When your truck squats under a heavy trailer or bed load, steering and braking can feel off. The LoadLifter 5000 Ultimate air springs provide up to 5,000 lbs of load-leveling capacity so the truck stays level front to back. The air bags take stress off the rear suspension, maintain safe headlight aim, and keep handling predictable when hauling cargo or towing.
Uneven pavement or rough roads can cause bounce and sway that wear you out fast. Each air spring in this setup has a closed-cell urethane jounce spring inside that engages when air pressure isn’t enough to support the load. The jounce absorbs bumps and road shock while reducing sway and bottoming out. It reacts progressively—the more you load it, the stiffer it becomes—so your ride stays stable and smooth even on rough terrain.

Every haul is different, so it helps to have control. You can dial in air pressure anywhere from 5 psi to 100 psi to match how much weight you’re carrying. Inflate both springs evenly for level towing or adjust them independently for side-to-side leveling when cargo sits off center. Manual inflation valves and air lines are included for straightforward setup, and the system is compatible with onboard compressors if you want in-cab control later.
This system is made to handle real work without leaks or corrosion getting in the way. The 2-ply fabric-reinforced rubber air springs are backed by high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion resistant than steel. Air Lift’s exclusive upper and lower roll plates protect each spring from moving parts under the truck while extending service life. Urethane internal jounces need no maintenance and perform consistently in hot or cold weather.

Installing these helper springs doesn’t require special tools or a lift bay. The kit comes with brackets, hardware, air lines, and manual valves so you can mount the springs, inflate them, and ride. Valves typically install on the bumper for easy access, or wherever fits best for your setup. Once installed, you’ll have reliable suspension support that adjusts easily whenever your load changes.
Ratings & Reviews
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.
Video and instructions being the same would be helpful. Ended up having to remove wire harness brackets on axle and remove tabs to clear air bags. Air bags improved drive ability greatly when pulling camper.
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.
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!
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.
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!!
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.
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.
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.
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
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.
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.
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.
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.
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.
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.
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.
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.
Great instructions and easy installation! Fit perfectly! Loaded my tractor to test them out and they completely leveled my sagging truck with 42psi.
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.
