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 Air Bag Suspension Kit with the internal jounce bumpers for your rear axle. It has a 7,500 pound load leveling capacity. Now this kit is a custom fit part. It is designed to fit the 2011 to 2019 Chevrolet Silverado and the GMC Sierra 2,500 HD and 3,500 HD trucks, two wheel drive or four wheel drive. Now this will fit trucks with or without fifth wheel hitches, but it will not fit cabin chassis vehicles.
And 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 you if this will work for your application. Now these airbags are gonna help you stay level, drive steady, and stay in control when you're hauling heavy loads. The kit will include everything I got laid out here on the table. It includes the air springs for the rear axle, the upper and lower roll plates, all the precision laser cut, powder coated steel brackets, the grade five plated hardware, the air lines, and all the push to connect fittings and inflation valves, and also a nice set of installation instructions. Now, basically when your trailer's loaded and the bed is full, your Silverado or your Sierra's gonna need more than the stock leaf springs to stay level and in control.
And these Alpha XD Pro Air Springs will add up to 7,500 pounds of rear axle support, helping your truck stay steady and secure through every haul. Now, whether you're pulling a fifth wheel, hauling materials or towing equipment, this upgrade will keep you from sagging, squatting, and struggling for control. Also, what's nice with this kit, the XD Pro Kit, bottoming out doesn't just feel rough anymore, it could wreck your airbags, so with this kit, this includes the jounce bumpers, which are on the inside of each air spring. So even if there's no air pressure in the spring, your suspension's gonna have a built-in safety net. You could basically safely run it zero PSI when unloaded, which means no harsh rebound.
Just a nice smooth factory style ride. And also one load isn't like the next. So that's why this Pacbrake will give you freedom to adjust your air pressure from five to a hundred PSI. So if you need full support for a loaded trailer, just pump it up. If it's unloaded, heading home, just drop the pressure for a lot smoother (indistinct) ride.
And also with the simple manual inflation right out of the box, you get better ride quality and confidence no matter how much you're hauling. Now also what's nice is this isn't a light duty gear. This Alpha XD Pro Springs are built with one inch thick end caps on the springs, and the spring itself has 20 internal wires to handle extreme loads without giving in. Also, the parts being corrosion resistant, the roll plates for protection, and the powder coated brackets ensure this system is gonna hold up through road, salt, rain, mud, and even time. Now this kit is designed to hold to factory mounting points on your Silverado or Sierra. The air spring kit installs with no frame drilling required. You just start with a manual inflation, or you can even expand this kit later with an onboard air to wireless controls. Now this Alpha XD Pro's designed to scale with your setup, so making future upgrades easy without redoing the foundation. One note I do wanna mention is these air springs will not increase your vehicle's weight carrying capacity. So you do want to make sure do not exceed the manufacturer's recommended weight limit. But that's gonna do it for our look at the Pacbrake Alpha XD Pro Air Bag Suspension Kit with the internal jounce bumpers for your rear axle.
