Features to know about

Support That Keeps Your Van Steady and Safe

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.

Zero-Pressure Comfort When Running Unloaded

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.

Tune Your Ride to Match the Mission

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.

Durability You Can Count On, Mile After Mile

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.

Installation That Doesn't Waste Your Weekend

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.

Flexible for Today, Ready for What's Next

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.

Video Transcript for Review of Pacbrake Vehicle Suspension - Alpha HD Pro Rear Double Convoluted Air Bag Kit - PB56RV

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha HD Pro Rear Axle Double-Convoluted Air Bag Suspension Kit. Now, this has been designed to fit the 2007 and newer Sprinters. As you can see there on your screen, I'm putting a more detailed list of all the Sprinters that this kit will work with. But on custom fit parts such as this kit, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Just 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 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 springs are going to add 5,000 pounds of rear support. This is gonna help you keep your Sprinter level and composed when the weight adds up. So you're not gonna have to worry about any more dragging at the end or sloppy cornering or headlight glare that's gonna blind oncoming traffic. These are gonna give you a stronger stance, more predictable handling, and peace of mind when you're behind the wheel of your Sprinter.

Now, bottoming out just doesn't feel rough, it can wreck your air bags. That's why this system includes internal jounce bumpers inside of each bag. So even with no pressure, your suspension has a built-in safety net. So you're gonna be able to safely run at 0 psi when unloaded, which means no harsh rebound, just that smooth factory-style ride. Now, 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're going to be able to fine tune that 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. So the manual inflation valves are gonna keep it effective and easy to manage on your own terms. So from long-haul deliveries to off-grid trails, your van is going to see more than just perfect pavement, and this system is built for that. These air bags are reinforced all the way through with heavy-duty endcaps, 20 internal support wires, we talked about the integrated jounce bumpers, and then these powder-coated steel brackets, and then corrosion-resistant hardware.

I don't have it all on the table here before me, but I do have a pretty good photo here of all the hardware that's going to be included with this kit. The hardware is corrosion-resistant. And it's gonna come with everything that you need to get this installed into place. The precision laser-cut brackets are designed to bolt cleanly to your Sprinter's factory mounting points with limited drilling required. So with those high-quality fittings and mounting hardware included, you're gonna be able to get these installed, and then get on down the road. So a nice thing about this kit is it's designed to work with your setup right now, and then wherever your upgrades may take you down the road. Again, you're gonna be able to inflate manually with standard air valves right out of the box, no extra parts needed. But maybe you already have an onboard compressor, that's great, because this system is going to connect easily to most existing setups that are out there. And then maybe you're planning for something down the road, like an in-cab wireless controller. That's not gonna be an issue, because the foundation's already being built in with this kit, making it easy to expand your control options when you're ready. So, as I mentioned, this is going to give you up to 5,000 pounds of load-leveling support. But be aware of the fact that this kit doesn't actually increase your Sprinter's weight carrying capacity. So you do wanna make sure that you're not exceeding your manufacturer's recommended weight limit. If you have any other questions, don't hesitate to reach back out to us. We do wanna make sure that you're getting exactly what you need and want. 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.

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.



by:

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 !



by:

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



by:

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,



by:

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.
