When the load gets heavy, your truck shouldn't feel like it's fighting you. These air bags help you stay level, drive steady, and stay in control so you can tow with confidence and handle heavy loads without second-guessing your 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 Pro air bags 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.
Bottoming out doesn't just feel rough, it can wreck your air bags. That's why this system includes jounce bumpers inside each bag, so even with no air pressure, your suspension has a built-in safety net. You can safely run at 0 psi when unloaded, which means no harsh rebound just that smooth, factory-style ride.
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 Pro air bags are reinforced all the way through with heavy-duty end caps, 20 internal support wires, integrated jounce bumpers, 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 and mounting hardware included, you'll be back on the road with a stronger, steadier van in just a few hours.
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 Pro 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 pack Brake Alpha HD PRO rear axle, double-convoluted airbag suspension kit with internal jounce bumpers. Now, this kit has been designed fit your 2007 and newer sprinters, the 3,500 and the 45,000 with the dual rear wheel model. And as you can see, it's gonna work with the two wheel and four-wheel drives. Now, I do wanna point out that this is not going to fit the single-rear wheel models and it's not gonna fit the e-sprinter models, and also it's not going to fit models with ride height sensors. Just so you're aware of all that going in.
Now, since this is a custom fit kit, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. You'll enter the year, make, and model of your vehicle, and our fit guide will confirm for you if this kit will work or if we have something comparable that will work for you. So as you know, when the load gets heavy, your sprinter is going to need more than just the factory rear springs hanging on for dear life. These airbags are going to add up to 5,000 pounds of rear axle support, keeping your sprinter level and steady, even when the trailer that you're hauling is loaded or the cargo area is packed and the miles are long. With this kit, you're not gonna have to worry about rear-end sag anymore, throwing off your braking and steering, or having your headlights point up, instead of on the road in front of you.
Now, bottoming out doesn't just feel rough, it can wreck your airbags. That's why this system includes jounce bumpers inside of each bag, so that even when the air pressure is low or you have no air pressure, your suspension has a built-in safety net. So as you can see on that cutaway that I have there on your screen, that shows you how that internal jounce bumper is installed inside of that bag. So because of that bumper, you're gonna be able to safely run at zero PSI when unloaded, which means no harsh rebound, just hit smooth factory style ride. So of course, every haul is gonna be different.
That's why these airbags give you a full control over your ride height and firmness with adjustable air pressure from five to 100 PSI, if you're hauling a fifth-wheel trailer or a full bed of gravel, you can crank up that pressure and then when you're unloaded and you're heading home, you can drop that pressure back down, giving you a softer, more comfortable ride. So with the manual inflation valves included, tuning your suspension for that day's work is gonna be very simple and straightforward. And of course, extreme hauling demands extreme durability. These springs are built with one-inch thick corrosion resistant end caps, which you can't see right now because I do have them slightly put together here, installed loosely how they're gonna be installed on your sprinter. But the bags also have 20 internal support wires giving you maximum strength under that heavy load.
Then we have these heavy duty roll plates on the top and the bottom. They're gonna protect the bags from chafing, they're gonna extend their lifespan. And then these powder coated steel brackets are gonna resist rust and corrosion. So they're gonna hold up really well in all weather conditions, all types of road conditions. These precision laser cut brackets are designed to bolt cleanly to your sprinter's existing mounting points. So you're not gonna have to worry about welding or drilling. Just going to install with the included hardware that you see here on my table. And this kit is designed to work with your setup right now or wherever your upgrades may take you tomorrow. You're gonna be able to inflate these bags manually with the standard air valves right out of the box. No extra parts needed, but if you already have an onboard compressor, these connect easily 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 the foundation is gonna be laid with this kit. So you're gonna be able to expand your control options when you're ready. Now, I did say that this does give you that load support of up to 5,000 pounds, but I do wanna make you aware of the fact that this will not actually increase your sprinter's weight carrying capacity. So you wanna make sure that you're not exceeding your manufacturer's recommended weight limit. If you do pick this kit up, we'd love to hear back from you regarding your experience regarding the installation and the operation, and you can do that by dropping a comment or leaving a review on this product page. And if you have any other additional questions, don't hesitate to give us a call. We'd love to hear from you and help you out. Well, that's gonna wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
Easy to install and looks like it’s a high-quality product
haven't received or used it yet but pretty darn excited
The brackets are not built heavy enough
Easy install. Will pull trailer 3000 miles on vacation and see how it performs to Montana on highways and Forest Service roads.
good product , good strong solid metal parts and heavy bags. The instructions were not so hot but was easy to figure out and quick delivery !
Where to start I have 1500 pounds of tools in my 150 Chevy had them installed and it totally changed the ride and handling of the truck haven’t pulled anything yet but I’m amazed on how different the truck is already I Baught the ones with the bump stops in them the HD ones
I'm Vincent J,
My experience with loading my truck and seeing the difference with these air bags from PacBrake, it does look way better and the truck feels a bit more stable running atspeed limit (65mph) after that it does feels jumpy if you go over potholes, but overall I'm happy with the product, thanks Etrailer,
2020 Ram 1500.
Installation is fidgety with lining everything together for the upper bracket with u-bolt(reason for 4 stars), but still preferred over cutting the bump stop mounts off. Replaced the Timbrens with this and it is night and day difference in ride quality both unloaded and towing.
Would purchase again.
