When you’re hauling serious weight, squat and sway can make driving stressful. The Air Lift LoadLifter 7500 XL Ultimate air springs give your suspension up to 7,500 lbs of load-leveling support to keep things steady. Their large 7" double-bellows design carries more air volume than smaller bags, so they level heavy loads with lower air pressure. Steering and braking feel consistent, your headlights stay aimed right, and tires wear evenly—all while keeping your vehicle level front to back.
Rough roads or underinflated bags don’t have to mean damage or harshness. Each air spring includes an internal jounce bumper that safeguards the system if you ever drive with low or no air pressure. Upper and lower roll plates add extra strength at the mounting points, protecting the rubber bellows and increasing their load capacity. The springs absorb road shock for a smoother ride, reducing sway and bounce whether you’re towing, hauling, or driving empty.
No two loads are the same, so the system lets you tailor support exactly how you want it. Add air for towing heavy trailers or drop pressure for everyday comfort when unloaded. You can inflate each side independently for side-to-side leveling of off-center loads using the included manual inflation valves and air lines. Want more control on the go? It’s also compatible with onboard compressor systems that let you monitor and adjust pressure from inside the cab or your phone.
These springs are built for real-world use, not just show specs. The double-bellows air bags are made from 2-ply, fabric-reinforced rubber for strength and flexibility that lasts through constant loading cycles. High-strength Zytel nylon end caps replace steel to cut weight while resisting corrosion far better in wet or salted conditions. With heavy-duty brackets, hardware, and lifetime warranty coverage, this setup is made to hold up through years of towing, hauling, and every mile in between.

Always great dealing with trailer!
I've used Airlift on my old truck 2004 2500hd Silverado for Wolf Creek Camper worked great never had a problem on and offroad so much more stable and more control. So ordered another Set for my new truck Dodge 2500hd. And Airlift Company been really good to.
And again Etrailer.com have great customer service and fast delivery. Thxs
My air bags have helped stabilize my ride and keep my 5th wheel from rocking the truck. I have a 2019 Ram 2500 6.4 HEMI with coil springs.
I am very happy with the 7500 XL airbags I purchased from etrailer. The quality of the product was exceptional, the kits included everything I needed for the complete installation, and the instructions that were supplied with the kit were very specific in detailed. I've been in the trucking business all my life, and I know what works and does not work when it comes to supporting weight efficiently and safely. This kit met all my expectations and I recommend it to anyone who would need the extra support.

I have been using these 7500 lb airbags for a year now and have about 5 or 6,000 mi on them. Theyve done everything Ive expected them to do and Ive had no problems with them. There was obviously an adjustment period trying to decide how many pounds of pressure to put in them for my particular RV unit. Once I settle down on that, the entire rig road nice and level and was very stable. So far I have found no fault or drawback to these auxiliary suspension bags and would highly recommend them to anyone who needs the extra support.

Quality looks great. Instalation instructions could be better.
Just got them today and they are already installed! Super easy installation and they look amazing, can't wait to put some weight on them to see how they perform!
Easy install, perfect for my application, 2024 Ram 2500 4x4 with 35x12.5x18 tires, no rub.
Excellent product and easy to install.
Have dealt with e trailers on many occasions never disappoint with their customer service and support.
Installation went smoothly
Easy to install, so far working great!!
When I enquired about shipping due date due to snow storm delays, my order was located and delivered so quickly.
Installed at Dodge dealership. And made hauling four horses over the same week safer and more comfortable for me!
Everything was packaged very well. All parts were there and the quality is great! Save yourself some down time and put the parts together before you start taking your bump stops off. Prep time was about an hour to an hr and a half. Installed on a 2020 Ram 2500, very easy straightforward installation. The guy that does the video for etrailer does a great job for this application.
Relatively easy to install and they worked well on my first venture - towing a 37' 5th wheel with a Ram 2500. Going to modify the air tubing so I can adjust pressure to both bags at the same time, and they are always at the same pressure. It would be nice if a simple T fitting was provided with the kit to give that option during installation. At some point I will add an on-board compressor.
Easy install if you know how to use tools. You will need tall jack stands to do it right. The most frustrating part was running the air lines because I had to drop the spare tire. All in all it was a fun job
Great experience and product worked well.
I Highly recommend Etrailer.

Product is still working great! If you have a truck camper I highly recommend this product. Helps side to sway. And makes the truck a joy to drive. The truck is much safer to drive now.
They do the job
This is my second set, and I love them. Good price, good quality, easy installation, and very effective at leveling loads. I tow several different trailers, and I like that they are adjustable to different loads.
Shipping was really fast. The packaging will help if you guys put some paper or bubble wrap to protect the parts. Assembly was little bit challenging the manual making you running from left to right and back. YouTube video actually helped a lot. Installation was really smooth and easy. Over all it’s high quality product and everything works like supposed. Really happy highly recommend
I watched the installation video which was very good. The instructions that came with the product were also great. My 2019 Ram 2500 has very large tires and thank god my Son was here to help me. He did the heavy lifting. Installation went very smooth. The only problem was one of the nipples that screw into the bag leaked. I tried tightening it but that did not work. I ended up removing it and putting some yellow gas tape on it and reinstalled. It did not leak after that. I also installed a cigarette lighter in the bed of the truck and the inflation nipples nearby. I may install an inflation kit in the future but this manual method works for pulling my 5th wheel every month or so.
Work great, easy to fill.
Great product and super fast delivery. Everything was easy to install on my 2026 Ram 2500 Big Horn, Extremely pleased with Etrailer!
This was the answer to our problem with our Bigfoot 2500 Cabover Camper on our 2021 Ram 2500 long bed truck! The first time we loaded the camper on the truck it swayed terribly from side to side even at a low speed and was unsafe. After installing the air lift springs everything was fine! We are very pleased with them!

Even after a year These airlift load lifters continue to stabilize the ride. In fact, the ride’s gotten even better since we added compressed Styrofoam bedliners in place of the old system of two by fours and plywood. The camper sits firm and steady and the load lifters do their job and so easy to adjust. A pound or two here or there makes a real difference.
I'm a carpenter by trade and I'm always a little hesitant to do any kind of work on my truck. I usually take it to a mechanic and have them deal with bolts that don't want to break free and snap or not having the right tools at the moment. I did these air bags on my 17 ram 2500 in 2 hrs. You can literally do these with the tools every red blooded American man should already have. I pre-assembled them the night before on my tool bench and sprayed some penetrating spray on the old rusted bump stops. The next morning I install them on the truck and ran the airlines. I went back and forth between these and the timbermens. I don't regret these airbags at all. Plan on pulling a 37-ft travel trailer.
The airbags are great for towing, but horrible for everyday driving with no load on them. Even with 5 PSI they feel like a rock. One side does not hold air and soapy water does not reveal air bubbles, so I am at a loss where to start troubleshooting. The warranty says keep 5 psi in the bags which means I have to inflate every day on that side. Super inconvenient. When I have my trailer (29’ freedom express) the ride is phenomenal, so even with all that whining above the airbags help with sag and smooth the ride (600 lb) tongue weight on my power wagon 2500 which had a softer suspension. I hope this information is beneficial. Would be five stars if not for the leak.
This was a great upgrade for my 19 Ram 2500. Easily installed, had an issue with a leaking airline fitting but customer service addressed it and so far the bags have been operating on my truck for a year-and no complaints so far. Truck handles better when towing or cargo loaded into the bed. Highly recommend.
