Air Lift Vehicle Suspension
- AL55FJ
Highlights
Custom Fit for Your Vehicle: Mounts to existing attachment points
7,500-lb Load Support: Levels your truck to cut squat and keep steering and braking steady.
Adjustable Air Pressure (5–100 psi): Fine-tune ride comfort and support for any load.
Built-In Jounce Bumper: Protects suspension when air bags are underinflated or empty.
Smooth, Stable Ride: Reduces sway, bounce, and road shock for better control under load.
Keep the Truck Level and Confident: 7,500-lb Load-Leveling Strength
Heavy trailers, campers, or bed loads can make your rear end sag and steering feel light. The LoadLifter 7500 XL Ultimate air springs add up to 7,500 lbs of load-leveling support to keep your truck level and stable. The 7" double-bellows design has up to 20% more air volume than smaller systems, so you get maximum lifting strength at lower pressures. With the truck level, braking, steering response, and headlight aim all stay right where they should.
Dial In the Ride You Want: Adjustable 5–100 psi Air Pressure
Every haul is different, so it helps to fine-tune your suspension for each setup. These air springs let you adjust pressure from 5 psi to 100 psi—inflate for heavy towing or drop to the minimum when unloaded for a smoother ride. You can inflate each spring independently for side-to-side leveling of uneven loads. Manual inflation valves are included and can be mounted on the bumper for easy access, or you can add a compressor system later for in-cab control.
Smooth Out the Rough Stuff: Internal Jounce Bumper and Roll Plates
When you hit bumps or run low on air, the built-in internal jounce bumper keeps parts from bottoming out or getting damaged. Air Lift’s upper and lower roll plates spread the load and protect the air springs themselves, adding durability and longer life. The two-ply fabric-reinforced rubber bags soak up road shock and sway so your truck feels planted instead of bouncy when towing or loaded down.
Built Tough for Real Work: Heavy-Duty Materials That Last
Everything about this system is made to take heavy use. The end caps are made of high-strength Zytel nylon, lighter and more corrosion resistant than steel, while the brackets and hardware mount solidly to your existing suspension. It’s a suspension upgrade designed for serious hauling and leveling with reliable performance year after year.

Easy install. Would recommend to anyone hauling heavy trailers. Especially with the newer Ford f350. Helped the ride while towing gooseneck and fifth wheel 100 percent.1444174

Well, let me start off by saying up front, that if you plan on installing this kit by yourself without a car lift, your going to be doing a lot! of crawling around under the vehicle. I started at 9am and finished at 5:30 with no breaks. Hard work for a 65 year old dude. Remove both tires and the spare for easy access. Whom ever put together the instructions for install did an absolutely excellent job! They were very easy to understand and concise. The photos where spot on and clear FOR MY VEHICAL. Not some generic photo that covers any vehicle. The kit was very well put together with all the parts required to assemble everything. I didn't have to supply or substitute any nut, bolt or fitting. Once the kit and the pump was finished being installed, I powered it up and inflated the bags. There where no leaks and everything thing worked perfectly. This is a first for most anything I install, seems like I most always screw up the installation or have to reengineer the kit to fit my needs. Not this time! Everything went together great and worked awesome. My hat's off to the team that designed and put this kit together and to Rochelle in customer service, who was professional and kind in helping me get the right suspension kit for my truck. Thanks to all the folks at etrailer you know what your doing and live up to they hype. BTW I learned about this kit on You Tube from a full time RV'er.3159833

