Features to know about

Built to Handle Serious Loads and Keep You in Control

When your truck or van is built to carry serious weight, factory suspension alone won't cut it. Alpha XD (Extreme Duty) air springs add up to 7,500 lbs of rear axle support to keep your vehicle level and steady under pressure. If you're hauling heavy gear or equipment, you stay in control with less squat, better stability, and more predictable braking.

Adjustable Support for Every Haul

Some days you're maxed out, others you're running light. With Pacbrake's 5 to 100 psi adjustable range, you get the right support for every trip. When carrying heavy weight, add air to level your suspension and maintain steady handling. Running without a load? Drop to the minimum pressure for a smoother, more compliant ride without stiffness or bounce. Manual valves let you adapt your suspension to whatever the day throws at you.

Made to Survive the Real World

Built for demanding commercial use, Alpha XD springs use one-inch thick, corrosion-resistant end caps and 20 internal support wires for extreme strength. Heavy-duty roll plates reinforce mounting points and protect the air springs from wear, and powder-coated steel brackets hold up to rust, road salt, and long seasons of abuse. From scorching heat to frozen job sites, this system is made to outlast whatever the road dishes out.

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 vehicle's existing mounting points with minimal drilling. Just smart engineering that fits the way it should, which is perfect for the DIYer. 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 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. Inflate manually right out of the box - no extra parts required. Already running an onboard air system? The Alpha XD integrates easily. Planning to add a wireless controller later? No problem. With standard ports and fittings already in place, the foundation is 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 - PB39RV

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha XD rear axle double convoluted airbag suspension kit. Now this kit has been designed to fit your 2011 to 2016 Ford F-250 and F-350 Super Duty, either with the two or four wheel drive, then your 2011 to 2014 F-450 Super Duty. Again, with either the two or four wheel drive. I do wanna let you know that this will not, this will fit rather models with or without a fifth wheel hitch. Now in custom fit parts such as this kit, I do recommend taking advantage of our vehicle fit guide here at etrailer.com.

Simply 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, when the load gets heavy, your truck is gonna need more than just those factory rear leaf springs hanging on for deer life. These airbags are gonna give you up to 7,500 pounds of rear axle support, keeping your truck level and steady. Even when the trailer is loaded, the bed is packed and the miles are long. So no more rear end sag throwing off your braking and steering or headlights pointing up to the sky.

Now every haul is going to be different. That's why these air springs are gonna give you full control over the ride height and firmness with adjustable air pressure from five to 100 PSI. So if you're hauling a fifth wheel or a bed of gravel, you'll just have to crank up the pressure, and then when you're unloaded and heading home, drop that pressure back down for a softer ride. With the manual inflation valves, you're gonna be able to tune your suspension for that day's work very easily. It's gonna be very straightforward.

Now, as you know, extreme hauling demands extreme durability. These springs are built with one inch thick corrosion resistant end caps, which you can't see because I do have them kind of put together here for you. But these are also reinforced with 20 internal support wires giving you maximum strength under that heavy load. These also have heavy duty roll plates on the top and the bottom to help protect the bags from chafing and extend their lifespan. And then the powder coated steel brackets are gonna fight back against rust, road salt and rough seasons.

So no matter the weather or the road conditions, this system is going to hold up for you without any issue. These precision laser cut custom fit brackets are designed to bolt cleanly to your truck's existing mounting points without welding or drilling to your frame. On your screen, I'm including a complete photo of the complete hardware that's gonna be coming with this. So you'll just install this with the included hardware, and your tools and again, not gonna have to worry about any welding or drilling, which is a great benefit that this kit provides. So this kit is designed to work with your setup as it is right now, and then wherever your upgrades are gonna take you tomorrow. Again, you're gonna be able to inflate manually with the standard air valves right out of the box. No extra parts needed. But maybe you already have an onboard compressor. If so, these are gonna connect easily to most existing setups. Or if you're planning for something like an in cap wireless controller down the road, that's not gonna be an issue either, because the foundation is already built in with this kit, making it very easy to expand your control options when you are ready. So again, this is gonna give you up to 7,500 pounds of additional leveling support, but please be aware of the fact that these airbags do not actually increase your truck's weight carrying capacity. So you do wanna make sure that you're not exceeding your manufacturer's recommended weight limit. If you do pick this kit up, we want to hear back from you regarding your experience with getting these installed and using them, so you can share your experiences with us by dropping a comment or leaving a review on this product page. And then if you have any other additional questions, don't hesitate to give us a call, shoot us an email or send us a chat. We wanna make sure that you're getting exactly what you want and need. Well, that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
