7,500-lb Capacity. When your truck or van squats under weight, steering gets light and control fades. These extreme-duty air bags level your ride, help keep you in control, and protect your suspension from the punishment of heavy loads.
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.
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.
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.
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.
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.
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.

Hello, everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the PacBrake Alpha XD Pro Airbag Suspension Kit for your rear axle. It has a 7,500 pound load leveling capacity. Now, this is a custom-fit part, it is designed to fit the 2018 and newer Ram 4500 and 5500 cabin chassis trucks, and it will work either two-wheel drive or four-wheel drive models. Now, on a custom-fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show if this will work for your application. Now, when your load gets heavy, your truck's gonna need more than just the rear springs hanging on for dear life, and that's where these Alpha XD Pro Air Springs will come into play, 'cause they're going to add up to 7,500 pounds of rear axle support, keeping your Ram level, steady, and confident, even when the trailer is loaded, your bed is packed, and the miles are long.
So there's no more rear end sag that's throwing off your braking and steering, or your headlights pointing up into the sky. Basically, with this airbag support underneath, you're gonna keep control of your ride, your cargo, and have peace of mind even when you're towing a serious payload. This part will include everything I have laid out here on the table, includes the air springs for the rear axle, the upper and lower roll plates, the precision laser cut powder coated steel mounting brackets, all the Grade 5 plated hardware, and then the airlines, right over here with the inflation valves. And we've already installed on the springs, but they have the push-to-connect fittings that your airlines will connect to. It does come with a nice set of installation instructions here that'll describe how this all goes together.
Now, bottoming out doesn't just feel rough, it can also wreck your airbags, that's why this XD Pro system includes the jounce bumpers that are on the inside of each Air Spring. So even with no air pressure, your suspension still has a built in safety net. Basically what that does is it allows you to safely run at zero PSI when you're unloaded, which means no harsh rebound, just a nice, smooth factory-style ride. And also 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 nice quick bump in pressure. And as you know, every haul is different, that's why the Alpha XD Pro Air Springs are gonna give you full control over your ride height and firmness with an adjustable air pressure from 5 to 100 PSI.
So, basically, if you're hauling a fifth wheel or a full bed of gravel, you just crank up the pressure. If you're unloaded and heading home, just drop it back down for a smoother ride. With the manual inflation valves included, turn-tuning your suspension for the day's work is pretty straightforward. Now also, heavy hauling does demand extreme durability. I did wanna zoom in and show you right here, these Alpha XD Pro Springs are built with one-inch thick corrosion resistant end caps, and then they are reinforced with 20 internal support wires for maximum strength underload.
The roll plates we mentioned, the upper and lower roll plates here, these will protect the air springs from chafing and extend the lifespan. And as we mentioned, this is the pro series, so it does include the jounce bumpers on the inside of the springs. Now the powder coated steel mounting brackets do fight back against rusted road salt, and they are precision laser cut brackets, so they are designed to bolt cleanly to your truck's existing mounting points without any welding or drilling your frame, just smart engineering that fits the way it should, which is perfect for a do-it-yourselfer. The manual valves right here that are on the airlines, these will mount through your license plate fastener holes or a location of your choosing. And with the high-quality fittings, the pre-bent brackets, and your mounting hardware all included, you're gonna be back on the road with a nice stronger, steadier truck in just a few hours without a trip to have 'em go to a shop to put 'em on. Now we mentioned it has the valves up here that your airlines will connect to, so you can inflate manually with standard air valves right out of the box, no extra parts needed. And if you already have an onboard compressor, this Alpha XD Pro system will connect easily to most existing setups. But if you're planning for an in-cab wireless controller down the road, no problem, the foundation's already built in, just to make this easy to expand your control options when you're ready. One note I do wanna mention on this, these air springs will not increase your vehicle's weight carrying capacity, so you do not want to exceed the manufacturer's recommended weight limit. But that's gonna do it for a look at the PacBrake Alpha XD Pro Airbag Suspension Kit for your rear axle.
