Air Lift's LoadLifter 5000 was designed with an exact purpose: to provide full-time, first-class support to your 3/4- or 1-ton pickup, motor home, or commercial truck. With this kit, you get a safer ride and simultaneously protect your vehicle from the strain that comes with hauling massive loads.


Carrying heavy cargo in your truck bed or trailer puts tremendous stress on your vehicle. Your brakes erode faster, your tires wear unevenly, and handling suffers severely. When towing, you might also experience excessive sway, bottoming out, and even improper and unsafe headlight aim. Fortunately, there is a solution to these problems. By pairing your existing suspension with the LoadLifter 5000, you can seriously beef up your suspension, ensure equal load distribution, and give your vehicle the support it desperately needs. Air Lift's LoadLifter 5000 provides up to 5,000 pounds of load-leveling capacity and distributes the weight of your payload to all four wheels. As a result, the stress on your OEM suspension is significantly reduced.


LoadLifter's air bags are adjustable from 5 to 100 psi for precise support, and they can be inflated independently of one another for front-to-rear and side-to-side leveling. They are made of high-quality, two-ply, fabric-reinforced rubber. Most air bags lose air at the ends, where the bag is enclosed with a steel cap, because the steel can rust and corrode over time, creating small holes. 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. Also, LoadLifter 5000 comes with Air Lift's exclusive roll plates, which both protect your air springs and beef up the load capacity of the springs.


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 air in through the inflation valves. A line kit is included with the springs so that you can install the valves (one for each spring) in an easily accessible area - typically they are installed on the bumper. If you want to make the springs even easier to use, you can get a compressor and gauge system (sold separately).


Air Lift kits are designed to keep your vehicle at normal ride height. You can find the normal ride height of your vehicle by unloading it and measuring the distance between the bottom edge of your wheel well and the center of the hub. After you find and record this distance, you can regulate the amount of air that you put into your air springs to maintain normal ride height - even when you are hauling a heavy load. You will need to adjust the air pressure in your air bags according to the size of your load.


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

Super fast shipping good quality produc ts

Air Lift air springs are good and dependable, use them for the last 25 years on three pick-ups always worked great. My complaint would be against the lousy packaging which came with two or three holes and all messed up, luckily all that was missing was one washer.



by:

Installation of the Loadlifter 5000 kit went smoothly, no issues at all. One of the best advantages of having this system on my F-150 is the stabilization it provides when towing our camper. I tow a 6,000 lb camper with an 800 lb hitch weight. I use a weight distribution hitch so the truck and camper ride level, as they should. The difference with the Loadlifter system is that it controls the bounce, providing a much more stable and controlled ride. I highly recommend this air spring kit in conjunction with a weight distribution hitch. When you don't need to added support of the air springs, ie no load, just drop the air pressure down to 5 lbs and you don't know they are there.



by:

just getting done putting my 5000 Justable air springs put them on about three hours I didn’t have any left I did them on the ground so that’s not too bad I’m gonna be sending some pictures along with us so thanks very much and I hope they work



by:

I was really happy with etrailer and would highly recommend them and have to many people this past year. My motor home needed these air bags and I called the manufacturer and gave them my vin number which has always been what was needed for anything I have had the purchase with any of my vehicles. But the person that I delt with said he needed the frame number I said where do I find that and he said I would have to call the manufacturer of the motor home.So I called Newmar and they said to call ford I called ford and never got a call back . I called etrailer and gave them the vin number and two days later I had the parts and installed them the next day . Thank you for having people that know what they are talking about and making my experience a good one .



by:

I installed these air lift bags in a day. It was a lot longer than I thought, but it was in the middle of winter in an unheated shop and only basic hand tools. No hoist, so there were a lot of up and down trips with a creeper. Very good installation manual which made the process easy. Very happy with the purchase.



by:

It was exactly as described and advertised. Works perfectly on my 2019 Ford F150. It took me longer than expected to install because of the fridge was just filled by my perfect wife who knew I was going to be installing the kit. The kit helps me with towing my travel trailer. My truck looks great jacked up rolling around town but I took it back down to the recommended 5lbs.



by:

I installed these on a 2004 Ram 2500. I have towed an 11k fifth wheel approximately 10,000 miles with them and couldn’t be happier. The hardest part was figuring out where to put the airlines. I decided to run them through the existing frame holes and drill out the top license plate screws to give them a stealthy look with easy access to fill. Install didn’t take more than 2 hours with air tools.



by:

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.



by:

The hitch and box arrived in exceiient conditon. I have yet to take the rig for a good test drive. I took it for a short drive but need more time with ot to fully appreciate its capabilities. The installation was a breeze. Fitment was perfect.



by:

Installed thes a year ago. I use them to pull my 35 foot fifth wheel camper. They are fantastic I recently added the wireless remote air compressor kit. I really love that!



by:

The product was exactly as advertised. The installation instructions and video were easy to follow.



by:

I FIT THESE ON A NISSAN NV 3500. IT TOOK SOME WELDING ( THERE IS NOT A MODEL FOR THESE BUT MY MECHANIC KNEW HE COULD MAKE IT FIT). THEY ARE GREAT!! YOU CANT OVER LOAD THE TRUCK I KEEP IT AT 70 PSI. I ALSO FITTED AN ELECTRIC COMPRESSOR AND AN ADJUSTABLE 1/4 INCH REGULATOR AND DONT NEED ANY ADJUSTMENT.



by:

First, looking at the website was pretty easy to navigate. Ordered product and confirmed delivery email sent that evening. Received two days later. Box a little damaged, but that was on FEDEX. However everything inside in tact and instructions were simple to follow.

