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 Double Convoluted Air Bag Jounce - PB25FV

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 fit your 2013 to 2018 Ram 2500 and 3500 and Mega Cab, and this is compatible with the 3349 and the 3319 SuperGlide fifth wheel rail kits on four wheel drive models only. Now 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 the rear 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. So no more rear end sag throwing off your braking and steering or headlights pointing up into the sky. Now bottoming out doesn't just feel rough, it could actually wreck your airbags. 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 so you can safely run at zero PSI when unloaded, which means no harsh rebound, just that smooth factory style ride.

And every haul is different. That's why these springs give you full control over your ride height and firmness with adjustable air pressure from five to 100 PSI. So hauling a fifth wheel or a full bed of gravel, all you gotta do is crank up the air pressure in these bags, and then when you're unloaded and heading home, you can release the pressure and back it down for a softer ride. With the manual inflation valves, and let me turn this one around just so you can see it, the bracket's hiding it, with these valves included, you can tune your suspension for whatever you're going to need that particular day. So extreme hauling demands extreme durability.

These springs are built with one inch thick corrosion resistant end caps, which you can't see because of these roll plates. But I do kind of have these loosely assembled here just to kind of give you an idea of how everything's gonna go together and what it's gonna look like underneath your truck. It's also been reinforced with 20 internal support wires for maximum strength under a load. And then these heavy duty roll plates on the top and the bottom, they're going to protect the bags from chafing and help extend their lifespan. These brackets are powder coated, so they're gonna fight back against rust, corrosion, road salt in rough seasons.

So if it's bitter cold or if you're driving through a scorching hot day or a mud slick job site, this system is made to outlast whatever the road is going to give you mile after mile and load after load. And I have dealt with other manufacturer's airbag kits, and this, in my opinion, is one of the best kits that I've seen in regards to the build quality, the fit and finish, the materials with the airbags, and the powder coating on the brackets themselves. They just speak of high quality, very premium materials that I think are gonna last you a long time. Very durable, very robust, and I'm very impressed with the build quality. These precision laser cut brackets are going to be designed to bolt cleanly to your truck's existing mounting points. You're not gonna have to worry about welding or drilling into your frame. And this kit is designed to work with what you've got going on today on your truck. Wherever your upgrades take you tomorrow, this is gonna work as well. But out of the box, you're gonna be able to inflate these manually with the standard air valves. And you're not gonna need any extra parts. But if you already have an onboard compressor, these are gonna connect easily to most existing setups. But if you're planning for an in-cab wireless controller, let's say, down the road, that's not gonna be an issue because the foundation is already built in with this kit. So it's gonna be easy to expand your control options when you're ready. So this includes everything that you see here on my table before me, the hardware, the brackets, the airline, everything that you're gonna need to get this installed along with instructions. Again, the load support is up to 7,500 pounds, but this does not actually increase the weight capacity of your truck. So you do wanna make sure that you're not exceeding your manufacturer's recommended weight limit. If you do pick this up, we would love to hear back from you regarding your experience with getting this installed and using them so you can share your experience with us by dropping a comment or leaving a review on this product page. If you have any other additional questions that I did not answer for you today, feel free to give us a call as well. 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.
