Automatic Pressure Sensor

Low air pressure is the leading cause of air spring failure. To avoid this, you must either regularly monitor your air springs or find a device that will do that for you. Air Lift's Load Controller does just that. If the air pressure in your air springs falls below the minimum safe level of 5 psi, the system's low-pressure sensor detects the decrease in air pressure. Then the compressor activates automatically to adjust pressure as needed. If your particular application requires you to maintain a minimum of 10 psi in your air springs, you can also set the system to activate when the air pressure is below 10 psi.

Stylish, Compact Gauge

Air Lift gauge for controlling air spring pressure

Load Controller comes equipped with a sleek-looking, compact gauge that provides detailed monitoring of your air pressure. The space-saving gauge can be mounted in whichever way works best for you. Just attach it to your dash using the included mounting pod. Or for a from-the-factory look, install the gauge using any custom pillar or dash pod (not included) with a 2-1/8 inch pre-cut hole.

Face of gauge with push-button controls

Built into the face of this gauge is a one-touch, push-button control that allows you to inflate or deflate your air springs while monitoring their psi.

Dual-Path System

Load Controller is made to help support your air springs as they take on weighty loads, and it's great for heavy-duty and commercial applications. The dual-path controller lets you adjust two air springs independently of each other for better control. So aside from leveling your vehicle front to back, you can also level it side to side by putting a different amount of air into each spring. This allows you to even out an off-center load.

Alternatively, you can use the Load Controller to adjust and monitor two pairs of air springs independently. Using this configuration, you can inflate your front pair of springs to a different pressure than your rear springs. This will allow you to level your vehicle front to back.

Determining Ride Height

Load Controller will help 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 send to your air springs to maintain normal ride height - even when you are hauling a heavy load.

etrailer customer service is the best! And they have quality products. I have purchased towing systems from etrailer in the past and always found them to be of high quality. They deliver their products very quickly.

This latest purchase of air helper springs was damaged in shipment. When it arrived, the box was torn, covered in tape, and 3 of the 4 large steel brackets were missing. Roger of etrailer was extremely helpful, and quickly sent me replacement brackets. These just arrived today (and the package was intact!).

It will take me a while to get the system installed on my truck, and I will write another review when I have the system working.



The airbag suspension and controller system work great. I have a 2017 RAM 3500 dually and I built the control system into the dash. There are cubbies under the floor in the back seat and I mounted the compressor and valves into one. The system keeps the truck level and stable even with our heavy camper loaded. I would definitely recommend this system if your truck needs a little extra spring in its step.


Overall the system works very well. Installation was a breeze and everything needed was included. I like being able to adjust each spring individually and how easy the dual gauge is easy to read.

Unfortunately, my original dual gauge leaked air internally and I had to order a replacement because it would bleed off overnight. I went with a replacement that is the same as the original because I like how it functions better than the other options on the market. I hope that the new one does not begin leaking as well.



UPDATE! The replacement gauge has been working flawlessly. I’m super pleased with this setup! It keeps me level and stable while pulling my 5th wheel.

@Rusty We're glad it's working well for you!


The Air Lift controller works as promised. The folks at etrailer were great at getting the unit to me when they were in short supply.



The air compressor is still working great over a year later.


I prefer speaking with someone when I order parts for my truck so when I say that ordering was effortless, smooth and easy then it was. Also delivery was on point.


We purchased an AirLift to add to our 2015 Ford F-250 4X4 when we purchased a new (to us) Montana 3160 Legacy 5th wheel trailer. The air bag system helped with the rear droop that we were experiencing and helped level out our ride. While towing now, we are experiencing a much smoother ride. This package was well worth the investment.



Great, no issues, product works well.


Shipped and received quickly, pretty easy install and my 2500 no longer squats under my 24k gooseneck


Excellent product! The instructions to DIY are self explanatory and easy to understand. You just have to have common sense and the want to. My passenger side air bag was leaking by and I messaged Air Lift's warranty department. Within two days they responded and sent out a new bag without any questions asked. As long as you have proof of purchase and explain your problem in depth and troubleshooting you should have no problems.


