When the bed is packed or a trailer’s hooked up, the rear of your truck shouldn’t sag or throw off your steering. The Air Lift LoadLifter 5000 system adds up to 5,000 lbs of load-leveling support to the rear axle so your ride height stays steady. It evens out the weight across all four wheels, improving braking and handling while keeping your headlights properly aimed and your tires wearing evenly.
Every load is different, and these air springs adjust to match. With air pressure from 5 psi to 100 psi, you can fine-tune the support for towing, hauling, or unloaded driving. Inflate each bag separately for side-to-side leveling when a camper or uneven cargo shifts weight to one side. Manual inflation valves and air lines are included for easy access on the bumper, and you can add an onboard compressor system later if you want in-cab control.
These springs are made from 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion resistant than steel. Air Lift’s exclusive upper and lower roll plates shield the bags from damage and increase their load capacity. This design keeps leaks and rust out while extending the life of your suspension kit even under constant heavy use.
Everything needed for installation comes in the box—mounting brackets, hardware, manual valves, and air lines. Once installed, just add air through the valves and you’re ready to go. The LoadLifter 5000 includes a lifetime warranty with no mileage restrictions and a 60-day satisfaction guarantee for confidence that matches its heavy-duty performance.

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!
Product arrived in a short time and was easy to install in my driveway. Works GREAT!!!
Everything was as good as it looked.
One item was lost somewhere and was corrected when it needed to be.
Always fast and reliable service!
simple to install and works as advertised truck rides great with 2000 lbs in the bed 50 psi in bags
I put them on my F350, I took them off because when pulling my 30ft camper the truck road very hard, I tried different air pressure.
This item is just what I needed to balance the load. I can now move either my Fifth wheel or boat with the knowledge it rides level and supported.
Thank you
Great product. easy install. one bag leaks and I am looking to see where.
The airbags look exactly what I ordered. Not installed yet.

Highly recommend this product. Wonderful!!!
This Loadlifter worked excellent. Put a Lance camper at 2600 lbs. on my Ford F350 crewcab pickup. Despite the camper package option on my truck with extra rear leaf springs, it still pushed the bed end down and the hood side up in the air. Annoying side to side roll as well. The AirLift LoadLifter had very good instructions and was not difficult to install. Drilled five holes in the frame on each side to attach. Plenty of part options to make it a very good fit. Aired up the springs until the camper was perfectly level. Truck now drives level and considerably less side to side roll. This was well worth the price for the performance.
First time dealing with etrailer has been a great experience so far, I got 2 out of the 3 items, one of the items was a mix up but it was no concern was able to call and get connected with help within seconds, a huge thank you to will, he was great to talk to and very professional and was able to help with the mix up and got me in the right track with my original order. Shipping is fast and the tracking works great definitely a 10/10 for these guys!! I highly recommend
Honestly the bags seem to loose a little air after time. That being said could be a little leak on the plastic lines but don’t think so. The biggest complaint is the caps on the bags are pretty darn rusty for only being a year old. But they do work good with my truck camper. Thank you
Nice kit Good install Have very sharp drill bits, use oil to lube bits Slow and steady
