    • Lets you temporarily carry a load with zero air pressure in your springs
  • Quality construction for long-lasting spring life
    • 2-Ply, fabric-reinforced rubber air springs are durable

  • Mounting brackets and hardware are included for installation
  • Manual inflation valves and air lines are included
    • Manual valves are typically mounted on bumper for easy access
    • Compressor system with in-cab gauges (sold separately) can be added to monitor and automatically adjust air pressure
  • Made in the USA


Specs:

  • Load-leveling capacity: up to 5,000 lbs
    • LoadLifter 5000 Ultimate springs will not increase your vehicle's weight-carrying capacity. Do not exceed the manufacturer's recommended weight limit.
  • Adjustable air pressure: 5 psi - 100 psi
  • Lifetime warranty
  • 60-Day satisfaction guarantee


Note: When servicing your truck with Air Lift air springs installed, if the truck is lifted by the frame, the air must be let out of the springs. And if the rear of the truck is lifted during service, then it must be supported by jack stands to avoid damage to the air springs.


Get the Best of Both Springs

The air springs and jounce springs in this system work together to give you the best ride whether your truck is loaded or unloaded. Air Lift's LoadLifter 5000 Ultimate air springs have internal urethane foam jounces that protect the air springs and provide added ride comfort when your air pressure is low. The jounces also allow you to temporarily carry a load if the air springs lose air pressure. This gives your 1/2-ton, 3/4-ton, or 1-ton pickup air springs that are easier to maintain.


Air Springs Level Your Load

Carrying heavy cargo in your truck bed or trailer puts extra stress on your truck. Your brakes erode faster, your tires wear unevenly, and handling suffers severely. When towing, you might also experience excessive sway, bottoming out, and even inaccurate and unsafe headlight aim.


By pairing your existing suspension with LoadLifter 5000 Ultimate air springs, you can seriously beef up your suspension, ensure equal load distribution, and get the support you need. The springs provide up to 5,000 lbs of load-leveling capacity (depending on the weight-carrying capacity of your vehicle) and distribute the weight of your payload to all 4 wheels. As a result, the stress on your factory suspension is significantly reduced. LoadLifter's air bags are adjustable from 5 to 100 psi for precise support, and they can be inflated equally for front-to-back leveling or independently of one another for side-to-side leveling.


The air springs are made of high-quality, 2-ply, fabric-reinforced rubber. Most air bags lose air at the ends where the bag is enclosed with steel caps. These caps can rust and corrode over time, creating small holes. But the endcaps on Air Lift air bags are fashioned from corrosion-proof Zytel nylon, a material that is both stronger and lighter than steel, ensuring that the air bags won't lose air.


Roll plates on Air Lift 5000 Ultimate air spring

The air bags also have Air Lift's exclusive roll plates, which protect the air springs and beef up their load capacity. These sturdy plates help guard the springs from moving parts under your vehicle that might puncture the air bags. The plates also provide a larger surface area for each spring to roll on. The extra surface area gives you a higher spring rate at a lower air pressure, resulting in a better ride.


Built-In Jounce Springs Add Control and Comfort

Air Lift 5000 Ultimate air spring with jounce spring inside

The closed-cell urethane jounce spring inside each air spring gives you a more stable, comfortable ride. Each jounce acts as an overload spring and engages when your current air pressure level isn't enough to support your load. So on a rough road, the springs will kick in if needed to absorb bumps and shocks and help you to avoid bottoming out. When the jounces support a load, they adjust progressively - the more weight you pile on, the stiffer they become. The urethane material engages more smoothly than rubber jounces so you get a less jerky ride.


Because these jounces are taller than your factory jounce bumpers, they engage sooner than your factory jounces would to provide better support. And if the LoadLifter 5000 Ultimate air springs have insufficient or zero air pressure, the internal jounces will help to temporarily support your suspension and protect it from damage until you can repair or adjust the air spring system.


Easy Installation

This system installs with the included brackets and hardware. Just mount the springs, inflate them, and ride. To inflate the LoadLifter springs, you just have to pump in air through the inflation valves. A line kit is included with the springs so that you can install the manual inflation valves (one for each spring). These are typically mounted on the bumper but can be installed anywhere that is easily accessible. If you want to make the springs even easier to use, you can get a compressor and gauge system (sold separately) that allows you to monitor and adjust the springs from the cab of your truck.


Lifetime Warranty

Along with a lifetime warranty that has no mileage restrictions, Air Lift offers a 60-day satisfaction guarantee. Just install and use LoadLifter 5000 Ultimate springs for 60 days, and if you are not satisfied at the end of this time, you can remove and return them for a full refund.