Works great


It's a nice kit and works as advertised. For heavy hauling an airbag kit is really nice. I've installed several now for friends. My f350 srw longbed had drive line vibration off the line when towing heavy loads. With the air bag kit I can maintain the normal drive line angle and that got rid of the nasty vibration.


E trailer was great fast shipping. The Kit was fairly easy, I installed it on f250 2012 4x4. My Ford has outfitter switches on it and it took long to reseach where outfitter leads and colors to the switches than it did to install. The Air lift controller lifts and lowers fairly quickly . I give this product and the company 5 stars.


Added the compressor system to Firestone Ride-Rite airbags on a small RV with a 2018 Ford Transit 350HD chassis. System was easy to mount and works great. Hardest part was deciding where to mount the gauge.


The customer service was not good, the airbags that I ordered were showing in stock and when I ordered them my order shipped minus the bags. Called to find out the status of them and nobody could give me an answer, they had a bad attitude when I asked them the status and assured me they would call me back. 2 weeks went by without a response, I called back again with the same result, they told me that they couldn’t get ahold of the manufacturer. I hung up the phone and called the manufacturer myself and got a status update that the bags wouldn’t be in stock for months. I had to cancel my order and reorder the smaller bags, they assured me that they would ship immediately as they were in stock, took 2 additional weeks to get them. Absolutely horrible experience…


My purchasing process was perfect. Emily was so helpful and very knowledgeable about everything. It was my pleasure dealing with her. And I'll spread the good word. Kudos Emily


Excellent service.. Part was shipped same day and received 2 days later.. Part was as ordered and fit perfectly. Directions were easy to follow and clearly stated.. The folks at etrailer are great to work with and I will be back... Thanks Vern..


Thanks great service


Delivered as promised thanks


The vendor never shipped it and I ended up canceling the order.


Very fast delivery







Fast Delivery. Good product.

  • Can Air Lift Load Controller Compressor Kit Control Front Axle Bags Alone
    Yes, since the Air Lift Load Controller Compressor System for Air Helper Springs # AL25856 that you referenced is dual path you can use it to just control a front air bag set for time being and then later down the road have it control a rear set as well.

  • Is an Air Tank Required with a Compressor System to Inflate Air Bags on a 2012 Dodge Ram
    No, you do not have to have an air tank with a compressor system in order to fill the air bag helper springs on your 2012 Dodge Ram. A system such as # AL25856 would work well for filling the air bags. I have included a link to the compressor options both with and without air tanks.

  • Custom Gauge Pillar for the Gauge for Air Lift Suspension on a 2006 Ford F-350 King Ranch
    The gauge size in Air Lift kits like # AL25856 is designed to fit most custom pillar pods or dash mounts but they do not offer custom pillars or pods. The kits do come with a small pad the gauge fits in that can be mounted on the dash. For a 2006 Ford F-350 you can use Air Lift system # AL57212. A company called AutoMeter makes some custom gauge pillars that might work for you.

    In order for an air helper spring like what's offered by the Air Lift # AL88216 Load Lifter 5000 system to work effectively, you'll want to be sure that the existing leaf spring suspension on your truck isn't worn or damaged. A system like # AL88216 won't provide lift over and above the unloaded ride height, but it will provide up to 5000 lbs of extra support to a factory suspension that's in good repair.

    I recommend going with the Air Lift LoadLifter 5000 # AL88288 for your 2019 GMC Sierra 1500. Since you will be using this for 5th wheel towing you'll have to do a little drilling and the only other part of fitment that is worth noting is that this isn't compatible with your truck if you have that Adaptive Ride Control. I also recommend installing an air compressor kit like the Air Lift # AL25856 so that you can monitor and adjust your air bag kit while on the go. This compressor system...
