Big loads can make the rear of your truck squat and throw off braking and steering. The Air Lift LoadLifter 7500 XL Ultimate air springs add up to 7,500 lbs of load-leveling support to keep things even. The 7" diameter double-bellows design has more air volume than smaller bags, which means stronger leveling at lower pressures for a smoother ride. With even weight distribution, your headlights stay aimed right, your steering feels steady, and your tires wear evenly even when the bed is packed or the trailer is hooked up.
Every load is different, and these air springs let you dial in exactly what you need. You can inflate each bag independently from 5 psi to 100 psi to level side-to-side or front-to-rear. That means you can keep your truck level when towing a fifth wheel or carrying off-center tools and gear without making the unloaded ride harsh. Manual inflation valves and air lines are included, and you can add an optional compressor system later for easy in-cab control.
Sometimes you forget to add air or unload faster than expected. The internal jounce bumper inside each LoadLifter 7500 XL protects the air bags and suspension if pressure runs low. It cushions bottoming-out impacts so you don’t damage the system when driving with underinflated or uninflated bags. Combined with durable 2-ply fabric-reinforced rubber construction and high-strength Zytel nylon end caps, these springs handle real-world use without leaks or corrosion.
When you’re towing heavy or hauling uneven loads day after day, durability matters. The included upper and lower roll plates protect each bag from abrasion and boost load capacity. Every kit comes with mounting brackets, hardware, manual valves, and air lines ready for install. Once set up, the system works alongside most fifth-wheel and gooseneck hitches to give your suspension the extra muscle it needs to stay level, stable, and in control no matter what you’re carrying.
LoadLifter 7500 XL Ultimate springs will not increase your vehicle's weight-carrying capacity. Do not exceed the manufacturer's recommended weight limit.

Installed easily , my truck handles so much better when towing 10k lbs . I wish I had added the long ago. The install videos helped a lot. Thank You
I have been using these for a year now, with several trips up and down the east coast. After a nice install and use, I have had no issues so far. I should get the compressor for the system though.
Had to do some adaptation for my application. I still need to run down a leak that started about two months after use.
Easy to install and works great. I have used air springs on my last three trucks and have had no problems with them.
Great product. The only problem I had was the sealant on the threaded elbows leaked under pressure. I had to take them back out and put more Teflon tape on them.
The product was as described, and the installation was a snap.
Hooked up my new fifth wheel camper to my F-250 with 25 psi of pressure in the bags, and truck did not squat at all. That was 2500lbs of tongue weight. 5600lbs rear axle weight. Extremely happy with the results thus far.
The 5000 kit did not cut it for my 350 dually with my lance 1171 on it. The 7500 was just enough.

Oh man.. that looks like one heck of a truck camper George. I would love to see photos of your setup if you ever get a chance!
I received the Air Lift system within a week of ordering and was able to install it in half a day with a little help. The drivers side is a little tight on space due to brake lines congestion going on. I decided to lower my spare tire which gave me room to sit up in that location for the install. Many of the pre assembly bolted connections I left snug for the install to make final adjustments then torquing them once everything thing was centered. I used the very helpful installation booklet that came from Air Lift and there was no need to look anything up on [online]. I suggest if you’re running the airline to your full door like I did run the passenger side first! If you don’t and cut the line in half as the installation booklet calls out you will not have enough line. I chose to run the passenger side first and had a little more than 4’ of line left for the driver side.
Great product, if you're pulling a gooseneck or 5th wheel you will be glad you installed this kit. Add the on-board air compressor for the best experience!
Product works as it stated.
Better yet the customer service from etrailer.com was the best experience for me.
Teresa confirmed the product was on the shelf and shipped it asap.
I make this comment because I purchased the product from 2 other sources that drop ship from Airlift the mfg and the service was horrible and I was very unhappy with Airlift. I will mention that 1of the 2 purchases was from Amazon and they shipped me product that was not complete.
Nevertheless....I have to say "Thank you" to Teresa. I will be using you for my source for my 22GN trailer parts in the future.
I have been using the airlift load lifter for a little over a year on my 2019 F-250 to haul a 2021 Grand Design Solitude 310 GK. The load lifter has performed flawlessly. My only recommendation would be to ensure you have another person to help with the install.
Installation is kind of a pain especially on the drivers side like all of the videos show but it works grate on my 2019 f 350
A year after installing this I'm happy to say that this kit is still working great. I use it to tow an 18k lb 5th wheel trailer (3200lb pin weight) with my 2018 F350 SRW and it rides so much better and safer.
Installation was a breeze, and everything seemed very high quality. It's been near the ocean it's whole life with frequent trips to salted snowy roads and there are no signs of rust. And with the larger air bags I can keep the pressure lower in them (60psi) and not have to worry about exceeding limits on hard bumps etc.
All in all I would buy these again, and believe they are an absolute must for anyone towing a large load.
I have had the airlift 7500 XL bags for a year now. I tow a 20,000 lb 5th wheel toy hauler. The airbags have given me no problem since installation. The compressor had to be replaced after several months but the warranty was great and swapped it out free of charge. No issues thus far on the new compressor. Very helpful when hauling and everyone should have one for safety concerns on the road. Too many people tow with the nose up and it's not safe
I purchased the Air Lift system for my 2020 450, not because it needed support to carry the load, but to get extra clearance for my 38' deck over that has storage boxes mounted under the frame and will drag if I go over un-even ground, off road. The bags were easy to install, I did in the driveway and it took about 3 hours or so. The only hard part was getting to one of the support bolts on the upper brackets. Just very tight and could have used an extra hand (smaller hand). I have been running empty so I keep the bags at about 6-7psi, when we took out the large trailer I had it at 70psi. I was not going to install a compressor or tank, but after the first run, I can see the advantage and honestly my last dully was set-up with one. The ability to adjust on the go, to dial in the ride you want is the way to go, so I did get a compressor and small air tank we will install over winter. I also like to have a small tank in-line with the bags, so thay have an expansion chamber and tame the ride. Generally I remove the overload spring when I install a system like this, I did not remove the overloads on this truck, and I'll have to see if I do or not. Generally they make the ride much nicer and it is not so hard to dial in the smooth air ride. Quality wise, the kit was great, all hardware present and very heavy built, feel like it is in-line with the 450 load capability.
Keeps the truck level rides better than the smaller air bag kits I tow a 39ft sundowner toyhauler with 2019 f250 with out any issues
These air springs kick butt! I carry a heavy truck camper on my F-350 and they can handle that and more. In addition when it comes to leveling at a campsite I can typically do so without a problem (I have an onboard compressor with remote which helps with that.). I’ll never come close to the capacity these airbags can handle but they are a solid addition to my HD suspension.

