  • Compatible with most gooseneck and 5th-wheel hitches
  • 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

Specs:

  • Load-leveling capacity: up to 5,000 lbs
    • LoadLifter 5000 Ultimate Plus 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

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.


Durable, Rustproof Stainless Steel Components

This LoadLifter 5000 Ultimate Plus air spring kit has rustproof stainless steel components that offer long-lasting durability. These components are the roll plates, braided air lines, and air spring attachment hardware.

Roll plates on Air Lift 5000 Ultimate air spring

The roll plates protect the air springs from damage 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.


The stainless steel air lines are tougher than nylon airlines and last a lot longer. They offer extra protection against damage caused by sharp edges and flying road debris.


And the air spring attachment hardware provides excellent corrosion resistance.


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 Plus 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 truck 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 Plus 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.


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 Plus 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.


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). Any air line excess must be coiled up and secured out of the way, so it won't get damaged. The air line cannot be cut or trimmed. And the valves 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 Plus Rear Axle Air Springs Review

Today you're going to be taking a look at the Airlift LoadLifter 5000 Ultimate Plus line of air helper springs. As you can see, once we add our load to the back of the bed of the truck, we have a significant squat in the back, which is actually going to raise up the front end. That's going to cause a lot of different problems. The back end, we're putting a lot of strain and stress on the suspension. We're not going to have as much travel, as we normally do. Then, on the front, it's actually pulling the front end up, causing a teetering effect, so our headlights are misaligned, our tires are not making as much contact as they should, which is going to diminish our steering and braking.Here's what our airbag looks like, once we have it installed.

It's going to fit in between the frame and the axle, and provide us the support we need, whenever we have a heavy load, like a trailer, fifth wheel, gooseneck, or a heavy load in the bed. Now, with our airbags installed, we actually got our truck back to where it should be with only 40 psi. The back end is not sagging down, as much, and it's being supported a lot better.And on the front, the front is right back where it should be. Our headlights and the front is right back where it should be also. The headlights are going to be aligned and our tires are going to have a good contact on the ground, so we're going to have better steering and braking.Our airbags are designed to replace our factory jounce stop and, as you can see, they are quite a bit bigger, and they're going to provide us a lot more support, rather than the factory jounce stop just preventing it from bottoming out.

Our springs are going to have the best of both worlds though. We're going to have the adjustability of the airbags, but they're also going to have an internal jounce bumper, so it's going to prevent any kind of bottoming out, if we have low or no air in the bags.The internal jounce bumper is going to be urethane, so it's not going to require any kind of maintenance, once we have them installed. The airbag assembly, itself, is going to be a two-ply reinforced rubber, so it's going to have extra durability to it. Our airbags are going to have stainless steel roll plates, as well as, hardware, and the brackets are going to be steel with a black powder coat finish to help resist rust and corrosion.One thing that's going to set our kit apart is that they're going to give us these stainless steel braided lines. These are going to be a lot more durable than the nylon lines that normally come with most airbags.

The nice thing about our airbags is that they are going to be compatible with most goosenecks and fifth wheels, because of how our bracket is going to mount to the frame. Our airbags are designed to support up to 5,000 pounds, and they're going to have an operating air range between five psi and all the way up to 100 psi.Now, keep in mind, these are not designed to increase the payload of your truck. They're really just designed to help support that extra load. Our airbags are going to come with a manual inflation valve. That way, we can inflate our bags easily, wherever we decide to mount it.

Now, it can be Y'ed off into one, so you can connect both bags at the same time, or you can have two separate inflation valves, so you can control side-to-side for those off-center loads.There is an option to where we can adjust the pressure without ever having to get out of the cab. That's going to be with a compressor kit that is sold separately. That will finish up your look at the Airlift LoadLifter 5000 Ultimate Plus line of air helper springs.

