Features to know about

Stay Level and Confident Under Heavy Loads: Up to 5,000 lbs of Support

When your rear suspension starts to sag under a heavy load, stability and braking can take a hit. The LoadLifter 5000 air springs provide up to 5,000 lbs of load-leveling support to keep your vehicle level and steady. By distributing weight to all four wheels, they help maintain steering control, even headlight aim, and even tire wear when you’re hauling or towing. You get a safer, more balanced ride without the rear-end squat.

Dial In the Ride You Want: Adjustable Air Pressure from 20 to 100 psi

Every haul is different, and these air springs let you fine-tune how your suspension feels. Air pressure can be adjusted manually from 20 psi to 100 psi using the included inflation valves and air lines. Inflate each spring independently for side-to-side leveling when loads aren’t even. Add air for heavy towing days or drop down for smoother unloaded driving—all without changing out hardware or parts.

Built Tough for Real-World Use: Reinforced Rubber and Zytel Nylon Endcaps

LoadLifter 5000 springs are made from 2-ply, fabric-reinforced rubber with endcaps molded from high-strength Zytel nylon. This material is lighter, stronger, and more corrosion resistant than steel, so it won’t rust out over time. Air Lift’s exclusive upper and lower roll plates protect the bags from damage and boost load capacity, giving you dependable support through years of hard work and rough roads.

Simple DIY Setup: Brackets, Hardware, and Manual Valves Included

Installing real load support doesn’t have to be complicated. The kit comes with mounting brackets, hardware, manual inflation valves, and air lines—everything needed for a straightforward setup at home with basic tools. Mount the valves near the bumper for easy access, or pair the system later with an optional compressor kit if you want in-cab control. Once installed, just air up the bags to your desired pressure and hit the road with a level stance.

5,000-lb Capacity. Designed to upgrade your rear suspension, LoadLifter 5000 air springs provide high-quality, full-time load support. They level your vehicle, improving braking and ride comfort and reducing the strain on your factory suspension.

by:

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.



by:

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.



by:

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.



by:

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



by:

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.



by:

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!



by:

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



by:

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.



by:

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!



by:

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!

Fantastic, easy to install, great step by step installation instructions. Quality and value.



by:

Easy install great fit. Put them on our 04 E450 rv that we take to Old Mexico twice a year on some hideous roads. They’re worth every penny and rides so much better.



by:

I ordered this kit as an experiment for steading out the front to rear rocking that my van had. The regular van frame work did require drilling a hole in the frame that other Ford cab n chassis type vans may have. Either way it has been doing the job I needed it to do. I can keep a small rake on my van with minimal air or push it up a bit when my rear load gets a bit larger. I’m happy with this little experiment!!



by:

They were a game changer. My motor home rides so much better.



by:

I FIT THESE ON A NISSAN NV 3500. IT TOOK SOME WELDING ( THERE IS NOT A MODEL FOR THESE BUT MY MECHANIC KNEW HE COULD MAKE IT FIT). THEY ARE GREAT!! YOU CANT OVER LOAD THE TRUCK I KEEP IT AT 70 PSI. I ALSO FITTED AN ELECTRIC COMPRESSOR AND AN ADJUSTABLE 1/4 INCH REGULATOR AND DONT NEED ANY ADJUSTMENT.

  • Recommended Air Bag Kit for a 2017 Tiffin Allegro Open Road 36LA
    Hey Don, Air Lift doesn't but Super Springs do! If you're interested, the SumoSprings Rebel Custom Helper Springs # SSF-173-40-2 for the front and # SSR-183-54-1 would work great. The front springs have a 3,000 lb capacity, the rears have a 7,000 lb capcaity at 50 percent compression, and will work in temperatures of -25°F to 200°F. If there is anything else I can do for you, please feel free to drop a comment and let me know!

  • Best Air Bag Kit For 2004 Ford E450
    Hey Allen, thanks for reaching out. We do have air bag kits for the 2004 Ford E450, but the # AL88205 kit you were looking at is for Chevrolet motorhome axles, so you will need something different. There are a few potential fits for the 2004 Ford E450, so I will need you to confirm a bit more info. For example, the Air Lift LoadLifter 5000 # AL57131 will fit Ford E450 class C motorhomes with a GVWR less than 14,050 lbs. This kit has brackets that are specially designed for vehicles...

    The pins are going to be easy. You'll need the Replacement Rail Pins and Clips item # C16902. This kit includes everything you need to attach your A16 Hitch to your 5th wheel rails. The hardware for the 5th wheel rails is going to be a bit more difficult to source because they are part specific to whatever set you already have. Additionally, the hardware is not sold by us individually. It only comes with the brackets like the Curt Custom, No-Drill Fifth Wheel Bracket Kit for Ford F150...

For the 1999 3500 dually your options are limited, and this will be the best available for your truck. The 5000 Ultimate kit comes with stainless air lines.

    Hey Trip, For a 2014 Chevy Traverse you would need the Air Lift 1000 Air Helper Springs for Coil Springs # AL60816 instead. The # AL57131 you were looking at is designed for specific motorhomes. You would fold these over and slip them into the rear coil springs and then air them up to compress them against the coil springs.