One year later and I’m still very happy with these airbags. They are rugged and probably overkill, but better that than under sized. They really are convenient for leveling at the campsite and adjusting for variable loads. Having an onboard compressor and remote adds greatly to the convenience but they are still easily adjusted with a foot pump and air gauge if necessary.
Very pleased with this product and would recommend it to anyone wishing to "level" a heavy load. With a 100psi capacity, it takes only 40 psi to level the truck back to stock ride height. Pressure drops to 15psi when empty, so I just leave it alone and check every couple of months. In one year, I have had to add a little air maybe twice.
Slight modifications were necessary to fit with factory installed 5th wheel prep. This was not indicated in the instructions or fitment specs. The folks at ETrailer and Air-Lift were very helpful in answering my tech questions during installation. The modification consisted of simply cutting a small notch in the top plate with my cuttoff tool.

Still going strong. If I ever replaced this truck, the first thing that would go on the next one would be Air Lift 7500xl
Helped make my towing much safer!
The system works well. Installation was an absolute nightmare and I would probably buy another brand due to just that alone. I cannot justify spending an additional $[XX] for a cheap pump with a wifi chip.
We just had the air bags installed today with only the trip home to test them. We think the ride is better without the fifth wheel. That test with the fifth wheel will be this weekend.
I installed the air bags because i have a slide-in camper that weighs over 4000 lbs dry. The combination of air bags and HD front and rear anti-sway bars improved the handling of the truck significantly. Well worth the time and expense.
I purchased the load lifter 7500. Etrailer was great easy to work with. Web site was easy to navigate and very informative. Product arrive quickly and was easy to install. I was experiencing an extreme sag, Tire wear and very un smooth ride once my trailer was attached. The load lifter product leveled my ride making for a smoother ride.Very pleased with my purchase. A few before and afters
Giving 4 stars because of packaging box had holes in it and all brackets were just thrown in box
I bought these for my 2018 F250 to pull 42ft sundowner toy hauler. They work great install little confusing on which way to slide them but there enough videos to figure it out.
I wasn’t going to buy compressor at 1st but glad I did. We took 1st trip in it this weekend and being able to adjust air for tanks empty to full is nice. Even riding with no load seems to ride better
Contact me few months down the road and let’s see how impressed I am
One day, I went onto the ET site and discovered the product was 40%. I had been contemplating buying the bags, as I had installed them on a previous truck I had. I installed them myself (and my nephew) in about 6 hours. We weren't rushing, as I had set aside the whole day for the installation. It's nice to have a second pair of hands outside the truck. The installation went well, except for the long carriage bolts on the driver's side and some confusion about which hole they went into. We initially picked the wrong one, which slowed the installation by disassembling the bottom plate to move them. All in all, the installation went well, and I am happy with them. They aired up fine. Now, to figure out what pressure to run them at.
Don't hesitate, get these on your truck. You won't regret it.

I still love them as much as I did on day 1. They have made a huge difference in the ride quality of my truck when towing. I run them with 12 psi in them. Now to add the on-board air compressor.
Do you have a question about this Vehicle Suspension?

If an air bag suspension is going to leak, it will typically do so at the point where the air lines into the fittings. Its crucial that when the air lines are cut to length, the cut needs to be perfectly perpendicular or it will leak. Brushing a solution of dish washing liquid and water on the fittings and then looking for the bubbles is the easiest way to locate the leak.
