When your trailer or bed load starts to weigh heavy, rear-end sag can throw off your braking and steering. The LoadLifter 5000 air springs provide up to 5,000 lbs of load-leveling support to keep your truck level and stable. By distributing weight evenly to all four wheels, they improve braking performance, handling, and headlight aim—so every haul feels safer and more predictable.
Every job or trip puts a different demand on your suspension. With adjustable air pressure from 5 psi to 100 psi, you can dial in the exact support your load needs. Inflate both springs together to level front-to-rear, or air them independently for side-to-side leveling when loads are off-center. Manual inflation valves and air lines are included, and a compressor system can be added later if you want in-cab control.
These springs are made with two-ply, fabric-reinforced rubber and endcaps molded from high-strength Zytel nylon—lighter, stronger, and more corrosion resistant than steel. That means no rusted caps or leaks over time. Air Lift’s exclusive roll plates protect the air bags from damage while increasing their load capacity, giving you confidence that the system will hold up through years of towing and hauling.
Heavy loads can make your suspension bottom out or cause sway and bounce on rough roads. The LoadLifter 5000 cushions road shock and reduces sway for a smoother ride whether you’re towing or carrying gear. By taking strain off your factory suspension, it helps keep tires wearing evenly and steering response steady even when the bed or hitch is maxed out.
This kit includes mounting brackets, hardware, air lines, and manual inflation valves—everything required for setup with basic tools. Once mounted, it’s as simple as inflating the springs through the valves typically installed on the bumper. Air Lift backs it with a lifetime warranty and a 60-day satisfaction guarantee for extra peace of mind once it’s on your truck.

Installation was not difficult. Excellent for the intended purpose of leveling the vehicle with a bumper pull RV trailer connected. Has made the ride for the rear seat passengers uncomfortable when not towing. Have not found a PSI that alleviates this.
The airbags did their job! I’ve got a 2021 Toyota Tacoma, and I’m really happy with the results so far. I only had to put in about 10 psi, and that was more than enough to handle the weight of the dump trailer. The install was a bit tedious and took around 3 hours total. The left side definitely took longer than the right.
The installation was not that difficult. I did not use the wire harness bracket supplied, my 2024 F250 I unplugged the harness form the truck sided bracket all the lines run up to and rerouted the harness much cleaner installation
Installed yesterday and tried them out with the fifth wheel loaded. Leveled my truck out in seconds with a compressor. The installation video on the same page as the product was extremely easy to follow. Also, Joy was awesome with helping me select what I needed over the phone. Very happy with this.
I installed the airbags on my 2015 Ford Transit to help with the heavier weight after converting it to an RV. The airbags were fairly easy to install. All the parts were included with the kit. I chose to use the manual inflation option by running the air tubes to the back of the van and mounted the fill valves under the bumper. There is a noticeable difference in the sway of the van going around corners and the sag in the back of the van when fully loaded. It's easy with a bicycle tire pump to adjust the firmness of the airbags. A great addition to the safety of the van.
Put these on my 2022 Ford F250 to assist with pulling my 5th wheel. Watched the etrailer YouTube video along with the instructions installation went smoothly.
I can’t believe how much putting these rear springs on my 2021 Jayco Alante Class A has helped the whole suspension and ride.
We took the RV all the way to Alaska through AB, BC, and Yukon Canada. I started with low pressure at 60 psi to see how it performed but ended up having the air set at 80 psi. I would definitely recommend these to anyone with a Ford F-53 suspension who struggles with the ride and comfort.
I just completed the install of this Airlifter 5000 series air bag kit. First, the kit, without a doubt, is a high quality kit with many of it's components designed specifically for specific vehicle application. I installed it under the rear of our new-to-us 2021 Ram 1500 Crew Cab Laramie 4x4 Ecodiesel. I was very pleasantly surprised by the nice and robust powder coating of the metal mounting plates. That means protection for them for a long, long time. The hardware/fastners were/are of decent quality also. And, while the "springs" used for the temporary carriage bolt retention in part of the install are a good idea, I have maybe a better way of doing that. In my opinion, for whatever that's worth, here's a suggestion.
Since there are TWO of those carriage bolts that have to be installed AT ONE TIME, you now have to deal with those two long tailed springs, carriage bolts that continue to fall backwards into the abyss of the frame, all the while trying to maneuver the frame mount plate into position. Then, trying to retain tension on the tails of those springs that retain the carriage bolts, and align the bolt tips to enter the mount plate, and then, if and or when you get the mount plate into position and both bolt tips are protruding through it, you now have to hold ALL of that in place, while you remove at least one spring so that you can now grab a nut (a feat unto itself) and fit it onto the tip of one bolt, all the while trying to hold tension on that bolt so it won't fall backwards into the frame and start threading it.
Then, once it's threads are started, you can no concentrate on the same operation for the second bolt. What a serious pain in the petute!
But instead of the springs and tails to be used to retain the bolts while prepping to install the mount plate, you use whatever their called, a very, very thin retainer clip or washer or "push clip" (I really don't know the name of them) that are used to retain the drums onto hubs on an axle, ALL THOSE PROBLEMS would be over.
