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 3/4- or 1-ton pickup, motor home, or commercial 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 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 (1 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.

The airlift bags are really nice quality! I would say they could go into a little more detail in the instructions for putting the brackets together for the diy people.

Ram 2500

I’ve been using these for about a year now on a 2500 HD pulling a 24’ enclosed trailer. They work great, truck handles much better than it did without bags.


The staff at etrailer was great. They verified that this product would fit my application even though there is a fifth wheel rail bracket involved.

Also I ordered multiple products and one of the products was delayed. The offered to split the order so I could receive the air bags sooner, which I needed because I have an appointment to have them installed


A great product. Well built out of rugged materials. Super easy to put in. I would recommend them to anyone. I got this brand because my father put some in his truck when he was towing his 5th wheel camper. Great costume service.


I recieved the wrong item, but they where quick to get the right item shipped to me. That means more then anything. These things happen, custoomer service is what matters. Thank you Daniel B and Tammie P for everything you do to make things right.



I have bought a few items from etrailer and I can depend on any help I might need. The air lift 5000 is a great product and is easy to install. I have use other air lift systems on my other vehicle. The air lift system is a better product for the price. Thank you etrailer.


Great product. Easy to install and works as it should

2016 GMC Sierra 2500

Watched the video, took about an hour to do the installation myself. I added this product to level out truck when hauling my fifth wheel camper. Overall great craftsmanship on this product, easy installation. I just couldn’t drill holes in my new bumper for the valve stems, so I add a piece of aluminum angle iron, drilled two 5/16 holes and added two self tapping screws to the hitch, turned out well.


Took me about an hour to install on my 2018 GMC 3500 HD DRW. Instructions were clear and in English. Works flawlessly.

It would be nice however, if the manufacturer would take the time to completely assemble the springs before they ship them. It took me 30 minutes to put them together. If the factory assembled them, installation would take 30 minutes and be done.

2012 Chevrolet Silverado

Great product as always. Keep using UPS SHIPPING AND YOU'LL KEEP MY BUSINESS.

2016 Chevrolet Silverado 2500

This item was shipped and received on time. The install went fairly well. Since I had a B&W hitch in the truck already I had to drill two 5/16 holes in the frame. I would recommend this item



The air fittings on the air bags leak, I changed them out but I think after time they will leak again. But the unit works great I would recommend


The airbag system lifted my truck back to a normal ride height while hauling my 4000 lb truck camper. It allows my suspension to respond to the road without bottoming out. Stabilizes excess sway on corners and during high wind events.

2011 Chevrolet Silverado

Just finished installing and the one issue was the lower bracket.I believe it could be installed either way,there is a cutout and that part was not easily shown in the pictures. But I got it. Took me about an hour and a half each side.removing the brake cables took the longest because of that and not much room and I didn't have a 13 mms open end wrench. The first thing you must do is remove jounce bumper. They say pry it out with 2 screwdrivers. After 15minutes of prying i have up and got a large (4 inch) channel lock pump pliers and gave it a twist . Out in seconds. Works so much better and no skun knuckles. Looking forward to use ing it soon on my truck camper. It was bottom ing the bounce bumper all the time.


This is a good brand of air springs and I'm satisfied with the quality. When I drilled the holes for the upper bracket to use the (4) supplied self-tapping bolts, the first two twisted off at the head. I feel that the bolts were made of metal too soft for the application. I ended up using the U-bolts for the rear but the gooseneck plate wouldn't allow them in the front. Had to grind the bolts off and redrill the holes. Figured 1/32 larger would make it easier to tap and still tighten to specs. Got them installed and they are working fine.


This product made a world of difference on my Chevy 2500HD. My slide in camper is just below weight limit and was not riding comfortably. I installed them myself. Super pleased with the result.

2015 Chevrolet Silverado 3500

Instructions were very clear. I made photo copies of the two pages with the overall drawing and the material list so I did not have to page back and forth. I have a fifth wheel plate in my truck which required the drilling method of attachment for the upper bracket. It would be nice to have some suggestions to make that process simpler.


The air bag I purchased was to replace one that leaked. The replacement bag STILL did not hold air. Am tired of constantly having to keep this bag aired up.

You mentioned that the replacement spring also is leaking air. I wanted to ask you if you have completed the soapy water test to verify where the leak is coming from just in case that it is not the spring.



The air bag is leaking!!

I apologize as I do not have a solution for you other than to reach out to Airlift for a replacement. I can also offer a different system for your truck. I would just need to know if it is a 2 or 4 wheel drive.

2018 GMC Sierra 2500

I got these air bags on a recommendation. I am getting a fifth wheel trailer and wanted to go down the road with a little security knowing my suspension would handle it. I ordered these and installed them myself. All the parts were there and the instructions were perfect. my biggest decision was where to put the air line. I decided to put them on either side of the license plate. I haven't had a load yet but I am sure they will work fine.


This was the first time that I purchased from etrailer. The staff were wonderful to work with. They know the products that they sell and were very helpful. The order was delivered before the estimated delivery date.

I will l be buying from them again!

2017 GMC Sierra 3500

Another purchase delivered reasonably quick and completely undamaged.

While I initially thought the package had gotten sidetracked or delayed during shipping I was just too impatient. I wasn’t fully considering the shipping rush with Christmas returns and gift card purchased. The initial packaging and shipping was very rapid, like normal, but I then got hung up on the fact that the tracking information showed it left Missouri and then no updates for 5-6 days. So I emailed to get an update, and a response quickly arrived showing me that it had just arrived in the L.A. area. The order ended up arriving on time, just like they said it would. Once again, great selection and great service!

2013 Chevrolet Silverado

Fast shipping!

2011 GMC Sierra

I order a lot of parts from E trailer and they come through every time for me


Very easy to install put on 2500 Chevy duermax and it does every thing it said it would do.would buy this item again if had to.


Great service. Super fast shipping. Love etrailer!

2015 Chevrolet Silverado 2500

Parts were out of stock, but I received a email right away with a date they would be shipped by and they arrived sooner. Great company to work with. I will continue to use Etrailer and highly recommend them

2011 Chevrolet Silverado

Great product and having the videos helped the instillation go a lot faster!