The product, I wish I would have gotten these years ago. Makes the unloaded ride much better and not so “horse bucking” that I was used to. I usually loaded the back with 150 lbs of sand. No longer, rides smooth. Haven’t had a loaded test yet but looking forward to it.



by:

We just installed this last night on our truck. The instructions are easy to fallow. We will get our new 5th wheel next weekend so we will see then if they hold up. We love etrailer.com excellent customer service and fast shipping. Chris W thank you so much for taking care of our order so quick!!! We are working so hard on getting everything installed before we get our new 5th wheel!!! Your Amazing!!



by:

Excellent. Air Bag kit came in 2 days. Installed today on a 2022 Ford F150 Platinum 4X4 with rear axle mounted headlight leveling arm. Installed in a couple hours. Looks great and works excellent!



by:

Kit is well designed... However; Its a Premium priced kit with cheap hardware, steel nuts and bolts used instead of stainless - they will rust quickly, air fittings are cheap and air hose is obviously the cheapest they could find - very inconsistent in diameter and doesn't seal well in the fittings.



by:

The air bags fit perfectly and the directions were easy to follow. I am genuinely impressed with the customer service. I called with a concern for the shipping, and had great assistance from the representatives I spoke with. Well done, and thank you.



by:

Air Lift Loadmaster kit was fairly easy to install and definitely made a difference! It did take roughly 4-5 hours by myself but that includes prep, ABS and emergency brake relocation, Schrader valve installation and leak check. My only advice would be to give tech tips like a 10mm deepwell socket to remove the jounce bumper on late model Chevrolets/GMC's. I spent 30 minutes trying to figure that one out alone! So far I'm really impressed with the outcome! Thanks!



by:

This is my second truck I've installed the airlift system on. The installation went smooth, just like before; after watching the installation video it took maybe a couple hours. I had them aired up and hitched the truck to the fifth wheel, and it made a big difference with leveling the hitch load. I'm very pleased with them.



by:

It seems like the design was not re-engineered for the current (2023) model ford f150. The directions for brackets for brake lines and wire harness are not the same as in the instructions. Also the I bolt on the drivers side does not clear the brake line. I had to disconnect the brake line all along the groans to make it fit. Now the brake lines are not mounted the way they’re supposed to be. I hope I don’t have a problem with that.



by:

This whole system was a Rube Goldberg special, engineered and installed by myself (a retired old DIY geezer). Use it for load assist when I put our Cab-over camper(3000#) on or haul any other heavy load. The Air Bags do the job and the installation instructions were pretty good (better than most). My only complaint is that the system doesn't hold the pressure over night. That is probably a feature of the plumbing and fittings; could be the ones on the top of the bags or another back up the line to the tank & compressor.
Overall I'm pleased with your product and service and that's why when I'm in need I deal with Etrailer.



by:

The load lifter installation went fairly easy. Using an oscillating cutter worked well for cutting the bracket on the driver's side. I would recommend watching the video so you can relate with the instructions. The load lifter itself is working as advertised. My trailer pulls much better now.

  • Recommended Air Helper Springs for a Class C Motorhome on 2001 Ford E-450 Chassis
    I have just what you need to add airbags to a 2001 Ford E-450 Chassis (Class C Motorhome), the Air Lift LoadLifter 5000 Air Helper Springs part # AL57242 unless you have supply lines on the outside of the frame then use part # AL57131. These kits are both no-drill options which is rather rare for a motorhome.

  • Air Lift Suspension Enhancement Kit that Fits 2020Thor Fourwinds 31E
    Yes the Air Lift LoadLifter 5000 # AL57242 is a confirmed fit for your 2020 Thor Fourwinds 31E motorhome! For a compressor kit then the heavy duty part # AL25854 will work great to make inflating the bags and maintaining them easier. The compressor will inflate faster than standard compressors and the gauge inside the vehicle will allow you to monitor and inflate them from inside the vehicle.

  • Replacement Air Lift Air Bag for Kit 57242 on 1997 Ford E-450 Motorhome
    Thanks for the pictures! The 5814 number you found actually has to do with the construction of the air bag and isn't really the part number for the bag, however since you sent in the picture of the instructions that shows you have the Kit # AL57242, this means that the correct replacement air bag is part # AL50251. The photo for this air bag (as of May 2020) is a generic one. The actual air bag will look closer to the part # AL50201 that you referenced.

    While we don't have any air spring kits that fit your 2020 Winnebago Minnie travel trailer we do have Timbren kits like the # TTRA1032 which can be used on trailer suspension to provide addition suspension support. These do provide even support for both sides of the axle though and there isn't a way to provide more support to one side than the other.

Air bags like the Air Lift LoadLifter 5000 Air Helper Springs # AL57242 will also fit and would be helpful but are not the best way to stop sway on a motorhome.
