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 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. Alpha HD air bags are reinforced all the way through with heavy-duty end caps, 20 internal support wires, and powder-coated steel brackets. Toss in 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 Sprinter's factory mounting points with limited drilling required. Just smart engineering that fits the way it should which is perfect for the DIY-er. 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 with a stronger, steadier van in just a few hours.
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, everyone, Steve here with etrailer.com. Let's take a look at our Pacbrake Alpha HD Pro Airbag Suspension Kit for the rear axle, rated at 5,000 pounds. Now, folks, this is a custom-fit application. Make sure you're double-checking our Fit Guide here at etrailer.com to be sure you're getting the right parts for your specific setup. Now, these are gonna include precision brackets that are gonna bolt to your factory attachment points, and everything here has a nice, elegant powder-coat finish on it. If you're not familiar with Pacbrake, they've been around for years and years.
They've been mainly coming out of the semi tractor trailer world, so everything made with the highest standards, highest quality, just like you would see on those big, big trucks. Same thing here, same quality. They didn't skimp on anything. I'm actually really impressed with the makeup, the way it comes packaged. You're gonna get everything that you see before me, and there's an expanded view of all of it laid out on the table as well.
So, again, I've got these kinda mocked up today just to give you a little better look from the front and everything of what they could potentially look like when they're installed. Load support, up to 5,000 pounds of additional load-leveling support. And again, everything here is just kinda lightly put on right now. You have your fitting here, that's just a push-in fitting for your airline hose. There is no compressor kit, onboard kit included with this kit.
However, you can get that separately or you can upgrade later on down the road when you're ready to. These can have support between five PSI and 100 PSI, depending on what you set it at, and depending on your needs. They're gonna improve your ride stability by reducing rear sag, sway and bounce, and giving you just a better control and comfort of your ride whenever you're driving with your gear and everything. Now, just remember, folks, these do not add any support or add any weight-carrying capacity, rather, they support the weight that's in the truck already, so you're not adding 5,000 pounds to your suspension, you're giving 5,000 pounds of support on that suspension. So, this will get your ride height if you're sagging in the back, back up to level, keeping your headlights straight on the road where it's safe, and keeping pressure back on the front axle where it needs to be for traction and those kinda things as well.
Well, if you have any questions about this or any of our other kits that we carry here at etrailer.com, just reach out to us by phone, chat, or email. We'd be more than happy to assist you. I'm Steven, please stay safe out there on the roads, and while you're towing.
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!
