Features to know about

Stay Level and Confident Under Load: Up to 5,000 lbs of Rear Suspension Support

Heavy trailers and cargo can make your rear end sag, throwing off braking, steering, and headlight aim. The Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers add up to 5,000 lbs of load-leveling capacity to keep your setup level front to back. The hybrid air-and-jounce spring design reduces stress on your factory suspension while maintaining even weight distribution across all four wheels, so the truck stays steady and predictable under load.

Air Lift LoadLifter 5000 Ultimate air spring with protective roll plates on each end to prevent damage and increase durability under heavy loads.

Smooth Ride and Added Control: Built-In Urethane Jounce Springs

Rough roads don’t have to mean a harsh ride. Each air spring has a closed-cell urethane jounce inside that engages when air pressure isn’t enough to support the load. This extra buffer smooths out bumps, reduces sway, and helps with cornering without bottoming out. The jounces react progressively—the more weight you add, the stiffer they get—so the suspension feels stable without being jarring.

Adjust for Any Load: 5 psi to 100 psi of On-Demand Air Pressure

Every haul is different, and that’s where adjustability matters. These air springs can be set anywhere from 5 psi to 100 psi for precise tuning. Add air when towing to stay level or drop it down when running empty for a softer ride. Manual inflation valves and airline kits are included for simple setup, and the system works with optional onboard compressors if you want in-cab control later on.

Built Tough for Real-World Use: Reinforced Air Bags and Corrosion-Proof Components

Durability counts when you’re hauling heavy loads day after day. Each spring uses 2-ply, fabric-reinforced rubber with exclusive roll plates that protect against abrasion and increase capacity. The high-strength Zytel nylon end caps are lighter and more corrosion resistant than steel, keeping the system leak-free over the long haul. Urethane internal jounces need no maintenance and perform reliably in hot or cold weather, so you can count on consistent support wherever you go.

DIY Friendly Setup: Everything You Need in One Kit

Installing these springs is straightforward with the included mounting brackets, hardware, air lines, and valves. Just bolt them up, add air, and fine-tune your pressure to match the load. No complex mods required—just solid bolt-on support that keeps your suspension working smarter every trip.

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..

The air lift is of high quality. I was able to lift my 2023 Thor Sequence RV 2.5 inch with the air bags. I needed that to get over a hump in my drive way. I loved the fact I did not need any additional parts for installation. I would highly recommend this product. It will be very useful for leveling at camp sites you can level one side at a time.

It works great for lifting my RV over the drive way hump. I wish I had puchased the air lift load controller it would be less work than using a manual pump. It looses air over time so leveling for camping you have to refill the air bags manualy every day. I do not drive with them inflated because it does not change the suspension dynamics. It only lifts the rear end.

Easy installation with excellent directions. Works great on my 2022 Thor Sequence(RAM Promaster 3500 chassis). Running 75 psi, great stability and improved ground clearance. Generator hung 1” below rear axle, now 1 1/2” above with more available. Love it!

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.

by:
2024 GMC Sierra 1500
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.

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.

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.

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.

That’s a pretty clever spot for the air fittings, I’m definitely taking note for the future! Also, if you ever run into instructions where the images are hard to see, feel free to reach out. We’re happy to email you a clearer digital copy anytime!

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.

  • Lift Kit/Suspension Leveling Option For 2023 Ram ProMaster 3500
    Hey Bill, thanks for reaching out! We have suspension enhancement kits that work in tandem with an OEM suspension, but none of our kits are actually for lifting a vehicle - they only help to level vehicles out when they are under load. Are you looking to level out the vehicle while under load, or for a legit lift? If you need an actual lift, then you'll unfortunately need to look elsewhere. If you are looking more for ride leveling, we do have options for you like the Air Lift LoadLifter...
