When the back end starts to sag with a trailer or heavy cargo, the LoadLifter 5000 air springs step in with up to 5,000 lbs of load-leveling capacity. They help keep your vehicle level front to rear, which means steadier steering, safer braking, and headlights that stay aimed correctly. By spreading the weight across all four wheels, the system takes the strain off your factory suspension so it can handle heavy loads without bottoming out or bouncing around.
Every load is different. With these air springs you can adjust air pressure anywhere from 5 psi to 100 psi for the ride that fits your setup. Add more air when hauling or towing for firmer support, or drop it down when unloaded for a smoother drive. Each spring can be inflated independently using the included manual valves and air lines, letting you level side to side if your load isn’t balanced.
Durability is key when you rely on your suspension every day. These air springs use 2-ply, fabric-reinforced rubber that resists wear and road shock. The endcaps are made from high-strength Zytel nylon, lighter and more corrosion-resistant than steel, so they won’t rust or develop leaks over time. Air Lift’s exclusive roll plates protect each bag and boost load capacity while helping extend the life of the system.
Heavy trailers and uneven cargo can make any truck feel unsettled on the road. This system evens things out by reducing sway and absorbing road shock for a smoother ride. It helps tires wear evenly and keeps steering more predictable whether you’re pulling a travel trailer down the highway or hauling gear through town.
The kit comes with mounting brackets, hardware, manual inflation valves, and air lines so you can bolt it up and start adjusting right away. Once installed, you can easily add an optional compressor system later if you want in-cab control or wireless adjustment on the go.

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!
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
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!
Easy install
Quick shipment and delivery. Additionally the install was easy.
Easy to install. Works as it should
Easy install. Great quality!
Install wasn’t bad at all. Works great. Best purchase I’ve made for towing
We got our order in a timely manor. All parts are there. I give 4 stars so for for customer service and delivery. I'll update once installed
Quick and easy ordering. Installation will be done by my mechanic we shall see how it turns out. Hopefully it is just what the doctor ordered
Excellent product, fast and quick installation. Match perfectly to my truck, couldn't found anything else better.
After a year the air bags work great and the fitment is easy and works great. Thanks
Haven't made a long trip with a heavy load, yet. But they have smoothed out the ride with 5-10 PSIG. Had my grandson install them for me because I hate working on any car or truck. He had them installed in about 90 minutes including cleaning up and putting away my tools. It comes as advertised, no drilling required (except for the valves that had to be mounted in the bumper). I have 2 other trucks that I use working on our farm and I think I'm going to get a set for both of them.
Kit is well designed... However; Its a Premium priced kit with cheap hardware, steel nuts and bolts used instead of stainless - they will rust quickly, air fittings are cheap and air hose is obviously the cheapest they could find - very inconsistent in diameter and doesn't seal well in the fittings.
Direct bolt on kit. Directions made it easy to install. Truck sits perfectly level with over 8k trailer hooked up.
