To see if this custom-fit item will work for you please tell us what vehicle you'll use it with.
Heavy trailers and full beds push your suspension to its limit. This 7,500 lb air helper spring kit helps restore ride height, reduce sag and sway, and keep your truck more controlled when fully loaded.
Each Alpha XD PRO air spring includes an internal jounce bumper that acts like a secondary support during suspension compression. This allows the system to run at 0 psi when unloaded without leaving the bags unprotected, while added air pressure under load helps level the truck and control suspension movement for more consistent handling.

Hi, everybody, Andy here with etrailer. Let's take a quick look together at this Pacbrake Alpha XD Pro Air Helper Spring Kit with Stainless Steel Hardware. Now, this rear axle Air Helper Spring Kit is designed to fit your 2007 to 2009 Dodge Sprinter 3500, then your 2010 and newer Mercedes-Benz Sprinter 3500. On custom-fit parts such as this kit, I do recommend taking advantage of our Vehicle Fit Guide here at etrailer. Just 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, this kit does use the Alpha XD Pro Air Springs, which are rated to handle up to 7,500 pounds of load-leveling support.
So, when you hook up your trailer or you load your Sprinter down, these air springs can inflate to help reduce rear sag, helping your van to sit more level. Now, this is gonna make a big difference in how your Sprinter feels and drives. Steering is going to be more controlled, braking is going to be more predictable, and your headlights are going to stay aimed where they should be instead of pointing up to the sky when you have that heavier load. Now, one standout feature is going to be the internal jounce bumpers, which are built into every air spring. On your screen, I do have kind of a cutaway there showing you that jounce spring inside of the airbag, or jounce bumpers, rather.
These bumpers are gonna act like built-in bump stops, so when the truck is unloaded, you can actually run the system to zero PSI. That means that you're still gonna get a near-factory ride when you're not hauling anything, while those internal jounce bumpers are gonna protect the air springs and soften the harsh impacts if you hit a pothole or a dip in the road. Now, durability is another big focus. This kit uses braided stainless steel airlines, as you see right here, stainless steel fittings. And I do have things kind of loosely put together here with the brackets and the hardware, so I just kinda wanted to give you a feel of what the parts are gonna look like when you put them together and install them on your Sprinter.
You're gonna have stainless steel roll plates, stainless steel Schrader inflation valves. And that stainless steel material, as you know, is gonna do a great job of resisting corrosion, it's gonna help prevent leaks over time, and this is gonna be a good long-term solution even in those harsher weather environments or harsh road conditions. So, everything that you need comes in the box for a clean, bolt-on installation. Again, using vehicle-specific brackets for your Sprinter 3500. And then you're also going to, of course, get these two Alpha XD Pro Air Springs, and then six feet, so six foot here and six foot here, of braided stainless steel airlines, and then they're going to tie into the nylon airlines with the included fittings.
Now, again, you're gonna get the stainless steel mounting hardware, the stainless steel roll plates, and then the stainless steel Schrader inflation valves, nylon tie straps, and then instructions to guide you through the installation process. Now, I do wanna let you know that this kit does include extra hardware in order to accommodate many other kits, so there will be extra hardware left over after the installation. You can inflate the air springs manually using the included valves, or you can connect them to an onboard air system or remote compressor if you want to adjust the air pressure from the cab or while you're parked at the campsite, so we do have those compressor options available here at etrailer as well. But again, you're gonna get everything that you see here. Now, if you happen to have any other questions, whether it's about this kit or anything else that we have here at etrailer, don't hesitate to reach out. We do wanna make sure that you get exactly what you need. Well, again, my name is Andy, thank you for joining me.
Ratings & Reviews
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 !
Great quality!
So far so good two trips with camper and worked great !
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
Thanks Ashley. I did not open yet wait next week Friday I work on van
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.
Lifts the truck back to normal with a heavy load. Feels so much safer on twist and turns and even just pulling into the store.
I got it to work but the J Hooks that came with the kit were extremely short and I didn't want to wait for a new part but I made it work
Product is well constructed and installation is straightforward. But you cannot build the kit and slip it in, you have to leave the top bracket off and install it after setting the lower bracket and air bag in place. I will note, I was working off jack stands and a floor jack, not on a lift.
Order and delivery was easy and quick. Installation instructions were clear and was an easy install. Great product.
Product was exactly as described delivered fast and easy to install. Only two bolts didn’t fit. No problem had some spare ones that worked. Would definitely recommend this product and company
My kit had hardware that was too short and some hardware that was too long. Making the install difficult, having to use my old hardware to complete. The kid I ordered was supposed to fit my vehicle, not so much. All of my boxes had been re-taped, as if it was returned from a previous customer.
When I'm occasionally towing long distances it helps my Ram 1500 a lot. However, there's no psi happy spot for a smooth factory ride after the towing ceases and daily commutes return.
This product is everything they said it was. It was very easy to install my Ford transit T250 handles great now in my trailer hitch. It’s not dragging the ground. Thank you for a great product.
First off this is my first experience with air bags. When I was a kid it was air shocks. First, off tip of the hat goes to etrailer for fast delivery. Many times I read reviews where people complain about directions. These people I would guess have very little mechanical skills. The included instructions with these is very comprehensive and thorough. The would make this easy for the average guy. Second, soon as you start to unpack the parts you can tell this is heavy duty well made product. Everything fit perfectly. I gained 3 inch’s at 50 lbs. my build is a b class transit 250 van. 148EL. When you start building these things the weight adds up quick. Was starting to regret not getting a 350 but this saved the day. No miles on it yet but certainly clearance issue is solved,