Video Transcript for Air Lift LoadLifter 5000 Ultimate Air Helper Springs Review

Speaker 1: Today we'll be taking a look at the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers for the rear axle. See etrailer.com for your truck's fit.Now here's what our airbags look like installed. The reason you're gonna want airbags on your truck is because if you're towing a heavy trailer or have a heavy load in the bed of your truck you want to maintain your factory ride height. As we add weight to the back of the truck, the back will go down and the front end will come up, and this affects a few things. Number one, it affects our headlight angle. Our headlights are now facing more towards the sky and we could potentially blind oncoming drivers, and where they're not aimed down properly at the road like they should be.

Also, it'll take weight off the front end of the truck so we have less steering and handling capabilities. It'll also cause a little bit more front tire wear because the front tires now develop positive camber as the weight's taken off of them, so it'll cause more wear to the outside edge of your tires.Another side effect of this is as we take off the weight from our front tires, our front brakes are no longer capable of working at their peak efficiency because our front brakes do the majority of the braking on our truck. That's where our Air Lift LoadLifter 5000 Ultimate Air Helper Springs come in. By pairing your existing suspension with LoadLifter 5000, you can bring your ride height back towards stock so you don't have to worry about your handling characteristics or your steering, or your braking abilities being affected when you're towing that heavy trailer or have a heavy load in the bed of your truck. This will make for a smoother and a safer ride.Now, what many of our customers like about these airbags compared to other ones on the market is that these have an internal jounce bumper inside.

So, even though we are replacing the factory bump stop, the jounce bumper inside here will still act like it for when we have full suspension travel, so we're not sagging down and having a very harsh ride when contact that. Now, these airbags are designed to work between air pressures of five and 100 PSI. The more air that you put in them, the more weight leveling capability that they have. They will support up to 5,000 pounds of weight, whether that be from a pin weight of gooseneck or a fifth wheel trailer, or having a large load in the bed of a truck. And they can be inflated equally for front to back leveling or independently of one another for side to side leveling.The air springs are made of a high quality two ply fabric reinforced rubber.

The airbags have Air Lift's exclusive roll plates, which protects the air springs and beef up their load capacity. These sturdy plates help guard the springs from moving parts under your vehicle that might come through the airbags. The plates also provide a larger surface area for each spring to roll on. The extra surface area gives you a higher spring rate at lower air pressure, resulting in a better ride.Our customer, Kevin M., says, "This was a great addition in my 2011 Ford F250 King Ranch. Instructions we're clear, and installation was not too difficult.

Ride is very good whether pulling my fifth wheel trailer or not. I really like the internal jounces so that I can maintain minimal air pressure during normal driving."And, now we'll take our airbags out on our test course. On the left side of the screen, you'll notice the vehicle without the airbags installed. And on the right side of the screen, you'll notice the vehicle with the airbags installed. The first part of our test course, we'll be doing some evasive maneuvering, doing some quick turns and side to side. You'll notice how unstable and unsettled the suspension is without the airbags installed, and with them installed, you'll notice how much more settled and more control we have over the vehicle. There is less body roll than we had without them.And the next part of our test course, we'll be going over some bumps, and you'll notice without the airbags installed how much suspension travel we don't have. The suspension can't do its job properly because it's sagging down, and doesn't have the amount of travel that it needs in order to help absorb the bumps. With the airbags installed, you can see how much less jouncing and jarring there is going on. It's because the suspension is able to do its job properly with having the weight being supported by the airbags. This will give us much more handling and braking ability with the airbags installed, giving us the safety that we need when we're towing a heavy load or have a lot of weight in the back of our vehicle.And that completes our look at the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers for the rear axle.

Can’t say enough good things about etrailer.com, it’s professional and courteous staff and the quality products they carry. This is the second pair of Air Lift Ultra 5000s and associate hardware (extra hose kit and t-fittings). I normally call sales when I order just to make sure the product(s) I’m ordering are in stock and especially if I have a lower price compare, it seems to expedite processing and delivery. Special thanks to Tammie (Sales) and Sarah (Customer Service) for their over-and-above assistances and quick processing. My order was on the way immediately and received in great shape in 3 days. Definitely a satisfied customer! 667525

I haven't tested the air bags thoroughly but they seem to be working as designed. Install was pretty easy. The air bags and compressor kit should all me to better manage the weight of our fifth wheel with or F250. E-trailer is an awesome company to deal with. The ship fast and follow up on orders.

