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 - PB32RV

Hi, everybody, Andy here with etrailer.com. Let's take a 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 2020 and newer Chevy Silverado and GMC Sierra 2500 and 3000s, with both the two-wheel drive or four-wheel drive. And this is going to work with your single rear wheel and dual rear wheel models. Now, if you have an AT4 or Trail Boss model, they do require a 2-inch air springing spacer. And so you want to take a look at the part number that you see there on your screen if you do have the AT4 or the Trail Boss models.

And then this is going to fit all trucks, including those with the OEM fifth-wheel prep packages. This will not, however, fit the Cab and Chassis models, and this will not fit vehicles with the aftermarket Curt fifth-wheel packages. So I know that's a lot of info there for you, that's why I've got it listed there for you on the screen just to be sure that you understand that info. We do have it listed again on this product page as well if you need to revisit those points. But all that to say, this is a custom-fit kit, so it is vital that you go through our vehicle fit guide here at etrailer.com, and put the year, make, and model of your vehicle.

And our fit guide will confirm if this will work for you or if we've got 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 factory leaf springs in the rear hanging on for dear life. These air bags are going to add 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 is going to throw off your braking and steering, and your headlights are not going to point in the sky anymore, but on the road where they belong. Bottoming out doesn't just feel rough, that can actually wreck your bags.

And so that's why this system includes internal jounce bumpers inside each bag. And I got a picture of what that looks like there with that cutaway on your screen. So even with no air pressure, your suspension is going to have a built-in safety net. You're going to be able to run safely at 0 psi when unloaded, which means no harsh rebound, just a smooth factory-style ride. As you know, every haul is different, that's why these airbags give you full control over your 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 that pressure, and then when you're unloaded and heading home, you can drop that pressure back down for a more softer ride. Now, with these manual inflation valves included, tuning your suspension for the day's work is going to be very straightforward. And of course, extreme hauling demands extreme durability, and these springs are built with 1-inch-thick corrosion-resistant end caps. Now, you're not going to be able to see those end caps because they do have this kind of loosely assembled, but the bags are also reinforced with 20 internal support wires from maximum strength under that heavy load. Then we do have these heavy-duty roll plates on the top and bottom. They're going to protect the bags from chafing and extend the lifespan of the bags. These powder-coated custom-fit steel brackets are going to fight back against rust and corrosion. So this entire kit is designed to handle whatever road conditions you encounter in whatever season you're in, they're going to hold up really well for you. These precision laser-cut brackets are designed to actually bolt cleanly to your truck's existing mounting points without welding or drilling to your frame with the included hardware that you see here. So this kit is designed to work with your setup today and wherever your up rates take you tomorrow. Again, you're going to be able to inflate manually with the standard air valves right out of the box, no extra parts needed. But if you already have an onboard compressor, these are going to connect easily to most existing setups. And then if you're planning for like, something like an in-cab wireless controller down the road, that's not going to be an issue because the foundation with this kit is going to already be built in, making it easy for you to expand your control options whenever you are ready. So as I mentioned, this is going to give you up to 7,500 pounds of additional leveling support, but please be aware of the fact that these air springs do not actually increase your truck's weight carrying capacity, so you want to 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 how the installation went and how the operation is going. 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 that I did not answer for you during our time together, don't hesitate to give us a call, we'd love to help you out further. But I think that's going to wrap up our look today, I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