Review from a similar Air Lift LoadLifter 5000 Ultimate Plus in Vehicle Suspension


These Airlift 5000 Airbags are EVERYTHING they are advertised to be! Ordered them from etrailer and they were here is 5 days with no shipping charge. Price was the same as I would've paid through that big box website but the personalized service I received from Brenden really made the difference. Thanks Bud! I chose to have my local repair shop install them only because I didn't want to take the time to do it myself. I have a 2016 Ram Crew Cab and I haul a 7' X 16' enclosed cargo trailer. I tried to utilize a weight distributing hitch to take care of the rear sag but there was just not enough ground clearance for the torsion bars. Some suggested airbags instead and WOW...what a difference. I can't believe how much better the truck rides even with no load on the truck. Should have bought these a LONG time ago! 657039

  • Is the Air Lift LoadLifter 5000 Ultimate # AL89399 Compatible with a 2017 F-250 4WD w/ Prep Package
  • The Air Lift LoadLifter 5000 Ultimate # AL89399 that you referenced is confirmed to fit your 2017 Ford F-250 4WD with the 5th wheel prep package. I have confirmed this with my contact at Air Lift. I also recommend installing a compressor system with your air bags. This allows you to increase the psi of your air bags wherever you are. No need to hunt down an air compressor because you are loading up some equipment. We have the Air Lift Load Controller II # AL25592 which is an analog...

  • Air Bag Helper Springs for a 2018 Ford F-350 Dually Diesel 4x4
  • I do have a solution for you but Air Lift does not have an air spring kit that fits the dually models of the 2018 Ford F-350. Instead you can use Firestone kit # F2600. I have linked a video that shows an example installation for you. I also recommend compressor kit # F2097. This will allow you to adjust the air springs from the comfort of the truck cab without having to relay on an external air compressor. I have included a link to a video on the compressor kit as well.

  • Will Viair Air compressor and Tank Work with LoadLifter 5000 Ultimate Plus on 2018 Ford F-250
  • As long as your Viair air compressor and tank is compatible with the 1/4" braided air lines that come with the Air Lift LoadLifter 5000 Ultimate Plus Air Springs # AL89399 then they are compatible and will work well on your 2018 Ford F-250.

  • Rear Suspension Helper Springs for a 2018 Ford F-450 Dually with OEM 5th Wheel Package
  • Air Lift system # AL89399 is designed to fit a 2018 Ford F-450 Super Duty with 4-wheel drive. The upper brackets on this kit mount to the bottom of the frame rails on your truck so it will not interfere with the factory 5th wheel prep package. But the problem is that while this system fits the 2017 model year dually it does NOT fit the 2018 dually. What I recommend is to use a different system that is also compatible with the 5th wheel prep package and that fits dually models. You can...

I really like these particular air springs because they also feature internal bumpers to provide even more load support.

  • The Firestone Ride-Rite Air Helper Springs - Double Convoluted - Rear Axle # F2604 are not the style with the integrated jounce springs but they do install in the same location as the factory jounce. The # F2600 will fit a 2019 F-350 but only the 2WD version. The # F2604 is made only for 4x4 options that are dual rear wheel so it is the correct fit for your truck. Unfortunately we don't have a video of this installation but it is similar to many others that install in the same location....

The difference between these two kits is that the # AL89399 features stainless steel hardware (upper and lower roll plates, air lines, air spring attachment hardware) that will completely resist corrosion over time. Other than this upgraded feature, the two kits are identical. They have a 5,000 pound load leveling capacity,...

  • Yes, you can use a union tee when installing the Air Lift LoadLifter 5000 Ultimate Plus # AL89399 on your 2018 Ford F-350. Just note that this kit uses a stainless steel air line so you will need a tee fitting that has threads. You should be able to acquire one at your local hardware store.

This particular kit is a fit for the 2011-2013 Ford F-450 and there is not a similar system from Firestone that will work on your truck.

  • Air Bag Suspension Enhancement Recommendation for 2019 Ford F-350
  • I recommend the custom-fit Air Lift LoadLifter 5000 part # AL89399 for your 2019 Ford F-350 because it has a 5,000 lb capacity and has an internal jounce bumper in the bag as well which gives you additional support if ever needed. Then the compressor kit I recommend is the Air Lift part # AL25854 as it has a heavy duty compressor that will inflate the bags quickly and comes with a gauge setup that allows you to monitor and inflate/deflate the bags from within the cab of your truck.
