Heavy trailer, camper, or bed loads can leave your truck squatting and less controlled. These air springs add up to 5,000 lbs of leveling support to reduce sag, sway, and bottoming, while internal jounces let you run 0 psi unloaded.
When trailer weight, a slide-in camper, or a heavy bed load settles your truck onto its rear suspension, squat and extra body movement can make the truck feel less controlled. The two adjustable rear air springs add supplemental support to help reduce sag, sway, and bottoming while letting you tune the suspension to the weight you're carrying. With up to 5,000 lbs of load-leveling capacity, you can add only the pressure the load calls for instead of treating maximum pressure as the default. Your truck can sit closer to level and remain more controlled while carrying or towing substantial weight.
A truck that tows one day and runs empty the next doesn't need the same rear-suspension support all the time. Internal jounce bumpers let you add air when your trailer, camper, or cargo is aboard, then reduce the air springs to 0 psi once that load comes off. Those internal jounces also protect the air springs against bottoming when suspension travel is used up. You get the support your truck needs under weight without having to keep air in the bags simply to protect them when you're driving empty.
Suspension hardware lives where road spray, dirt, and weather reach it, so material choices matter underneath your truck. This kit uses braided stainless steel air lines along with stainless steel fittings, Schrader valves, roll plates, and mounting hardware to add corrosion resistance throughout key parts of the system. That extra durability is focused where it matters, helping the hardware you rely on for load support and pressure adjustment stand up to the environment beneath a working truck.
You'll start by measuring your truck's stock ride height and checking the available space between the axle and frame before removing the factory jounce bumper assemblies. The air spring assemblies mount between the frame and axle using the existing jounce-bumper mounting hardware up top and adjustable brackets around the axle and leaf springs below, with careful alignment and brake-line clearance checked before everything is torqued down. Once the springs are secured, you'll install the passenger-side exhaust heat shields, then route the braided stainless steel air lines with enough clearance and slack for suspension movement before mounting the Schrader valves where they're easy to reach. Adding air bags is a job experienced DIYers can handle, but if you would rather leave it to a professional, we can help you find an installer near you.
The included Schrader valves give you everything you need to adjust the air springs manually, but pulling out an external compressor can get old if your towing or hauling setup changes frequently. You can add a Pacbrake Bravo Wireless Air Control Kit (sold separately) to adjust pressure from your phone, check live pressure, and save presets for loads you come back to regularly. Also, you'll be able to choose between filling both air springs together or controlling them independently when the load isn't even side to side. It's an optional upgrade, but one that makes the adjustable part of an air-spring system much easier to use regularly. And it's not the only solution available. There are a variety of compressor options from Pacbrake that might be the perfect fit for your setup.

Hi, everyone, Steven here with etrailer. Today, we're taking a look together at the PacBrake Alpha HD Pro Airbag Suspension Kit with included internal jounces for the rear of your vehicle and it features the stainless steel hardware upgrade package. Now, folks, these are rated at 5,000 pounds capacity and they do fit the 2017 through '26 Ford F-250, 350, and 450 Super Dutys. And this is gonna be a custom kit, so make sure you're checking that fit guide over at etrailer.com to be sure you're getting the right parts the very first time. And if you don't wanna tackle the installation yourself, we also have a dealer locator tool where you can type in your zip code and we can help find somebody in your area that can do the installation as well. Now, taking a closer look at these, let me step out of the way so you can see them better.
I've kind of preassembled these today, just so you can kind of see a generalized picture of what they're gonna look like, potentially, when they're installed. Keep in mind this is all just kind of loosely on the table. So make sure you're double checking with the instructions, as far as the directions of everything and the placements and whatnot. Now, as I mentioned before, these do include an internal jounce. And what that looks like, here on my cutaway, this is a generic cutaway picture from PacBrake.
You can see that kind of yellow rubber jounce inside of there, that's integrated inside of there and that's gonna work great, especially if you're running these at zero PSI when they're unloaded. It's gonna keep everything safe and protected and give you a little bit more cushion inside of there as well. And the other thing I'm gonna throw up here on the screen is a picture of the complete kit. So obviously, like I've mentioned before, I've got these preassembled on the table today. You're gonna get the stainless steel upgraded kit included here.
So you're gonna have the stainless steel, those round plates that go over and beneath the airbags, you're gonna get the stainless steel braided airlines and stainless steel hardware. Now, the way they've got these kitted together is you're probably gonna get a couple extra bolts and nuts because the stainless steel upgrade kit just kinda puts everything needed for the different airbags that they carry. So keep in mind, again, follow those instructions, make sure that you're using the correct hardware for your specific application. And again, if you have some hardware left over, don't freak out. It's gonna be normal.
And again, you might get some extra plates that are not stainless steel as well that come in there and those are for the basic kits that are out there. So again, just make sure you're following the instructions. And again, reach out to us if you have any questions when you get these or anything. And as you probably already know, airbags are gonna be great for keeping your vehicle back to your level OE ride height. So if you're having problems with squat and having problems with traction control, potentially, because the back end's getting weighted down, these can help alleviate that and these will lift up that back end back to the stock height, thus putting pressure back onto the front axle and giving you that traction back, keeping those headlights pointed at a safe, correct angle and those kind of things as well. And again, folks, these are rated for 5,000 pound capacity. And the stainless steel upgrade just makes it really good, as far as durability and longevity as well. Well, folks, that's gonna wrap up our quick look together at the PacBrake Stainless Steel Airbag Suspension Kit. I'm Steven, thanks for watching.

Did not fit my truck 2026 Silverado 1500 4x4, website said it would fit, it does not fit, as axle plate is Square on my truck, this kit have round axle plate that interferes with spring shackle bolts, would not fit or even be centered. SO I am returning them, this needs to be corrected on your website, it does not fit the 2026 Silverado 1500 2x2 or 4x4!
Great product!
It was easy to order and the stuff I ordered is just what I was looking for. The people who helped me was great
Great set up. Easy to install. Much better than the Timbren bump stops.
I have no problems with the quality or the install. My one problem is the instructions, when you order the stainless steel kit, it comes with a separate box to replace the hardware. That's totally fine, but it would be nice if they could work that in the instructions for when to install the stainless steel airlines because you can install them at the same time that you can the push in plastic lines. Besides that, these are an insane set of airbags. When I ride at zero psi cuz I got the ones with the internal jounce bumpers, I did not expect this but it smooths out my ride. That's a super huge plus.
The only reason I bought this kit is because I was told I could put zero psi when not towing and I would not lose the factory suspension comfort. That information was wrong its a horrible ride now and I regret getting these bags. Was also told that they don't off this kit without the stainless upgrade so I had to buy it, but when it shipped there was a separate box with the stainless kit and they regular stuff was in the same box as the bags feels like I got ripped off on this deal
This is a very nice kit. I installed on my new 2026 Silverado 2500hd. Installation was pretty straight forward, but still took a bit of thinking. After everything is mounted correctly there is a slight lean to the bags (not completely perpenticular to the mounting plates). I called Pacbrake support and they assured me this was normal and nothing to be concerned with. I had the equivalent AirLift kit on my 2007 Silverado 2500hd and I think I like the Pacbrake kit better. Everything seems a bet "beefier".
Parts fit perfectly, directions were very easy to understand.