You'd simply use the springs as before to load and pull the bolts through their respective holes as before. Now, with the one bolt in place, reach through the center hole in the frame that's between the two bolt holes and using a finger, push on the head of that installed bolt. Your finger will now hold the bolt in place. Now, with that bolt held in place, you can remove the spring. Then, PUSH the very thing spring clip right over the threads of the bolt and it will "ratchet" down the threads until it bottoms out against the frame. You have now LOCKED that bolt in place and you can let got of it with your finger and that bolt isn't going anywhere!!!!!!!!
Now, do the same for the second bolt. Now, both bolts are held firm in place WITHOUT the long and cumbersome tails of the springs. You can now grab the mount plate and push it up into place and over both exposed sets of threads at the same time WITHOUT FEAR of pushing the bolts back into the frame. You can now hold that mount plate in place while you grab one nut at a time and thread it all the way on. Then do the same for the other nut.
To me, this would be waaaaaaaaaaaaaaaay easier than the method you (and I, and any installer, be it a shop or a home install) are presently using. If I had a link to what kind of clip I'm talking about, I'd link it.
But, those clips are seriously thin yet are quite capable of retaining those bolts and will not hinder the mate-up of the mount plate to the frame sides. Sure seems worth a looking into to me. Just a suggestion.

These were a great addition to my truck. I moved from Washington to Michigan 1 year ago. Heavily loaded trailer and truck. No sag, no issues. Full disclosure I had to get some custom U bolts made because of my setup, but I have had zero issues. Great buy.
I plumbed my airlines through the license plate which turned out to be very handy.
I didn’t do the install myself. However my mechanic talked me into these after adding a rack and rooftop tent to my ‘14 Tacoma. Absolutely Fantastic. I have a 3” suspension lift and the truck handles as near to stock as I can remember. Awesome product. Easy install (according to mechanic). Thanks all. Oh yes, one issue because I added a leaf spring when I lifted it. He had to find new shackles to allow for fit. FYI
Install on a 2026 F350 SRW. Love the product and have zero issues with that itself. The reason for the 4 star is the clearance with the factory sway bar and brake lines. It does mention that in the instructions, however it's extremely tight and I'll definitely be checked for rubbing in the future to make sure I don't have clearance issues. Otherwise, they work great paired with the Airlift WirelessAIR compressory system, zero complaints on the usability of the product.
Took my time and followed included instructions exactly. Went together well! Haven’t towed with them yet, but definitely raised the back of my Tacoma with 26 lbs of air pressure that I tested for leaks with! Feel like they’ll be a big improvement when towing our 4200 lbs. camper!
Very easy step by step instructions, how to install.It took me about two hours in my driveway. I got it because I haul a 35' travel trailer. Makes the ride a whole lot smoother
a very good choice. The F150 did not have enough stock suspension for my 24 foot trailer with a GVER 10,000lb. Now we all know the truck will pull that weight but when you hooked up it squatted.After installing the air lift it does not squat any more and the truck with a 5.0 has enough power to pull the weight. I had Monroe air shocks on it before but they would not do the job. I am very happy with the setup. I replaced the Monroe air shocks with Rancho shock's and the ride is amazing with or with out the trailer. This was a great investment for the long haul.
Watched the install video twice before the shipment got here and had no problems installing it. Also installed the WirelessOne from Airlift at the same time. Picked up some 1/4" clamps to make the air lines look a little cleaner, and hold them in place during our snowy and icy winters. Including the WirelessOne system, it took about 8 hours from the time I washed the underside of the truck until I rolled it back out from the garage. Pulled the camper this morning and all my old issues have disappeared. Truck is level, trailer pulls great, and the cooling system is back to working as needed. Highly recommend this suspension kit!
Im very impressed with these airbags. So far they are doing the job.
These come with all hardware and instructions. I put 20 psi with no load to see how long the air would hold up. 2 weeks later im now at 15 psi which I'm satisfied.
The previous bags of another brand didnt hold air well even with no leaks.
I can tell the difference in ride quality. I've loaded the bed with landscaping materials and towed my boat with 15 psi and still holding strong. Looking forward to towing my Travel Trailer.
Customer service has also been great!
Shipped quick everything good
Easy to install and appearance looks great and they work like they dhould
Had to modify to make it fit. There was not enough clearance between the axle and the frame. It would bottom out with 25 pounds of air
It works like advertised.
First thing is e-trailer the best to buy from , hands down! Air lift 5000 not a great kit in my opinion . This is not my first air bag install , over 12 so far. Brackets look good , bags fit them good and hardware is ok. The problem is the upper bracket is 3/4k inch short of sitting against frame . Jounce cup is in the way , I tried to mock it up in place but hardware is to short . Jounce cup had to be removed for bracket to fit up to frame , it's welded on . This kit is not what I would average to install . I'll try a different manufacturer next time. 2009 chevy 1500 4x4 crew cab .
Had to do a little grinder modification on a couple brackets but overall worked great. Hauls my 26’ trailer great
