Features to know about

Built to Handle Serious Loads and Keep You in Control

When your truck or van carries 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. Each air spring also includes an internal jounce bumper that cushions your suspension if air pressure drops, helping protect your ride and frame from bottoming out.

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.

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. If you're heading to work with an empty bed or cruising home after dropping the trailer, your truck stays comfortable, controlled, and ready to haul again with just a quick bump in pressure.

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 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 Pro Rear Axle Air Bag Kit Jounce Bumpers - PB99RV

Hi everybody, Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha XD Pro, Rear Axle, Double Convoluted Air Bag Suspension Kit with Internal Jounce Bumpers. Now, this kit has been designed to fit your 2011 to 2016 Ford F-250 and F-350 Super Duties, either with a two or a four-wheel-drive. This will also work with your 2011 to 2014 F-450 Super Duty. Again, with either the two or four-wheel-drive. And I do wanna point out, as you see there on your screen, this will fit models with or without a fifth wheel hitch.

So on 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 your load gets heavy, your truck is gonna need more than just those factory rear springs hanging on for dear life. These air bags are going to give you up to 7,500 pounds of rear axle support, keeping your truck level and steady even when your trailer is loaded and the bed is packed and the miles are long. Now, you're not gonna have to worry about any more rear-end sag throwing off your braking and steering or your headlights pointing up to the sky.

Now, as you know, bottoming out just doesn't feel rough, it can indeed wreck your air bags. That's why these springs include internal jounce bumpers inside of each bag, as you can see on that cutaway there. So even with no air pressure, your suspension has a built-in safety net. So because of those internal jounce bumpers, you can safely run at zero psi when unloaded, which means no harsh rebound, just that smooth factory-style ride. If you're heading to work with an empty bed or cruising home after dropping the trailer, your truck's gonna stay comfortable, controlled, and ready to haul again with just a quick bump in the pressure.

And of course, every haul is 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 crank up the pressure, and then when you're unloaded and heading home, you can drop it back down for a more softer ride. The manual inflation valves are included. Tuning your suspension for the day's work is gonna be very easy, very straightforward.

Extreme hauling does demand extreme durability. These springs are built with one inch thick corrosion-resistant end caps that you can't see 'cause they do kind of have them loosely assembled here. But the bags are also reinforced with 20 internal support wires for maximum strength under that heavy load. And then at the top and the bottom here, we have these heavy-duty roll plates that are gonna protect the bags from chafing and help extend their lifespan. These powder-coated steel, custom fit brackets are gonna fight back against rust, corrosion, so these are gonna be able to handle any type of weather or road conditions. These precision laser-cut brackets are designed to bolt cleanly to your truck's existing mounting points without welding or drilling to your frame. Now, I don't have it on my table here, but I am showing you a picture of all of the hardware that's going to be included with this kit. So like I said, you're not gonna have to worry about welding or drilling. You're just going to install this with the hardware that you see there and just supply your tools, and it's going to be good to go. So this kit is designed to work with your setup today or wherever your upgrades are gonna take you tomorrow. 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. If you do, that's great because these are gonna connect easily to most existing setups. And then maybe you're planning for something like an in-cab wireless controller down the road. That's not gonna be an issue with this kit because you're laying the foundation. The foundation's gonna already be built-in, making it very easy to expand your control options when you're ready. So as I mentioned, the load support is up to 7,500 pounds, but do be aware of the fact that these do not increase your weight-carrying capacity on your truck, so you wanna make sure that you're not exceeding the manufacturer's recommended weight limit. If you do pick this kit up, we wanna hear back from you regarding how the installation went and how the operation of this kit is going for you. 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, do not hesitate to reach back out to us, either by phone, email, or chat. We wanna make sure that you're getting exactly what you want and need. Well, that's gonna wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy. Thanks for joining me.