I have a 2020 Ford F-250 Lariat FX diesel and I pull a 2022 Jayco Eagle HT fifth wheel with a GVWR of 10,995 lbs. I noticed when I was hooked up to my trailer and raised my landing gear the back of my truck would squat causing my headlights to shine somewhat into the sky and sometimes while traveling the interstate in construction zones the ride was rough. So I decided to add airbags. I chose the Air Lift Load Lifter 7500 XL Air helper springs(#AL55FJ). I had them installed by a local garage and he did a great job installing them. I love the end result a much smoother ride and the braking seems smoother also I can easily level off my truck with the 7500 XL Air lift system allowing my headlights to shine straight out now. I give these guys five stars.
In addition to adding the Air Lift 7500 XL system I also had the Air Lift Wireless Air compressor System(#AL58WQ) installed and it is Bluetooth, compatible on my iPhone which is amazing. I can control the lift on my bags individually or paired together with the touch of my phone. No stopping and getting out in the rain or looking for an air hose. I can sit in my cab or get out and increase or decrease the amount of air in my Air Lift system. I can also do it manually if I so choose. In the photo you can see where I mounted the two air fitting on my crossmember right below the compressor on the frame. There were already two holes there so and can be accessed easily. I am very satisfied with my compressor system and I give this a thumbs up in addition to the five stars.1292103
Hi Doug,
We offer the compressors separately from the air springs so there isn't a bundle price. For the air springs I'll first need to know if you have an in-bed fifth wheel hitch or gooseneck hitch installed and whether you have a 2WD or 4WD model? Let me know and I can pick out the right fit for your setup.
For the compressor I personally prefer the Air Lift WirelessAIR Compressor System for Air Helper Springs # AL74000EZ. This compressor comes with an EZ-mount design so you won't... view full answer...
I have a solution for you. As far as mounting brackets, the brackets for the 2827 air ride that you had on your 2017 Ford F-250 will not work on your 2022 Ford F-350. Unfortunately, the only Firestone air bag kit we carry that would fit your 2022 Ford F-350 is the Firestone Ride-Rite Air Helper Springs - Double Convoluted # F2176. Also, I confirmed with Firestone that they currently do not have any Air Ride springs that will work with your vehicle.
In addition, the brackets for the 2827... view full answer...
Hello Luke, thanks for reaching out. Since you have an F-350 I do like the Load Lifter 7500 kit. The springs are going to be more robust and you will not need to add as much PSI to get the same level of support.
Both the # AL55FJ and # AL86KV kits you mentioned are for the 2020 Ford F-350. The difference is the # AL55FJ is for single rear wheel models, while the # AL86KV is for models with dual rear wheels only.
I also recommend adding an onboard compressor like the Air Lift WirelessAIR... view full answer...
Hi Frank,
To add an Air Lift system to your 2022 Ford F-350 with dually wheels, I recommend using the Air Lift Loadlifter 5000 Ultimate Air Helpers Springs w/Internal Jounce Bumpers part # AL23DQ because they are specifically designed for 4WD dually models. This kit includes the air bags, brackets, and all necessary mounting hardware to mount these to your truck's frame without needing to drill. The air bags are rated for 5K of load support and have an internal jounce bumper, which both... view full answer...
Hello Zach, thanks for reaching out. The Air Lift # AL55FJ kit comes with 3 different sizes of lower leg adapters. From your picture it looks like you are using the smallest of the adapters which is why it is not contacting the axle. Switch them out for the larger adapters and it should resolve the issue. view full answer...
No, they do not Joey but I have a set that does. They are the Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs item # AL86KV. These are custom fit for the 2022 Ford F-350 duallys. They have a massive 7,500 lbs load leveling capacity and come with custom fit brackets.
The Air Lift LoadLifter 7500 XL item # AL55FJ fits the 2022 Ford F-350 but only the single rear wheel models.

Hello Sivan, thanks for getting in touch. Adding air bags is definitely a good call if you are unhappy with your Timbrens. The air bags will allow you to fine-tune the suspension to the perfect mix of ride leveling and ride quality. Then you can also retain the factory ride when you aren't hauling your camper.
The 7500 kit is definitely the way to go, and for that I recommend the following:
- Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs - Rear Axle # AL86KV

Hey Keith, thanks for reaching out!
The best Air Lift air bag suspension for your 2020 Ford F-250 Super Duty Tremor 7.3L is the Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs # AL55FJ because it has the highest weight capacity at 7,500 lbs. This won't increase the weight capacity of your truck (just the same as any suspension enhancement), but this higher capacity also means you don't have to fill the air bags up as much as the 5,000 lb kits to level out your truck.
I also recommend... view full answer...
Hello Wayne, thanks for reaching out. The Air Lift 5000/7500 can absolutely be installed in conjunction with your RAS system. The RAS system sits on top of the leaf springs so they won't interfere with each other. For your 2021 Ford F350 Crew Cab King Ranch I recommend the Air Lift LoadLifter 5000 # AL23FJ, or if you want to go with the 7500 use part # AL55FJ. The RAS kits do a good job reducing sway, so it would compliment the air bags nicely.
I also recommend adding an onboard compressor... view full answer...
Hey John! The correct Air Lift LoadLifter 7500 XL kit for your 2020 Ford F-350 with the Tremor package is the # AL55FJ. These fit as long as you have a single rear wheel model. I also recommend adding an air compressor like the Air Lift WirelessAIR # AL74000EZ. This will allow you to adjust the air bags from the cab of the truck no matter where you go.
Are you adding the air bags for towing or something else? view full answer...
The Air Lift LoadLifter 7500 XL Air Helper Springs item # AL86KV are designed to work with dually F-350's only. They will not fit the Tremor models or single rear wheel trucks.
The Air Lift LoadLifter 7500 XL Air Helper Springs item # AL55FJ are designed for single rear wheel F-350's.
Both of these air bag kits are confirmed to fit the 2021 Ford F-350. These systems have a 7,500 lbs weight capacity and are compatible with in bed hitches.

