Towing or hauling can drop air pressure fast, and that can shorten air spring life. The Load Controller’s automatic pressure sensor keeps things in check by detecting when pressure dips below the safe level—typically 5 psi—and kicking the compressor on to restore it. If you need a higher minimum, it can also be set to activate at 10 psi. With this automatic safeguard, your air springs stay protected and your ride stays level without constant monitoring.
When weight shifts to the back or you’re carrying a heavy load, the single-path setup inflates or deflates both air springs together so the pressure stays equal. That means the truck stays level front-to-back and rides more predictably. It’s perfect for frequent towing or commercial use where balanced support matters most.
There’s no fumbling with external valves or handheld pumps here. The in-cab analog gauge has a built-in push-button control that lets you watch pressure in real time and make adjustments with a single touch. Inflate or deflate right from your seat and keep your suspension dialed in no matter the load.
The 2-1/8" gauge fits neatly into most custom pillar or dash pods, or you can mount it on your dash with the included stand. It’s small, clean, and easy to read, giving you full control without cluttering your interior. The compact design makes it a natural fit for anyone who wants a professional look and easy access to suspension controls.
This heavy-duty system includes the compressor, gauge, wiring harness, air lines, mounting stand, and hardware—everything needed to set up and go. Designed for consistent use in tough applications, it automatically maintains pressure, keeps your springs healthy, and helps your vehicle hold its normal ride height even under heavy loads.

Thank you for the glowing review Matt! We couldn't do it without customers like you. Have you had a chance to install the bags yet? I am around if you have questions during install :)

So far the compressor that I purchased from e trailer in conjunction with my 7,500 lb airbags is working fine. As I stated in my original review, the only change I would make is to incorporate a delay system into the air compressor activation circuit. When the airbags are inflated at their minimum pressure which is 5 psi, every time the vehicle hits a bump and the suspension extends, the compressor activation circuit senses the in air pressure internally on the airbag and activates itself for a second or so and pumps more air into the bag. After a few bumps and a few of these cycles the airbag ends up with about 12 psi of air pressure in it before the suspension doesnt stretch it out anymore and activate the compressor. Running empty 12 PSI in those bags makes the vehicle run a little stiff. It would be nice if there was a delay, which is what is built into leveling valves on heavy equipment, so that every bump doesnt activate the compressor and increase airbag pressure. Other than that the compressor works fine. As I stated in my last review, I simply installed an off-on switch on the compressor power circuit so that when the airbags were at 5 PSI I could turn the power off and the bags would maintain that pressure.
