If you're still airing up manually or using a basic setup, this kit changes everything. Get full control from the cab with in-dash switches, a digital gauge, and a full onboard air system that levels loads and adapts on the fly.
Separate dash-mounted switches give you true side-to-side control over your air springs. Fine-tune each side independently to level out uneven loads or compensate for shifting cargo without ever leaving your seat.
Onboard air doesn't stop at air bags. The HP325 Series compressor and 1/2-gallon tank give you pressurized air wherever you go, whether you're airing up tires after a rocky trail, clearing off dusty gear before packing up, or running air tools for quick repairs on the jobsite. The included 25-foot curly hose reaches around your setup with room to spare so you can handle roadside fixes without hauling extra equipment. It's one of those upgrades that quietly earns its keep.
This kit gives you everything you need to run onboard air: a chrome HP325 compressor, 1/2-gallon steel tank, electric solenoids, digital gauge, and all required wiring and fittings. It's a complete plug-and-play setup with no guesswork required.
The solenoid block can be expanded to control more accessories later—like air lockers, train horns, or onboard tools. Whether you're setting up your first air system or upgrading from a manual kit, this platform is ready to grow with your build.

Hi everyone. Steve here with etrailer. Today we're looking at our pack brake premium in cab air control kit with included compressor, tank and digital gauge. Now this kit's gonna give you what's considered an independent fill option. So if you're looking for simultaneous filling, meaning both bags at the same time evenly, you need to look at kit number HP 1 0 2 7 4 sold separately. So again, folks, today we're looking at the independent fill or side to side individually.
So that's what's great about this kit. The cylinder block can also be expanded in the future. So if you need to control other accessories in life later on, like air lockers, train horns, OnVar tools, those kind of things, you have that capability to expand in the future. Now, this also gives you an in cab control module that's gonna make it really easy to inflate or deflate those air springs independently. Depending on which one you want side to side, that's the one you would select and go up or down.
Now this is gonna light up visibly for you whenever it's all powered up and installed. And of course you get the onboard air compressor. Very simple to use. 12 volt operation. And of course the air tank is included as well.
It's a half gallon tank and basically this whole kit's rated for zero to 220 PSI with increasements of one PSI. So as you can see, there's lots of different components included here. You're gonna get solenoid valves, T's, everything you need, pressure regulators, sensors, cutting tool for the air line, wire loom to protect the wires and everything, all your fittings. You even get a little accessory kit included. I didn't have space to put all this out on the table.
You get the coiled up air line and then you get all your different attachments for inflating balls, tires, those kind of things. And adapters as well if you wanna hook up air tools and those kind of things. So you get a lot with this kit, folks. It really does come with a lot of different neat things. And again, it uses a premium electronic control valve. So using dual 12 volt solenoids, it's gonna provide that fast, reliable inflation or deflation. So again, with this kit, you're able to lift up and even out as needed. So maybe you have, I don't know, an embed camper or something that's heavier on one side versus the other. You can now individually inflate that one bag to bring everything up level and give you the best possible ride with that system. So once again, folks, this is the independent fill. If you're looking for that simultaneous fill kit, that number again sold separately is HP 1 0 2 7 4. Folks, I'm Steven with etrailer. Thanks for watching. Reach out if you have questions about this kit or anything else and have a great day.
