Features to know about

Built to Handle Serious Loads and Keep You in Control

When the load gets heavy, your van needs more than just rear springs hanging on for dear life. Alpha XD air springs add up to 7,500 lbs of rear axle support, keeping your Sprinter level, steady, and confident even when the cargo is packed, the upfit is heavy, and the road gets long. No more rear-end sag throwing off your braking and steering, or headlights pointing into the sky. With air bag support underneath, you keep control of your ride, your cargo, and your peace of mind—even when you're hauling tools, gear, or a mobile workspace.

Adjustable Support for Every Haul

Every load is different. That's why Pacbrake gives you adjustable air pressure control between 5 and 100 psi. Need full strength for a fully loaded work van? Pump it up. Running empty between jobs? Drop the pressure for a smoother ride. Simple manual inflation lets you adjust your suspension without the guesswork, so your van feels balanced and comfortable whether you're packed to the roof or running light.

Made to Survive the Real World

Extreme hauling demands extreme durability. Alpha XD springs are built with 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 city streets full of potholes, this system is made to outlast whatever the road dishes out, mile after mile, load after load.

No Drill, Factory-Grade Install

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 existing mounting points without welding or drilling your frame. Just smart engineering that fits the way it should which is perfect for the DIY-er. 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—without a trip to the fab shop.

Flexible for Now, Adaptable for the Future

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 XD 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 XD Rear Axle Double Convoluted Air Bag Kit - PB36RV

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha XD Rear Axle, Double-Convoluted Air Bag Suspension Kit. Now this kit has been designed to fit your 2007 and newer Sprinters, the 2500 and the 3500 with two-wheel or four-wheel drive, and this is designed for the single rear wheel model only, so this will not work with the dual rear wheel models, and it will also not fit the E-Sprinter models nor the models with the ride height sensors. So on custom fit parts such as this kit, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. 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.

Now, when the load gets heavy, your Sprinter is going to need more than just those rear factory springs hanging on for dear life. These air bags are gonna give you up to 7,500 pounds of rear axle support, keeping your Sprinter level and steady even when your trailer is loaded, your cargo area is packed, and the miles are long, so no more rear sag throwing off your braking or your steering or having your headlights point up to the sky when they should be actually pointing down on the road. So every haul is gonna be different. That's why these air springs give you full control over ride height and firmness with adjustable air pressure from 5 to 100 psi. So if you're hauling a fifth wheel or a full bed of gravel, you can just crank up the pressure, and then when you're unloaded heading home, just drop that pressure back down for a softer ride.

With the manual inflation valves, tuning your suspension for the day's work is gonna be very easy. Extreme hauling does demand extreme durability, and these springs are built with one-inch thick corrosion-resistant end caps that you can't see because they do have them kind of loosely assembled here, but the bags also are reinforced with 20 internal support wires giving you maximum strength under that load, and then on the top and the bottom we have these heavy-duty roll plates that are gonna protect those bags from chafing and help extend their lifespan. These powder-coated steel brackets are custom fit, and they're gonna fight back against rust and corrosion, so this kit is going to be able to handle whatever you throw at it no matter the road conditions or the weather conditions. These are precision laser-cut brackets. They are designed to bolt cleanly to your Sprinter's existing mounting points without welding or drilling to your frame.

They're gonna install with the included hardware that you see here. And so this kit is designed to work with your setup today and wherever your upgrades are gonna take you tomorrow. Again, you can inflate these manually with standard air valves right out of the box, no extra parts needed, but if you already have an onboard compressor, these are gonna connect easily to most existing setups, and then maybe you're planning for something like an in-cab wireless controller sometime down the road. That's not gonna be an issue because with this kit you're building that foundation to where you could expand your control options when you're ready. So, again, this is gonna give you up to 7,500 pounds of load-leveling support, but it is important to note that this is not going to 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 would love to hear back from you regarding your experience with getting these installed and using this kit, so you can share your experience with us by dropping a comment or leaving a review on this product page, and if you have any other additional questions for us, don't hesitate to give us a call. We'd love to help you out further. 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.
