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.

I've owned 3/4 ton trucks since 1981 and regret buying a light duty truck when I'm hauling and towing. A close call with an overloaded trailer and the State Police forced me to upgrade my suspension. My search started with overload springs and bump stops but the negatives (for me) was everyday ride quality with springs and remaining load sag with bump stops. I considered a weight distribution hitch but I'm pulling different trailers and hauling firewood in the bed. Everything mentioned above narrowed it down to air springs so a lot of product comparisons were made and questions were asked to truck mechanics and owners. My decision to purchase this kit was because of the braided stainless steel air lines. Their threaded connection eliminates air leaks and they're much more durable than thin plastic lines when I'm in the woods cutting firewood. These Air Lift bags were installed on a 2011 Silverado 1500 with the help of a friend and his high lift and it took us about 2 1/2 hours. There's a front leveling kit in this truck and with the air bag pressure at 8 lbs., the hitch level rose 3/4 inch and the ride quality (when empty) is the same as before. When I pulled an 8' x 16' enclosed trailer and 1000 motorcycle last week, the air bags pressure was increased to 30 lbs. and it pulled perfectly. The truck was very smooth at speeds up to 80 mph and there's no sway in the turns at all. My negatives are: : Without an electric air pump, it's kind of a pain to add air manually. A small (2 gal.) portable tank that I can fit under the back seat will solve that. : The mounting hardware in this kit was not stainless steel. : etrailer does not have a "T" connector for these air lines. They sent two different fittings - one was part #AL21838 for plastic lines and the second fitting (from Air Lift) only had one threaded connector. After waiting 9 days for the second fitting, I found a brass fitting locally for $4. 676721

The bags work great with the wireless compressor. I had my right rear stainless braided airline burst and need to get a replacement. Besides that they work awesome! Just ordered a new F-450 and will definitely be putting a set on it as well. Let me know where I need to call to get a replacement. Thanks 777681

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

After a year of use it still works great. If I had any complaints it’s that the heat shield has a rattle at idle, but I can only hear it when I’m outside the truck. I look at it like a nature of the beast kind of thing. 798461

Every item arrived in perfect conditions very easy instructions to follow the only thing is using this adapters ( AL52460 ) the ABS line cannot be connected like shown on the pictures. But without any question so far no complaints. 801209

Review from a similar LoadLifter 5000 Ultimate Plus in Vehicle Suspension


Super easy installation but if you get the stainless steel lines, it won’t connect to the Air Lift compressor. Also, tighten the lines at the bag before tightening the upper brackets. There will be no room afterwards. The instructions do not tell you this. Otherwise, the bags are great. Don’t let a couple minor instruction issues deter you. ETrailer is the place to buy all your truck needs. 790546

Hard to rate the bags themselves as I haven't used them pulling the fifth wheel yet. I think they are going to be great. As for installation, it was a big pain in the *^$. Airlift needs to try and do an install following their instructions( or lack of ). Good thing I have extra nuts and washers around, I needed some. That engineer is probably still laughing, and I still cuss when I look at them, it could have been a lot easier with better direction. 789913

Ask the Experts about this Air Lift Vehicle Suspension

  • Best Rear Suspension Upgrade for a 2020 Ford F-150
    My favorite upgrade for rear suspension systems on the 2020 Ford F-150 are air bags. These help get your truck back to factory ride height and take a lot of pressure off of that rear suspension system. By taking that pressure off of it you are dramatically extending the life of the system. Airbags will also give you full control with changing loads. The heavier the load the more pressure you want in the system, the lighter the load the lower the pressure. There are a couple of types...

    For your 2018 Ford F-150 4WD that has a 5th wheel hitch installed the air bag kit I recommend is the AirLift LoadLifter 5000 # AL89385. This is one of the few kits that will work great along with your 5th wheel setup. You can refer to the linked installation video showing 2017 F-150 to see the process. The written instructions are also linked for you. Many air bag owners that have 5th wheels end up using a compressor kit. Compared to pulling off the road to inflate/deflate the bags...

    The best solution for you will depend on how you usually use your truck. If the sag you experience is caused by the slide in camper only, or may also when you to a gooseneck or 5th wheel camper, then a Timbren Suspension Enhancement System like # TFR1504E would be a great choice. The Timbren system won't impact your suspension performance until the rear suspension compresses by around an inch or so. This means no air lines to mess with, no ruptured bags, no guesswork.

  • Recommended Suspension Enhancement Products for 2020 Ford F150 4X4
    If you'll be towing a consistent weight, a system like the Timbren # TFR1504E would be an outstanding choice. The Aeon springs have several advantages over air bag systems if you don't need the adjustability provided by an air system. The springs get progressively stiffer as more weight is added, and there's no worry of anything leaking or puncturing. If the loads you'll be towing or hauling will vary, you'll want the adjustability provided by an air bag system. The LoadLifter 5000...

  • Why are Some Air Bag Suspension Kits for 2015 Ford F-150 Compatible w In-Bed Hitch and Some Aren't
    Air bag kits attach to to the truck's frame in roughly the same area as in-bed hitches like gooseneck and fifth wheel rail kits which is why there can sometimes be interference. So the Firestone kit part # F2582 that you referenced is not compatible due to it's bracket design but we do have the Air Lift LoadLifter kit part # AL89385 which is compatible with in-bed hitches. The compatible kits basically have a bracket design that won't interfere with the rail kits.
