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 for your 2013 and newer Ford Transit 350HD, both the 2-wheel and 4-wheel drive models, the Class C motorhomes, and this kit is for the 2-wheel and 4-wheel drive dual rear-wheel cargo vans only. And this will not fit passenger vans, XL or XLT models, or those with all-wheel drive. So, all that to say, it is important that you use our Vehicle Fit Guide here at etrailer.com. Simply input 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 I'm sure you know, your factory suspension can struggle under real-world loads. If you're delivering cargo, towing a trailer, or building out a full van conversion, these airbags are gonna add up to 5,000 pounds of rear support, helping to keep your vehicle level and composed when the weight adds up. So, no more dragging rear ends, sloppy cornering, or headlight glare that blinds oncoming traffic. Just a stronger stance, more predictable handling, and peace of mind when you're behind the wheel. Now, a cargo run doesn't ride the same as a weekend trip, and your suspension should reflect that.
With air pressure adjustability from five to 100 PSI, you're gonna be able to fine-tune support based on how much gear you're hauling. You can drop the pressure when you're running light for a smoother ride or pump it up when the van is packed full. The manual inflation valves are going to help keep it effective, and it's gonna be very easy to manage on your own terms. So, from long-haul deliveries to off-grid trails, your van sees more than perfect pavement, and this system is built for that. These airbags are reinforced all the way through with heavy-duty end caps, 20 internal support wires, and powder-coated steel brackets.
So, the hardware as well that I don't have laid out here on the table, but I got a nice layout there in a photo there showing you everything that's included. All the hardware is gonna be corrosion-resistant. You have thick roll plates at the top and the bottom of the bags, and basically, you have everything that you need in a system that's gonna hold up to real-world hauling through heat, cold, salt, and anything else you might throw at it. So, this is going to be relatively simple to install. Again, these precision, laser-cut, custom-fit brackets are designed to bolt cleanly to your factory mounting points with limited drilling.
Instructions are included to guide you through that installation process, and this kit is designed to work with your setup as it stands now, or wherever your upgrades may take you down the road. So, again, you're gonna be able to inflate manually with the standard air valves right out of the box. No extra parts are gonna be needed, but if you already have an onboard compressor, that's great too because these are gonna connect easily to most existing setups. Or maybe you're planning for an in-cab wireless controller sometime down the road, that's not gonna be an issue either, because with this kit, the foundation is already being laid, making it easy to expand your options when you're ready. Now, as I mentioned, this is going to give you up to 5,000 pounds of additional leveling support, but be aware of the fact that these are not going to actually increase your vehicle's weight carrying capacity, so you wanna be sure that you're not exceeding your manufacturer's recommended weight limit. If you do pick this kit up, we would love to hear back from you. We wanna hear your experience with the installation and using this system, so you can share your experiences with us by dropping a comment or leaving a review on this product page. And if you have any other additional questions, don't hesitate to reach back out to us, whether it's by phone, email, or chat. Ultimately, we wanna make sure that you're getting exactly what you want and need. Well, I think that's gonna wrap up our look today. I do hope that our time together was helpful for you. Again, my name is Andy, thank you for joining me.

Sorry to hear that, Travis. Is your 2016 Ford Transit T350 a passenger van, XL/XLT model, or one with AWD? And lastly, is it a dually? I know you probably don't want to be answering questions like this, but it is the first time I have heard of one of their air bag kits completely not fitting.
