Features to know about

Built to Handle Serious Loads and Keep You in Control

When your truck or van is built to carry 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.

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.

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 just a few 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 Towing/Load Leveling Kit - PB47RV

Hello, everybody, this is Jeff at etrailer.com. Today we're going to take a look at the Pacbrake Alpha XD airbag suspension kit for your rear axle. 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 cab and chassis trucks, and it will work on either the two-wheel drive or four-wheel drive models. And on a custom fit part like this one, 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 you if this will work for your application.

Basically, when the load gets heavy, your truck is going to need more than just your rear springs hanging on for dear life, and that's where this Alpha XD air spring system will add up to 7,500 pounds of rear axle support, keeping your Ram level, steady, and confident, even when the trailer is loaded, the bed is packed, or the miles are long. There's no more rear end sag throwing off your braking and steering or your headlights pointing up into the sky. And this kit will include everything I have laid out here on the table. It includes the air springs for the rear axle, both the upper and lower roll plates, offers the precision laser-cut, powder-coated steel mounting brackets. Up here we have the grade 5 plated hardware, the airlines with the inflation valves.

Right up here, we've installed to the bags the push-to-connect fittings that your airlines will connect to. And it even comes with a nice set of installation instructions. It'll describe how this all goes together. Now, every haul is different. That's why this Alpha XD air springs will give you your full control over ride height and firmness with the adjustable air pressure from 5 to 100 psi.

So basically, if you're hauling a fifth wheel or a full bed of gravel, you can crank up the pressure. If you're unloaded and heading home, just drop it back down for a lot softer ride. So with the manual inflation valves included right here, tuning your suspension for the day's work is pretty straightforward. And also, as you know, heavy hauling demands extreme durability. So these springs right here, I just want to zoom in a little bit more.

These Alpha XD springs, they are built with 1-inch thick corrosion-resistant end caps on each end, and they are reinforced with 20 internal support wires for maximum strength under load. We mentioned the roll plates, the upper and lower roll plates. These roll plates will protect those air springs from any chafing and extend the lifespan. And the powder-coated steel mounting brackets will fight back against rust and road salt. Now, these precision laser-cut brackets, they are designed to bolt cleanly to your truck's existing mounting points without any welding or drilling your frame. Just smart engineering that'll fit the way it should, which is perfect for the do-it-yourselfer. The manual valves we mentioned, these will mount through your license plate fastener holes or a location of your choosing. And they use high-quality fittings, pre-bent brackets, and the mounting hardware is all included. So you're going to be back on the road with a stronger, steadier truck in just a few hours without having a trip to a shop. Now, as we mentioned, you can inflate these manually with standard air valves right out of the box, no extra parts needed. But if you already have an onboard compressor, this Alpha XD system will connect easily to most existing setups, or even if you're planning for an in-cab, wireless controller down the road, no problem, foundation is already built in, so you're making it easy to expand your control options when you're ready. One last thing I do want to mention is these air springs will not increase your vehicle's weight-carrying capacity, so you do want to make sure not to exceed the manufacturer's recommended weight limit. But that's going to do it for our look at the Pacbrake Alpha XD airbag suspension kit for your rear axle.

  • Availability of 7,500 lb Air Bag Kit for 2024 Ram 5500
    Hey Mike, we do have a Pacbrake air bag solution for your 2024 Ram 5500 but that's only brand we carry that has air bags rated that high. For that you'd want the part # PB47RV or if you want a set that have a jounce spring built in as well we have the part # PB67RV. Were you wanting a compressor kit too? Air Lift has kits too but they are only rated for 5k like the part # AL88255.
