@GwendolynY The trailer was picked up in a pasture and dropped off in another. Both the fetching and delivering were compliant rides. The airbags sure looked small during the install, but they managed my truck and trailer weight with ease and grace. It’s exactly what I hoped for when I purchased this air bag kit. The factory suspension was able to manage the bumps all while NOT having to fumble with the added cargo I pack around. I give this setup an A+ after driving it for a few days. The highway miles are on par with my truck brand new and empty. I’m very pleased with the product on and off road. I’ve dropped the pressure in the bags to 35 for a comparison, but I know there’s a sweet spot at 40 psi for my working conditions.

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

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.

These bags have been great! I installed them, along with the compressor, on my 2024 Tundra. I pull a 6k lb camper and was getting about 3” of squat. I run 45 lbs in them and it reduced the squat to only about 1”. Great price to fix my problem.

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.

Easy install thanks to a Great Video & decent paper instructions. I installed them using a single line for air compression. Extremely pleased with the performance & quality. Will be ordering the "Wireless One" onboard compressor shortly to complete the project! Great job, folks!!

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.
