When the back end starts to sag under a trailer or a load that’s heavier on one side, the Load Controller’s dual path design keeps things level. You can run two air springs independently from the in-cab controller to balance side-to-side or front-to-back. The one-touch push-button on the gauge makes it easy to inflate or deflate each spring until your stance feels right. With up to 120 PSI of heavy-duty output, it’s built for serious hauling and frequent towing.
Air springs lose life fast if the pressure drops too low. This system watches for that and takes care of it for you. The automatic low-pressure sensor detects when pressure dips below your set safe level—typically 5 psi, adjustable to 10 psi—and kicks the compressor on automatically to bring it back up. You don’t have to think about it or risk running too low; the system maintains the minimum pressure needed to keep the springs healthy and working right.
Instead of crawling under the truck or dragging out a hose, you can fine-tune your air pressure from the driver’s seat. The small, stylish gauge mounts cleanly on your dash using the included stand and fits standard 2-1/8" pillar or dash pods if you want a custom look. The simple one-touch control on the face lets you add or release air instantly while watching the PSI change in real time.
Whether you’re towing, hauling, or just loaded up with gear, it’s easy to keep your normal ride height. Once you’ve measured your unloaded ride height, just dial in the pressure until your springs hold that same height under load. The compressor will automatically maintain it, keeping your handling and comfort consistent no matter what you’re carrying.
Everything you need comes in the box—compressor, in-cab gauge, wiring harness, air lines, gauge stand, and hardware. Designed for heavy-duty and commercial use, the Load Controller system is compatible with any brand of air springs. It’s a reliable setup for anyone who hauls often and wants dependable, automatic control over their suspension every time they hit the road.

The vendor never shipped it and I ended up canceling the order.
faut shopping thanks
Fast delivery, easy ordering
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.
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..
Shipped and received quickly, pretty easy install and my 2500 no longer squats under my 24k gooseneck
I wish it worked better in the winter but in the summer, it’s amazing
just what I needed to adjust either the front or the back. suspensions.
Quick and easy install!! Fast delivery
Had some custom fitting for my particular 5th wheel hitch but preferred the air bags to mount directly above the springs instead of inside the springs on the axle.
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…
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.
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.
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.
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.
Works as advertised. No problems after a yeaR OF USE.
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.
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.

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.
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.
Installation fairly easy, works great. Has not been back for any repairs or adjustments.
The air lift kit works very well and the team at E-trailer helper me select the correct kit. I've had no issues at all with it and am 100% satisfied.
E trailer was great. Work all the way though with me to get the correct parts.
The air tubing is not long enough, had to order more. Didn't come with connection for air bags, had to buys some. Cutting and splicing wiring to make fit.
I found it very difficult to mount the air gauge controller inside the cab there is no good place for it. Also routing the air lines through the firewall was not any fun. I wish I would’ve went with the remote control version. I did like the option of being able to level the truck up with the dual controller.
