When the load gets heavy, your van shouldn't feel unstable. These air bags help keep you level and in control, so you can handle passengers, gear, and towing duties with confidence—no more fighting sag, sway, or a soft suspension.
Factory suspension can struggle under real-world loads—if you're delivering cargo, towing a trailer, or building out a full van conversion. Alpha HD air springs add up to 5,000 lbs of rear support, helping keep your Sprinter level and composed when the weight adds up. 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 behind the wheel.
A cargo run doesn't ride the same as a weekend trip and your suspension should reflect that. With air pressure adjustability from 5 to 100 psi, you can fine-tune support based on how much gear you're hauling. Drop pressure when you're running light for a smoother ride or pump it up when the van's packed full. Manual inflation keeps it simple, effective, and easy to manage on your own terms.
From long-haul deliveries to off-grid trails, your van sees more than perfect pavement and this system is built for it. One-inch thick, corrosion-resistant end caps and reinforced with 20 internal support wires for maximum strength under load. Heavy-duty roll plates protect the bags from chafing and extend lifespan. Powder-coated steel brackets fight back against rust, road salt, and rough seasons. If it's bitter cold, scorching heat, or mud-slicked trails, this system is made to outlast whatever the road dishes out, mile after mile, load after load.
This kit is designed with DIY-ers in mind. Precision brackets bolt to existing mounting points with no drilling, and all components come pre-cut and ready to install. Manual inflation valves mount easily to the rear bumper or license plate bracket. No complicated wiring or air tools required. Just a straightforward upgrade you can knock out in a few hours and feel on the very next trip.
Whether you're keeping it simple or planning a full onboard air system, this kit works with your setup. Use the manual inflation valves out of the box or tie into an existing compressor when you're ready. Planning to add wireless in-cab control later? It's compatible with that too. Your van evolves, and your suspension should be ready to grow with it.

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 the 2007 and newer Sprinters, and on your screen, I'm putting a little more of a detailed list there showing you the fits. But on custom-fit parts such as this kit, I highly recommend taking advantage of our Vehicle Fit Guide here to etrailer.com. Input the year, make and model of your vehicle, and our Fit Guide will confirm if this will work for you, or if we have something comparable that will work for you. Now, as you know, your factory suspension can struggle under real-world loads, and if you're delivering cargo or towing a trailer or building out a full van conversion, these springs are going to give you up to 5,000 pounds of rear support.
So, these are gonna help keep your Sprinter level and composed when the weight adds up, so you're not gonna have to worry about any more rear end drag or sloppy cornering, or headlight glare that blinds oncoming traffic. Just a stronger stance with more predictable handling, and peace of mind when you're behind the wheel of your Sprinter. Now, a cargo run doesn't ride the same as a weekend trip, and your suspension should reflect that. So, with air pressure adjustability from five to 100 PSI, you're gonna be able to fine-tune your support based on how much gear you're hauling. You're just gonna drop the pressure down when you're running light for a smoother ride, and then pump it up when your van is packed full.
The manual inflation valves are going to help keep this effective, and easy to manage on your own terms. Now, from long-haul delivery to off-grid trails, your van sees more than perfect pavement, and so this system is built for that. These airbags are reinforced with heavy-duty end caps, 20 internal support wires and powder-coated steel brackets. And then also, it does come with a complete hardware kit, as you can see there on your screen, and the hardware is premium corrosion-resistant, so it's gonna hold up really well along with all the other parts of this kit. And so this kit is designed to work with your setup as it stands right now, or wherever your upgrades may take you later on.
Again, you're gonna be able to inflate manually with the standard air valves right out of the box, no extra parts needed, but if you already have an onboard compressor, that's great, because these are gonna connect easily to most existing setups that are out there. And then maybe you're planning for an in-cab wireless controller sometime down the road. That's not gonna be a problem, because with this kit, you're already laying the foundation to expand your control options when ready. As I mentioned, this kit is going to give you up to 5,000 pounds of load-leveling support, but be aware of the fact that these airbags do not actually increase your weight-carrying capacity, so you wanna make sure that you're not exceeding your manufacturer's recommended weight limit. If you have any other questions or concerns, don't hesitate to reach back out to us.
We do wanna make sure that you're getting exactly what you want and need. Well, that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
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
Awesome product easy to install and I really appreciate etrailer service
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".
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!
