5,000-lb Capacity. When the load gets heavy, your truck shouldn't feel like it's fighting you. These air bags help you stay level and in control so you can tow with confidence and handle heavy loads without second-guessing your suspension.
When the load gets heavy, your truck needs more than just rear springs hanging on for dear life. Alpha HD air springs add up to 5,000 lbs of rear axle support, keeping your truck steady even when the trailer is loaded, the bed is packed, and the miles are long. No more rear-end sag throwing off your braking and steering, or headlights pointing into the sky. With air bag support underneath, you keep control of your ride even when you're towing a travel trailer or moving a serious payload.
Every load is different, and this system adjusts to match. Alpha HD air springs let you fine-tune ride height and firmness with air pressure from 5 to 100 psi. When carrying heavy weight, add air to level your suspension and maintain steady handling. Running without a load? Drop to the minimum pressure for a smoother, more compliant ride without stiffness or bounce. Manual inflation valves are included, so tuning your setup for each trip is straightforward and dependable.
Air bags are only as strong as their weakest link. That's why Alpha HD bags are reinforced from end to end with heavy-duty end caps, 20 internal support wires, and powder-coated steel brackets. Add corrosion-resistant hardware and thick roll plates, and you've got gear that holds up to real-world hauling through heat, cold, salt, and slop.
Adding serious load support shouldn't mean losing a whole weekend. The precision laser-cut brackets are designed to bolt cleanly to your truck's existing mounting points with minimal drilling. Just smart engineering that fits the way it should, which is perfect for the DIYer. Manual valves mount through license plate fastener holes or a location of your choosing (which may require drilling). With high-quality fittings, pre-bent brackets, and mounting hardware included, you'll be back on the road in just a few hours without a trip to the fab shop.
This kit is designed to work with your setup today and wherever your upgrades take you tomorrow. You can inflate manually with standard air valves right out of the box, no extra parts needed. Already have an onboard compressor? The Alpha HD system connects easily to most existing setups. Planning for an in-cab wireless controller down the road? No problem. The foundation is already built in, making it easy to expand your control options when you're ready.

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha HD Rear Axle Double Convoluted Airbag Suspension Kit. Now, this kit has been designed to fit your 2012 and newer Ford F-450, F-550, and F-600 commercial cabin chassis, both the two-wheel and four-wheel drive models. Now, I do recommend going through our vehicle fit guide here at etrailer.com, insert the year, make, and model of your vehicle and our fit guide will confirm if this kit will work for you or if we have something comparable that will work for you. So as you know, when the load gets heavy, your truck is going to need more than just those factory rear springs hanging on for dear life.
These airbags are going to give you up to 5,000 pounds of rear axle support, keeping your truck level and steady even when the trailer is loaded, the bed is packed, and the miles are long, so no more rear-end sag is going to be throwing you off, throwing off your braking or steering or headlights pointing into the sky. Now, as you no doubt know, every haul is going to be different. That's why these air springs give you full control over the ride height and the firmness, with adjustable air pressure from five to 100 PSI. If you're hauling a fifth wheel or a full bed of gravel, you're just gonna crank up the pressure and then when you unload it and you're heading home, all you gotta do is drop that pressure back down for a softer ride. With the manual inflation valves included and air line, tuning your suspension for the day's work is gonna be very easy, very straightforward.
Now, extreme hauling demands extreme durability, and these springs are built with one-inch thick, corrosion-resistant end caps, which you can't see because of these roll plates. I do, as you see here, have 'em kind of loosely put together to kind of give you an idea of how these are gonna be put together when you install them. But the end caps are going to be corrosion resistant. And then these bags are reinforced with 20 internal support wires, giving you maximum strength under that load. And then we have these heavy-duty roll plates here on either end and they're going to protect the bags from chafing and they're gonna help extend the lifespan of the bags.
And then our custom-fit, powder-coated steel brackets are gonna fight back against rust, corrosion, road salt, and everything that's gonna be exposed to. If it's bitter cold, scorching heat, or mud slick job sites, this system is built and made to outlast whatever the road dishes out on them, mile after mile and load after load. Now, back to these brackets here, these are precision laser-cut brackets and these are designed to bolt cleanly to your truck's existing mounting points without welding or drilling to your frame. And just as a side note, I'm very impressed with the overall quality that Pacbrake is providing here. These brackets are are not only, as I mentioned, precision cut, but the powder coating on here is very premium, in my opinion.
I've dealt with other manufacturers' airbag kits before and while they have their strong points, just the premium feel of the materials used with the bags and the hardware here, in my opinion, are exceptional from Pacbrake here. So if you're looking for a premium option with an airbag kit, this is definitely going to be the way to go. Now, you're gonna be able to, as I mentioned, inflate manually, and you're gonna be able to do that with the standard air valves right out of the box, no extra parts needed. And then if you already have an onboard compressor, these are going to easily connect to most existing setups. And then if you're planning for an in-cab wireless controller down the road, that's not gonna be an issue because with this kit, you're laying down the foundation for that. So it's gonna be very easy to expand your control options when you're ready. So again, this has a load support up to 5,000 pounds, and I do wanna point out though that these air springs do not actually increase your truck's weight carrying capacity. So because of that, you do not wanna exceed the manufacturer's recommended weight limit. This does include everything that you see here. You're gonna get the hardware, the U-bolts, additional brackets, and air line, everything that you need to get this installed into place. And if you do decide to pick this up, we would love to hear back from you regarding your experience with the installation and the operation of this kit.
