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.


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.

Average Customer Rating:  4.6 out of 5 stars   (197 Customer Reviews)

5,000-lb Capacity. These air springs have internal bumpers to provide the adjustable load support of air springs and the comfort and reliability of jounce springs. Durable stainless steel roll plates, air lines, and hardware are rustproof.


The air lift loadlifter 5000 ultimate plus was very easy to install and is a quality product. It works exactly as they said it would. I increase the air pressure when I pull my 22 foot enclosed trailer and let the air pressure down for lesser loads. I am very happy with this unit.


Takes longer than 2 hours to put on vehicle but unit is well built. Stabilizes the truck and trailer and levels it for easier and safer towing my car hauler.

2018 Ford F-150

Install fairly easy. Fit perfectly on my 2018 f150 4x4 no drilling required. Had to cut breakline bracket a little bit. Did not change ride with 10 psi. Looking forward to hauling my rv with it. Used holes on bumper bracket to put air fill points in. Underneath left and right side of bumper mounts.

2017 Ford F-150

Once again, excellent service from etrailer! Good advice from Kyle. Installation went well, following the instructions provided. Also, appreciated the videos. Very pleased with the product. Thanks!


It leaks air. Can find the leak. May be the fault of the installer but he is no longer in business.

This can happen from time to time. If you cant find the leak, I suggest getting a spray bottle with soapy water in it and spay everything down and watch for bubbles. If it is leaking at a connection you can simply remove it and cut the line flush and put it back in. If the bags are leaking you will need to start a warranty on it.
-- Etrailer Expert David B - 08/25/2022


It took me about 4.5 hours to install this kit. About 1.5 of the was collecting the right tools and reading the instructions several times, and checking/double-checking the setup to make sure I got it all correct. The unit works perfectly. Thank you, Ashley for all your assistance, and patience!


I installed this kit about 3 months ago for my 2020 F150. So far it has been money well spent. When heading to our permanent camper 2 hours away, we typically tow the boat and load wood and other supplies in the box. This would drop the rear a lot and we would be shining the overpasses with the headlights.

I am now able to level the truck back out using my M18 inflator. The truck handles the road better when loaded.

When I'm driving the truck empty, I air the bags down to about 5lbs. I do notice the ride is slightly stiffer, but not bad and just a very minor trade off for making the truck much more capable.


Hi George, Yes Sir I’m still liking this system. Truck handles much nicer


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.

Ease of install, product quality

Working out well

2019 Nissan Pathfinder

Easy install and works good.


Received my Air Lift kit in good condition yesterday. Jamie was very knowledgeable and helpful on the phone. The box showed up at y door in two days as promised. I will review the product after I get it installed.


Worked like a charm. Bit of a challenge to install yourself but it’s doable with some patience. I ordered these on [other onince vendor] and one of them exploded on me. The seller had a bogus website and phone number for support so I couldn’t reach them to get it resolved. Ripped it out and shipped it back to [online vendor] to deal with. I will only be buying my truck and trailer stuff from here moving forward.


It is awesome

Review from a similar LoadLifter 5000 Ultimate Plus in Vehicle Suspension

Received my order in less than a week. The directions were lacking a little but no biggie. The first side took me about 2 hrs to install including trimming (I highly recommend using a skill saw with a fine blade to trim if needed). Once I learned what right looked like the second side only took around 30 minutes (including trimming). I have them on my truck for a test run to see how the ride but haven't pulled my trailer yet. Seems like these will be a great purchase and so far I highly recommend.


Review from a similar LoadLifter 5000 Ultimate Plus in Vehicle Suspension

When items were received, the box had several small holes in it, and some of the plastic bags with nuts, bolts and washers were torn open. After going through all of the items, there was a bolt and washer missing. Packaging should be more secure.

Oh shoot, let us make that right! I sent your info over to customer service to get that missing bolt and washer sent out.

  • 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.
