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 Rear Axle Double Convoluted Air Bag Kit - PB85FV

Hi, everybody, Andy here with etrailer.com. Let's take a look at this Pacbrake Alpha XD rear axle double convoluted air bag suspension kit. Now this kit has been designed to fit your 2013 to 2018 RAM 2500 and 3500 and the Mega Cab models. I do wanna point out that this will also be compatible with the 3349 and the 3319 Super Glide fifth wheel rail kits on the 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.

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. This kit is going to add up to 7,500 pounds of rear axle support. So this is going to help keep your truck level and steady. Even when the trailer is loaded, the bed is packed and the miles are long, so you're not gonna have to worry about rear end sag throwing off your braking and steering or your headlights pointing up to the sky. Now as you know, every haul is different.

That's why these springs give you full control over ride height and firmness, with adjustable air pressure from 5 to 100 PSI. If you're hauling a fifth wheel or a full bed of gravel, you'll just crank up the air pressure. And then if you're unloaded and heading home, you can drop that pressure back down, giving you a softer ride. Manual inflation valves are included. And I'm gonna turn this one, just so you can see the bracket there is blocking that.

So you're gonna be able to, right out the box, manually inflate these or let air out, depending on what your particular application's going to be for that particular circumstance. And extreme hauling does demand extreme durability. So these springs are built with one inch thick, corrosion-resistant end caps. You're not gonna be able to see that because I do have these kind of loosely assembled to kind of give you an idea of what this is going to look like when this is installed underneath your truck. But the bags also feature 20 internal support wires that are gonna reinforce these and give you maximum strength under that load.

And then we have these heavy-duty roll plates here on either end that's going to actually protect the bags from chafing and help extend the lifespan of the bags. These custom-fit brackets are powder-coated, and so that's gonna help fight off corrosion and rust and road salt, and they're gonna be great for all seasons. And so if it's bitter cold or if it's a scorching heat or mud lake job sites, the system is made to outlast whatever the road is going to dish out for you. And I will say I have been able to come in contact with other manufacturers' air bag kits. And this kit from Pacbrake has to be the most premium that I've ever seen, with just a great powder-coat finish on the brackets and just the great materials that the bags are made of. I would say that this is probably top-of-the-line when it comes to air bag suspension kit. So this is really gonna be a great, robust, very durable kit for you to consider. These brackets are laser cut, so they are designed to bolt cleanly to your truck's existing mounting points without welding or drilling your frame. So this kit is designed to work with your setup as it sits today or wherever your upgrades are gonna take you down the road. You're gonna be able to inflate, as I mentioned, 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 gonna 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 laying the foundation with this kit. And so it's gonna be very easy to expand your control options when you're ready. So it does include everything that you see here on my table here. You're gonna get the hardware, you will receive instructions to walk you through the installation process. And again, the load leveling support is 7,500 pounds. But just be aware that this does not actually increase your truck's weight carrying capacity. This only supports it. So you wanna be 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, so you can share your experience with us by dropping a comment or leaving a review on this product page. Let us know how the installation went. If you have any questions, give us a call. 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.
