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, everyone, Steve here with etrailer.com. Let's take a look at our Pacbrake Alpha HD air bag suspension kit. It's a double convoluted for your rear axle rated at 5,000 pounds. Now, folks, this is a custom fit application for the 2005 through 2010 Ford F-250 and 350 super duty, two-wheel drive models. And you're gonna get precision brackets included with all the hardware you see before me today to make it a factory direct, bolt-on installation. So air springs, as you probably already know, are not gonna increase your vehicle's weight-carrying capacity, but they are going to help lift up and support the additional weight.
Now, these are not made for commercial cabin chassis trucks either, so I wanna put that out there. Now, if you're not sure or never heard of Pacbrake, they've been around for years and years, predominantly from the semi-truck kind of industry, so big, big trucks, big heavy-duty, high-quality springs and brackets, that's what you're getting folks. So, you can set the air pressure between 5 to 100 PSI on these double convoluted axle springs here. And as you see, again, you get all the airline, the cutter here for the airline and all the rest of the brackets, the hardware, everything you need for this installation. Now, these airlines are gonna be push fitting, so all you're gonna have to do is just make the cut exactly how the instructions tell you, and then simply just push that airline into the connector to make that connection.
Now, I've kind of got these just, just loosely assembled here today, nothing's tight, and this is more or less most of what this would look like when it's installed. Lemme step out of the way there again. But keep in mind there's gonna be some more brackets that are here on the table, on both sides that are gonna be attached to this as well to then help hold this to the frame of that vehicle. Now, as you know, this will give you a improved ride stability, air bags will help reduce rear-end swag, or sag rather, sway and bounce, giving you better handling on your load while you're driving. And again, folks, everything here, no drilling.
I know there's a lot of stuff. Don't be afraid of it, it's not too bad. Just take your time, read the instructions. We've probably got a video or two on our website as well of us installing these on your particular vehicle. Now, you're gonna use manual inflation with this particular kit.
It does not come with any kind of onboard air system or anything like that. That can be purchased separately here at etrailer.com as well. Folks, that is gonna wrap it up for our quick look together at this Pacbrake Alpha HD air bag suspension kit. I'm Steven, have a good one.
Don’t fit, worked on it for hours with no luck.
They need instructions to be more clear but fit very nicely i would recommend pacebrake
Going camping!!!
Worked out great
Thank you Joshua for your assistance.
Easy install and done exactly what I needed it to do
Excellent choice… Very high-quality… Took 4 to 5 hours to install… Which included new shocks getting all the tools together and clean up… Very happy thank you
Installed this past weekend. Haven't towed with it yet. Nice construction and finish. I have a 2025 Chevrolet Trail Boss 2500HD and the spacers are NOT needed. Measurement for needing the spacers in 7" and above between jounce cup and contact pad. My space was 5.5" to 6".
Awesome product easy to install and I really appreciate etrailer service
It was very easy install . The ride has improved a lot while towing my 41 ft. toy hauler , Thanks !!
Direct bolt on, plug and play
The product is a great product. After installation was completed and the air added to the air suspension, it raised the rear end of the van about 2-3 inches.A very nice improvement.
Installation instructions definitely need better quality diagrams.
Easy to install and work just as I had expected. Great finish on brackets and quality hardware. Easy to follow instructions. Highly recommend these airbags!
The 2" spacers are definitely not needed for a Trail Boss. I could barely get them in, and now the ride is super stiff. Now I have to get back under the truck and remove the spacers. Not looking forward to that. It was very difficult installation, for no reason.
Very well built brackets, installation was as explained in the instruction. Happy Camper!
