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 Bags Jounce Bumpers - PB57RV

Hi everybody. Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha XD Pro Rear Axle Double Convoluted Airbag Suspension Kit with Internal Jounce Bumpers. Now this kit has been designed to work with your 2019 and newer RAM 3500, both the two and four-wheel drive models, and I do wanna make you aware of the fact that this kit will not fit factory air suspension or cab and chassis vehicles. And 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.

So as you know, when the load gets heavy, your truck is going to need more than just those rear factory springs hanging on for dear life. These airbags are going to add up to 7,500 pounds of rear axle support, keeping your truck level and steady even when your trailer is loaded, the bed is packed and the miles are long. Now you're not gonna have to worry about any more rear end sagging throwing off your braking and steering or your headlights pointing up to the sky because of the heavy load in the back. Bottoming out doesn't feel rough. Not only feel rough, but it can wreck your airbags.

That's why this system includes internal jounce bumpers inside of each bag as I'm showing you there on that photo on your screen. So even with no air pressure, your suspension has a built-in safety net and you can safely run at zero PSI when unloaded, which means no harsh rebound, just that smooth factory style ride. So, as you know, every haul is different. That's why these air springs give you full control over ride height and firmness with adjustable air pressure from five to 100 PSI. So if you're hauling a fifth-wheel or a full bed of gravel, you can load up the pressure to the firmness that's going to work best for you.

And then when you are unloaded and heading home, you can drop that pressure back down for a softer ride. With the manual inflation valves included, tuning your suspension for the day's work is gonna be pretty easy and straightforward. Now, extreme hauling does demand extreme durability. These springs are built with one-inch thick corrosion-resistant end caps that you can't see 'cause I do have these loosely assembled here just to show you what they're gonna look like when you have them installed underneath your vehicle. But the springs also are reinforced with 20 internal support wires for maximum strength under a heavy load.

And then you get these heavy duty roll plates at the top and the bottom, and they're gonna protect the bags from chafing and extend the lifespan. These powder coated steel brackets are going to fight back against rust, road salt, corrosion, and so this kit's going to be able to handle virtually any type of weather, any type of road conditions. Now these precision cut laser, precision laser cut brackets, they're custom fit. They are designed to bolt cleanly to your truck's existing mounting points without welding or drilling your frame. And this kit is designed to work with your setup today and wherever your upgrades are gonna take you tomorrow. You can inflate manually with the standard air valves right now out of the box. No extra parts are gonna be needed. But then if you already have an onboard compressor, this is going to connect pretty easily to most existing setups. And then if you're planning for an in-cab wireless controller down the road, that's not gonna be an issue because with this kit, you're already laying the foundation to expand your control options down the road. So you got all the brackets and hardware that you're going to need with the airline to get this installed into place. Instructions are included to guide you through that installation process. And again, this is gonna give you up to 7,500 pounds of additional leveling support. But be aware of the fact that air springs 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 would love to hear back from you regarding your experience with getting this installed into place and how it's been working out 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 additional questions, don't hesitate to give us a call. We'd love to help you out. 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.