Hi Oscar,
I'm seeing conflicting information on the Tremor package, but from what I can see there should be about an inch lift compared to the standard models so you'll likely just need a spacer block. Air Lift recommends installing both the lower and upper mounting brackets, measuring the gap between them, and then subtracting the height of the air spring in order to find the correct sized spacer.
Air Lift offers the following spacers:
2" Lift # AL52420
4" Lift # AL52440
4" Lift Angled... view full answer...
The correct Air Lift LoadLifter 7500 XL kit for your 2022 Ford F-350 Tremor is the # AL55FJ. However, these air bags do not fit models with dual rear wheels. They will provide you with 7,500 lbs of load-leveling capacity and keep you level while towing or hauling.
Unless you really want to go with Air Lift, I actually recommend the Firestone Ride-Rite Red Label # F95FV instead. These have a superior construction which I think you'll appreciate since you're already looking for high capacity... view full answer...
Yes, removing items from the front of the trailer or rear of the vehicle will reduce weight over the rear axle but this would still not allow you to exceed any of the manufacturer's payload or GAWR ratings if that is the goal. These figures will remain unchanged from the manufacturer. That said, if you're having issues with a heavy pin weight we do have options to help mitigate these. I recommend the Air Lift LoadLifter 7500 XL Air Helper Springs part # AL86KV for DRW or part # AL55FJ or... view full answer...
For the highest load-leveling capacity possible for your 2022 Ford F-250 Super Duty 4x4, I recommend the Air Lift LoadLifter 7500 XL Air Helper Springs - Rear Axle # AL55FJ. Apart from the 7500-pound load leveling capacity of the LoadLifter XL, you will still be able to manually adjust the air bags independently for side-to-side leveling of off-center loads. Another great trait of the air bags is that they are made 100% in the U.S.A.
It is important to note that air bags are not designed... view full answer...
The Air Lift LoadLifter 7500 XL Air Helper Springs # AL55FJ are a confirmed fit for your 2020 Ford F-350 Tremor. I believe the fitment issues that they referred to were with the Kit # AL86KV that does not fit the Tremor. You should have no issues installing the # AL55FJ on your F-350.
I do recommend using the Air Lift WirelessAIR Compressor System # AL74000EZ to control the air pressure in each bag. You can set each bag to an individual pressure for uneven loads with either the included... view full answer...
Since you were looking at the # AL55FJ I'm assuming you want to add suspension enhancement to your 2015 Express 3500 Cutaway. There is a difference between the cargo van and the cutaway. The cutaway isn't an option in the vehicle styles but we do call out the products that fit the cutaway in the installation notes.
If you have a 159" wheelbase I recommend using the SumoSprings Solo Custom Helper Springs # SSR-206-54. These have a weight capacity of 2,800 lbs and will help absorb road... view full answer...
The highest capacity air helper spring kit offered for your 2012 and 2013 Ford F-550 Cab/Chassis trucks would be the Firestone Ride-Rite system, part # F2404 which provides 5600 lb of support. Neither Firestone nor Air Lift offer a higher rated system.
The # F2404 rides on the outboard side of the frame member, so in order for it to fit correctly, you'll need at least 9-1/2 inches of clearance between the frame member and the sidewall of the rear tire in order to have the proper clearance. view full answer...
Yes, the Air Lift 7500 XL air helper spring kit part # AL55FJ that you referenced is compatible with your 2022 Ford F-250 that has a B and W Turnoverball gooseneck hitch installed with part # BWGNRK1116. view full answer...
The application for each air helper spring kit is the difference.
The difference between the two is that the Air Lift 57552 which we carry as part # AL55FJ is for single rear wheel models while the 57550 which we offer as # AL86KV is for dual rear wheel model 2020 F-350 trucks. For your SRW model, you'd want to use # AL55FJ.
You might also be interested in an on-board compressor kit, part # AL25856 that would allow you to adjust the pressure in the system from the truck cab with the push... view full answer...
To install the Air Lift LoadLifter 7500 XL Air Helper Springs - Rear Axle # AL55FJ on your 2020 Ford F-250 you can expect it to take between 3-5 hours if this is your first time installing one of these kits. While it is not a very difficult install, it is good to take your time to make sure you are routing the air lines in a mannor that keeps them away from moving parts and heat, and taking your time overall carefully following the instructions.

For installing the Air Lift LoadLifter 7500 XL Air Helper Springs # AL55FJ on your 2020 Ford F-250 4X4 that is lifted they do make spacers. The spacers are available in different heights that you will need to confirm which is correct for your 3.5" Carli backcountry suspension kit.

For the 2021 Ford F-250 I recommend the Roadmaster Rear Anti-Sway Bar # RM93VR. You will need to contact Roadmaster for longer end links since you have a 6" lift and this sway bar requires that the forward leaf spring bump pads be bolted to the frame and not riveted.
We don't currently carry Hellwig products so I can't speak to their effectiveness when compared to Roadmaster.
