When you’ve got a heavy trailer or bed full of gear, the rear end can sag and throw off your steering and braking. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity so your truck stays level and stable under pressure. They balance the load across all four wheels, helping maintain safe headlight aim and confident handling even when you’re hauling serious weight.
Rough roads and uneven loads don’t have to mean bouncing down the highway. Each air spring has a closed-cell urethane jounce spring inside that absorbs bumps, resists bottoming out, and smooths out the ride. When air pressure is low, the jounce spring still provides support so you can keep moving until you can add air. The more weight you carry, the stiffer the jounce gets for progressive control that keeps your setup comfortable and steady.

Different loads call for different setups. With adjustable air pressure from 5 psi to 100 psi, you can fine-tune each bag to match what you’re carrying. Inflate both equally to level front-to-back or adjust them individually for side-to-side balance when your load is off-center. Manual inflation valves are included for easy access, and if you want more convenience, compressor systems are available separately for in-cab or wireless control.
Air Lift built these springs to last through years of towing and hauling. The 2-ply, fabric-reinforced rubber air bags use high-strength Zytel nylon endcaps that won’t rust or corrode like steel. Exclusive roll plates protect each spring from sharp edges and moving parts under the truck while increasing their effective load area for a smoother ride at lower pressures. All mounting brackets, hardware, air lines, and inflation valves are included for a solid install backed by a lifetime warranty and a 60-day satisfaction guarantee.

This system includes everything needed to mount directly onto your rear axle with simple hand tools—no complicated mods required. Once installed, just add air through the valves and go. Whether you’re towing a camper a few times a year or hauling bed loads every day, these Air Lift LoadLifter 5000 Ultimate springs give your suspension the support it needs without giving up ride comfort when empty.

Ratings & Reviews
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.
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.
Great service ! Very helpful thanks aga in
Solid fit. Good product.
Easy to install fits properly. Directions are pretty clear. Happy so far haven't had a chance to pull the trailer yet.
