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 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.
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.
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 just a few 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.

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha XD rear axle, double convoluted airbag suspension kit. Now this kit has been designed to fit your 2019 and newer RAM 3500, both the two and four-wheel drive models. And I do wanna let you know that this will not fit factory air suspension or cab-and-chassis vehicles. 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 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 the trailer is loaded or the bed is packed and the miles are long. So you're not gonna have to worry about any more rear end sagging throwing off your braking or steering, or your headlights pointing up to the sky. As you know, every haul is different.
That's why these air springs give you full control over the 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 the pressure, and then when you're 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 can be very easy and straightforward. Now extreme hauling does demand extreme durability, and these springs are built with one-inch thick corrosion-resistant end caps, which you can't see because they do have them loosely put together here just to give you an idea of what these are gonna look like when you have them installed. But the bags also are reinforced with 20 internal support wires, giving you that maximum strength under a heavy load.
And then these heavy-duty roll plates on the top and the bottom are going to help protect these bags from chafing and help extend their lifespan. These powder-coated steel brackets are gonna fight back against rust and corrosion. So this kit is equipped and built to endure virtually anything that you're gonna throw at it, any type of season, any type of road conditions. These precision-cut, custom-fit, laser-cut brackets rather are designed to bolt cleanly to your truck's existing mounting points without welding or drilling to your frame with the included hardware that you see here. And this kit is designed to work with your setup today and wherever your upgrades take you tomorrow.
You're gonna be able to inflate manually with the standard air valves right out of the box. No extra parts are gonna be needed. But if you already have an onboard compressor, this is going to connect 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 you're building the foundation right now with this kit, so you're gonna be able to expand your control options when you're ready. So again, the load support is gonna be up to 7,500 pounds, but do be aware of the fact that these airbags do not actually increase your truck's weight carrying capacity. So you wanna be 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 the installation and operation of this kit, and you can do that by dropping a comment or leaving a review on this product page. And if you have any additional questions that I did not cover for you today, don't hesitate to give us a call. We'd love to help you out further. 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.