Ordered and received in two days! Installed today. Took 5 hours which is not bad for a 62 year old with two arthritic shoulders and a bad back. Instruction were followed. I did wrap the carriage bolts on right side to protect the brake line. Will test with RV attached to see how my truck rides. 617903

It has changed the ride on my vehicle for everyday driving. It is a very rough ride. 667714


Comments
The nice feature of air springs is that you can custom tailor the ride to just about any situation. Carrying a full load?- Add more air for less sag and more stability. Less weight on the vehicle when youre not hauling? - Let some air out of the suspension for a softer, more pliable ride.

Review from a similar Air Lift LoadLifter 5000 in Vehicle Suspension


High quality and heavy duty. Good instructions as well. Just got them installed yesterday on my 2009 F-150 crew cab with 6.5' box. I also have the B&W turnover gooseneck ball hitch and my main concern was still being able to mount these. Fit like a charm, no interference at all. I wish I would have purchased them sooner. Sometimes we haul loads that might be just a bit heavy for an F-150, but we are careful. These will certainly help. I have similar air bag type suspensions install on our other two work trucks and I love them. What I did was got myself a 1/4" compression tee and plumbed both air bags into one valve. That way, they air up evenly. It comes with everything to air up each bag separately but I prefer them to be the same. They cost about $6 at any hardware store. I mounted the single air fill valve near the drivers tail light inside the box facing forward. There is an opening where the tail light harness runs up and I followed that with the air valve. I drilled a hole and snaked a tie wire down and through some finagling I managed to get the valve out the hole and mounted. Looks good and is out of the way. Install took me about 5 hours from tools out to tools away, but I was not in a big hurry. I aired them up to 70 psi and drove home looking like a hot rod with the back kicked up. Checked the air pressure this morning and all is well. No leaks as far as I can tell. Highly recommended and a great price as well. 643462

Review from a similar Air Lift LoadLifter 5000 in Vehicle Suspension


Have had the air bags installed for 3-4 weeks now. Love them! Huge difference in ride quality when hauling or towing heavy loads. My only criticism is in the design. The left side fit perfect and the bag is perfectly aligned vertically but the right side bag is canted slightly. Almost as if the bottom brackets holes are drilled slightly off. I called the company and was told that up to 15 degrees is acceptable. It just looks as though the bag may wear more but time will tell I guess. I would still recommend. Also looking at purchasing the compressor system to ensure the bags always have adequate pressure. 421216

Review from a similar Air Lift LoadLifter 5000 in Vehicle Suspension


I have a 2019 Nissan Titan XD with the 5.6 GAS motor. Wanted to do an Airlift suspension to provide a little support and get my headlights perfectly back to level when towing my travel trailer. No one makes an airbag kit for the gas XD, but after discussing it some with John H at etrailer, I decided to go with the kit for the diesel truck and see how things went. The kit for the diesel truck fit perfectly, except that there is an emissions component hung from a bracket on the driver's sign frame that prevents a direct install of the driver's side bag. My shop was able to install the kit with no trouble - they just had to bend the bracket with the small emissions component attached upwards for clearance. Everything else went in as designed. Great fit - can't wait to see it work under load. 669525

I have had the air bags installed for over a year now. From the boat ramp, camper and dump trailer these things just work GREAT. I will add a set of these to every truck i owe from now on! So nice to be able to level you truck out regardless it being a large or small load. They truly give your truck a safer ride when towing! 526431

One year later I still like these airbags.My truck rides level and handles smoothly. Without a load, however, its stiff in back and bounces, even with the airbags deflated.

I recommend the Air Lift LoadLifter over the other options because they are designed with internal jounce bumpers.

  • Can Air Bag Helper Springs be Installed on a 2017 Ford F-250 with Factory 5th Wheel Prep Package
    Air Lift helper springs # AL88399 have an upper bracket that mounts to the bottom of the frame on the 2017 Ford F-250. Provided that no part of the OEM 5th wheel prep package uses this space you can install it on your truck. Basically the upper brackets install in place of the factory bump stops above the rear axle. If you check that area, specifically the frame area it is mounted to, it should be clear meaning the system will fit.

The best suspension enhancement for this truck is going to be the SuperSprings Custom Suspension Stabilizer and Sway Control Kit # SSA25; I checked with SuperSprings and this kit is a fit for your truck. This kit is a helper leaf spring which has different settings which allow you to choose the best...

  • Air Lift Airbags and Compressor Kit Compatible with a 2018 Ford F-350
    I called my contact at Air Lift and was able to confirm fitment of the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers for your 2018 Ford F-350. If you have the two wheel drive (2WD) version then you will want to use part # AL88391 but if you have the four wheel drive (4WD) version then you will want to use part # AL88399. Both of the above systems will work well with the Air Lift QuickShot Compressor System for Air Springs part # AL25572.

