When heavy trailers or bed loads push your suspension down, steering and braking can get sketchy. The LoadLifter 5000 air springs provide up to 5,000 lbs of load-leveling support to keep your vehicle level and stable when the weight is on. By distributing the load evenly across all four wheels, these air bags help maintain safe headlight aim, keep your tires from wearing unevenly, and reduce stress on your factory suspension so you can tow or haul with confidence.
Every load is different, and this kit lets you fine-tune your ride for each one. Set the air pressure anywhere between 5 psi and 100 psi to get the right balance between firm support and ride comfort. Inflate each spring independently for side-to-side leveling of off-center loads, or adjust both together for front-to-rear balance. Manual inflation valves and air lines are included, so adding air with a compressor or pump is quick and straightforward.
Heavy hauls come with rough roads, so durability matters. Each LoadLifter 5000 spring is built from 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that resist corrosion better than steel. Air Lift’s exclusive upper and lower roll plates protect the bags from wear and increase their load capacity. The result is a smoother ride that absorbs road shock, reduces sway, and keeps your setup steady mile after mile.
This kit includes the mounting brackets, hardware, manual valves, and air lines needed for installation. Once in place, it delivers full-time support without constant maintenance worries. The high-strength materials and leak-resistant design extend the life of your suspension upgrade. Plus, with a lifetime warranty and a 60-day satisfaction guarantee, you know it’s built to handle the long haul.

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 load my F350 just under its legal limit of payload with my 5th wheel. I had initially relied on overload bump stops to prevent sag, but the ride was far too uncontrolled for my liking. I have used Airlift bags in the past on a previous vehicle and loved them. I bit the bullet and installed them on my F350 SRW and could not be happier with the ride quality and control they provide. Instead of bouncing and bucking us out of the seat while destroying steering authority on the HWY, now I have control of my payload and a stock ride when I am unloaded. I should have gone with the bags to start and I cannot recommend them enough for all the 5th wheelers out there or anyone else who tows heavily on a regular basis. The kit supplied everything needed, although I added a simple piece of bar stock to mount the schrader valves. Very clear instructions that were easy to follow.
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.

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
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!
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!
Great product great service on time
Worked out as expected
Great product, a little challenging to install, but works as designed.
Arrived on time and is exactly as order ed.
Nice product, fast shipping and great customer service, I was notified every step from purchase to delivery. I would definitely recommend this company and product
Great product. Fast delivery and all the parts were there and good instructions for installation. Any novice mechanic can install them
This kit is awesome. I've had no issues with it at all. The Bluetooth compressor is a different story though
Best item ever to pull a Trailer of any kind .. Pulling 40ft 5th wheel, makes for easier driving.
Install was easy. Didn’t see many pictures online on how it would work with universal fifth wheel bed rails. Only problems I ran into was the rear studs for for universal fifth wheel rails were to short to go thru air bag bracket, and had to relocate mount for parking brake cables.
I am enjoying the product that has greatly improved my suspension support since I am carrying 2700 lb of pin box weight on my 39 ft toy hauler pulling with a 3/4 ton truck
I installed the product yesterday. It took 6 hours working alone including a trip to the village to buy a new corded electric drill. Installation required drilling 8 holes in the frame and 4 holes in the upper brackets. Anyone attempting this installation be wary of the brake line and wiring harness behind the driver side frame. My impression is that the kit is good quality and should provide excellent service. I am anxious to hook up the travel trailer and put this system to the test.

This is the best accessory you can buy for your truck. The regular springs require a lot of compression to contact the overload springs causing your headlights to be searchlights for the tree tops at the side of the road. These make the truck level despite the load. The only thing I would add is an air compressor and a leveling valve to make it fully automatic.
Made a big difference in ride when towing our heavy 5th wheel. Excellent product!
I think it's junk. Never has held air. It leaks off making it useless. I called trailer and they said I had to call the manufacturer. The manufacturer said there was nothing they could do. The install shop said the problem is with the connectors. They are cheaply made. They tried to take them apart and put some kind of sealer on them.didnt good. They said to see if the manufacturer could send different connectors. They said they don't have any.so after all this run around I'm out all the money with no air bags. And nobody cares.
