Demanding trailer, camper, or payload weight can leave your truck squatting and less controlled. These air springs add up to 7,500 lbs of leveling support to reduce sag, sway, and bottoming, while internal jounces let you run 0 psi unloaded.
Your truck can feel composed empty, then change quickly once substantial pin weight, a slide-in camper, or a heavy work payload settles onto the rear suspension. The two adjustable rear air springs provide up to 7,500 lbs of load-leveling support to help bring a sagging rear back toward normal ride height while reducing sway and bottoming under load. Instead of treating that capacity as a target, you can tune the air pressure to the weight your truck is actually carrying.
A truck built for serious towing or hauling may still spend plenty of miles without that weight on the rear suspension. Internal jounce bumpers let you increase air pressure when a substantial load calls for more support, then reduce the air springs to 0 psi when the extra weight comes off. Those internal jounces protect the air springs against bottoming when suspension travel is used up, so you don't have to maintain air pressure simply to protect the bags during unloaded driving. The result is adjustable support that can work around both sides of your truck's job instead of treating every mile like a loaded one.
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 before raising the rear, with wheel removal optional if you want more working room. The installation uses the existing factory strike-block mounting locations for the upper support brackets, while the air spring assemblies secure to the axle with lower brackets and axle straps. Some brake-line hardware is temporarily moved and relocated with the included brackets to create the clearance the air springs need, and the driver-side emergency-brake cable is repositioned to prevent interference. Once the springs are properly aligned and the upper brackets are sitting flat against the frame, you'll torque everything down, then route the braided stainless steel air lines away from brake lines, fuel lines, wiring, and other potential trouble spots with enough 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 when your truck regularly switches between demanding loads and unloaded driving. You can add a Pacbrake Bravo Wireless Air Control Kit with XD Compressor (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, everybody, Andy here with etrailer. Let's take a quick look together at this Pacbrake ALPHA XD PRo rear axle airbag suspension kit with internal jounce bumpers and stainless steel hardware. So this has been designed to fit your 2019 to current International trucks, the CV series with either the two-wheel or four-wheel drive model, and the 2019 to current Chevrolet Silverado, the 4500, 5500, and 6500, again, either the two wheel or four wheel drive model. Now, on custom fit parts, such as this kit, I do recommend taking advantage of our vehicle fit guide here at etrailer, pop in the year, make, and model of your vehicle, answer any other questions that I might have for you, and our fit guide will confirm if this works for you or if we have something comparable that will work for you. As you can see, I do kind of have them loosely put together just to give you an idea of what this is going to look like when you have these installed on your truck, but as you know, when the load gets heavy, your truck's going to need more than just your factory rear springs hanging on for dear life. These airbags are going to give you up to 7,500 pounds of rear axle support.
It's going to help keep your truck level and steady even when the trailer is loaded, your bed is packed, and the miles are long. So no more rear end sagging, throwing off your braking or steering, or your headlights pointing up into the sky. Now, bottoming out just doesn't feel rough. It can actually wreck your airbags. That's why this system includes jounce bumpers inside of each bag.
You can see that there on an example cutaway that I put there on your screen. So even with no air pressure, your suspension has a built-in safety net. You're going to be able to safely run at zero PSI when unloaded, which means no harsh rebound, just that smooth factory style ride. Now, this kit, as you can see here, includes stainless steel braided airlines. These are more durable and resistant to wear compared to standard rubber lines.
You're also going to get stainless steel roll plates, which help protect the airbags along with Schrader valves so you can easily inflate or adjust the air pressure using the standard or a standard air source, rather. Now, on your screen, I've got some pictures there. The top picture is the standard hardware and brackets that this is going to come with, but, again, this includes, also, the stainless steel upgrade, and you see the parts there for the stainless steel parts at the bottom. So I just wanted to show you everything that you're going to be getting. You're not going to be using every piece of the hardware, but you're going to have what you need here, especially with the stainless steel hardware to get this put together and mounted into place.
So I didn't have room for all that hardware on my table, so I just wanted to show you those images to get you a better comprehensive idea of what you're going to be getting. So every haul is going to be different. So these airbags give you full control over your ride height and firmness with adjustable air pressure from five to 100 PSI. If you're hauling a fifth wheel or a full bed of gravel, you can crank that pressure up. If you're unloaded and heading home, you can drop that pressure down for a softer ride with manual inflation valves included. So you're going to be able to tune your suspension for the day's work, and so it's pretty straightforward. These airbags are built with one-inch thick corrosion resistant end caps, and they're reinforced with 20 internal support wires for maximum strength under load. These do include these really great premium powder coated laser cut mounting brackets, so you're not going to have to worry about drilling or welding to your vehicle. These are, again, custom design for your International or Silverado truck. That stainless steel is going to be great. It's going to hold up a lot better than the standard material that these come with. You're not going to have to worry about rust and corrosion, and so it's a definitely, again, I'm repeating myself here, but the stainless steel is definitely going to be a great upgrade to this kit that you're getting. So again, this is going to give you up to about 7,500 pounds of additional leveling support, but just be aware that airbags don't actually increase your truck's weight carrying capacity. So you want to make sure that you don't exceed your manufacturer's recommended weight limit. One final note, if you are looking for help for getting these installed on your truck, on this product page, we have a link underneath the photo section, and if you click that link, that's going to take you to our installer locator. Answer the questions that it has for you, and that locator will find an installer that etrailer has partnered with in your area to do the install for you. If you happen to have any other questions, give us a call. We want to make sure that you're getting exactly what you need. Well, again, my name's Andy. Thank you for joining me.