  • Will the Air Lift Air Bags for a 2018 Ford F-350 Work with a 5th Wheel Hitch
    Yes, the Air Lift LoadLifter 5000 Ultimate Air Helper Springs part # AL88399 will fit your 2018 Ford F-350 with most above bed base rails. The reason for this is because the air springs install underneath the frame rails whereas the brackets for most base rails install on the side of the frame. Please keep in mind that this kit is for four wheel drive models. If you will be towing frequently then I recommend adding a compressor kit like the Air Lift Load Controller Compressor System...

  • Compatibility of AirLift LoadLifter 5000 Ultimate Air Helper Springs in 2017 Ford F-250 Diesel 4x4
    For your 2017 Ford F-250 4x4, the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers # AL88399 is a confirmed fit.

  • Missing Lower Bolt Hole On Lower Bracket for Air Lift LoadLifter 5000 AL88399 On a 2019 Ford F-450
    It sounds like you have the old version of the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers part # AL88399 which only has two holes on the lower bracket instead of the one you need with three holes. If you used our site for the fit info and then purchased elsewhere you could very well run into this issue as other manufacturers will keep old stock and may not be aware of this issue but I can confirm if you order from us, you will receive the new lower...

  • Air Lift LoadLifter 5000 Ultimate Air Helper Springs Compatible with 2016 Ford F-250 Super Duty
    Air Lift does make a kit for your 2016 Ford F-250 Super Duty, however, the # AL88399 is not going to work since it's only compatible with 2017-2019 Ford Super Duty pickups. The correct Air Lift LoadLifter 5000 Ultimate Air Helper Springs for your truck are part # AL88395 for 2 wheel drive, or # AL88396 if you have a 4 wheel drive. Unless the lift on your truck is a body lift, you'll need a spacer kit as well. If your truck does have a suspension lift, measure the distance between...

  • Does Air Lift LoadLifter AL88399 Fit Single or Dual Wheel 2017 Ford F-350 Trucks
    The Air Lift LoadLifter system # AL88399 is designed to fit the 2017 Ford F-350 4x4 single wheel or dually applications. So as long as your truck is a 4x4 it will fit. If it is a 2-wheel drive model there isn't an air spring kit available just yet.

  • Using the AirLift Load Lifter 5000 Ultimate on a 2017 Ford F-250 Super Duty with OEM Puck System
    I reached out to AirLift, and they confirmed that for the AirLift 5000 Ultimate, part # AL88399 will work with a factory installed puck system on your 2017 Ford F-250 Super Duty I've included a video review of this kit so you can get an idea of its features and benefits.

  • Air Bag Suspension Enhancement Recommendation for 2017 Ford F-250 that Won't Add Height
    The jounce bumper in the # AL88399 can cause a slight increase in ride height even when the bags are uninflated. There is a much better option for you since you do not want any additional height. Instead you'd want the Firestone kit part # F2600 which will not add height when uninflated and actually will give you a higher quality air bag. This would be your best solution.

  • Can I Use Airbag on a 2019 Ford F-250 with the Factory Prep Package
    The only airbag kit we have that will fit your 2019 Ford F-250 is the Air Lift LoadLifter 5000 Air Helper Springs part # AL57399 for standard or part # AL88399 for ultimate. The ultimate version has an internal jounce spring which lets you temporarily carry a load with zero air pressure in your springs. The Firestone Ride-Rite Air Helper Springs part # F2600 will not work for you because the airbag installs on the outside of the frame rail which is currently occupied by the factory...

  • Recommended Air Lift Air Spring System and Compressor for 2019 Ford F-450 Dually
    For your 2019 Ford F-450 DRW we have the Air Lift LoadLifter 5000 Air Helper Springs # AL57399, the Loadlifter 5000 # AL88399 with the internal jounce bumpers, and # AL89399 which features the internal bumpers along with stainless steel hardware and lines. Going with the stainless steel option ( # AL89399) is a great idea to ensure a long-lasting system because the lines, hardware, and roll plates will be resistance to rust and corrosion over time. The air springs have a 5,000 pound...

  • AirLift LoadLifter 5000 Rear Axle Air Bag Kits for 2017 Ford F-350

  • What Air Bag System Should I Use on my 2020 Ford F-250 with Factory Prep Package?
    Because you have the factory prep package on your 2020 Ford F-250 you'll need an airbag system that installs under the frame rail as opposed to outside of it, where the factory prep package would interfere with it. For that reason I recommend going with the Air Lift LoadLifter 5000 Air Helper Springs # AL57399 (standard) or the Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88399 (ultimate). The Ultimate version has an internal jounce bumper that will allow you to temporarily...
