5,000-lb Capacity. When the load gets heavy, your truck shouldn't feel like it's fighting you. These air bags help you stay level and in control so you can tow with confidence and handle heavy loads without second-guessing your suspension.
Heavy trailers, full beds, gear piled high, it all changes how your truck handles. Without the right support, you feel it immediately: sagging in the rear, poor handling, and a ride that gets unpredictable fast. This air bag system puts you back in control with up to 5,000 lbs of load-leveling support it helps reduce squat, improve steering response, and keep your truck stable when the weight stacks up.
Every haul is different, and your suspension should keep up. Alpha HD Pro air springs give you full control over ride height and firmness with adjustable air pressure from 5 to 100 psi. Driving unloaded? The built-in jounce bumpers let you safely run at 0 psi for a smooth, factory-style ride with no harsh rebound. Hooked up to a fifth wheel or hauling a bed full of gravel? Add air to level the truck and keep handling tight. With manual inflation valves included, tuning your suspension for the day's load is straightforward and dependable.
Air bags are only as strong as their weakest link. That's why Alpha HD Pro bags are reinforced all the way through with heavy-duty end caps, 20 internal support wires, integrated jounce bumpers, and powder-coated steel brackets. Toss in corrosion-resistant hardware and thick roll plates, and you've got gear that holds up to real-world hauling through heat, cold, salt, and slop.
Adding serious load support shouldn't mean losing a whole weekend. The precision laser-cut brackets are designed to bolt cleanly to your truck's existing mounting points with minimal drilling. Just smart engineering that fits the way it should which is perfect for the DIY-er. 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. You can inflate manually with standard air valves right out of the box, no extra parts needed. Already have an onboard compressor? The Alpha HD Pro system connects easily to most existing setups. Planning for an in-cab wireless controller down the road? No problem. The foundation is already 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 this Pacbrake Alpha HD Pro airbag suspension kit with the internal jounce bumpers for your rear axle. Has a 5,000-pound load leveling capacity. Now this is a universal kit that'll fit many but not all of your early model Dodge, Ford, and GM trucks. And to make sure it'll fit your application, what I would recommend is go to our website, use the fit guide, put in your year ad model vehicle, and it'll show if this will work for your application.
Now these airbags here are gonna help you stay level, drive steady, and stay in control when you're hauling heavy loads. It will include everything I have laid out here on the table. It includes the air springs for the rear axle, the upper and lower roll plates, precision laser-cut powder-coated steel brackets, a grade five plated hardware, comes with the airlines with the inflation valves. Up here we've installed the push to connect fittings for your airlines to connect to. And it does come with installation instructions that'll describe how this all goes together.
Basically, when the trailer is loaded and the bed is full, your truck needs more than just your stock rear springs to stay level and in control. That's where these Alpha HD Pro air springs will add up to 5,000 pounds of rear axle support, helping your truck stay steady and secure through every haul. So whether you're pulling a fifth wheel, hauling materials, or towing equipment, this upgrade's gonna keep you from sagging, squatting, and struggling for control. Also, with this kit, the bottoming out doesn't just feel rough, it could wreck your air springs. That's why this system includes jounce bumpers that are on the inside of each spring.
So even with no air pressure, your suspension has a built-in safety net. You could safely run at zero PSI when you're unloaded, which means no harsh rebound, just that smooth factory style ride. Also, one load isn't like the next. That's why the Pacbrake gives you the freedom to adjust the air pressure from five to 100 PSI. So basically, if you need full support for a loaded trailer, just pump it up.
If you're unloaded, heading home, drop the pressure for a smoother ride. Basically, with the simple manual inflation right out of the box, you're gonna get better ride quality and confidence no matter how much you're hauling. And since you'll just start with the manual inflation, you could expand the system later with onboard or wireless controls. Now this Alpha HD Pro is designed to scale with your setup, making future upgrades easy without redoing the foundation. Now, also, I want to zoom in to show you this isn't just light duty gear. These Alpha HD Pro springs are built with one-inch thick end caps on each spring, and they use the 20 internal wires to handle extreme loads without giving in. They use corrosion-resistant parts. The roll plates we mentioned, that'll give the springs protection. And then the powder-coated brackets will ensure that this system hold up through road salt, rain, mud, and even over time. Now, this is a drill to fit installation. It includes, as we mentioned, the brackets and the hardware for a clean install on your older frames. Now the air springs will not increase your vehicle's weight carrying capacity, so you do wanna make sure not to exceed the manufacturer's recommended weight limit. And that's gonna do it for a look at the Pacbrake Alpha HD Pro airbag suspension kit with the internal jounce bumpers for your rear axle.
Easy to install and looks like it’s a high-quality product
The brackets are not built heavy enough
good product , good strong solid metal parts and heavy bags. The instructions were not so hot but was easy to figure out and quick delivery !
Easy install. Will pull trailer 3000 miles on vacation and see how it performs to Montana on highways and Forest Service roads.
Where to start I have 1500 pounds of tools in my 150 Chevy had them installed and it totally changed the ride and handling of the truck haven’t pulled anything yet but I’m amazed on how different the truck is already I Baught the ones with the bump stops in them the HD ones
I'm Vincent J,
My experience with loading my truck and seeing the difference with these air bags from PacBrake, it does look way better and the truck feels a bit more stable running atspeed limit (65mph) after that it does feels jumpy if you go over potholes, but overall I'm happy with the product, thanks Etrailer,
2020 Ram 1500.
Installation is fidgety with lining everything together for the upper bracket with u-bolt(reason for 4 stars), but still preferred over cutting the bump stop mounts off. Replaced the Timbrens with this and it is night and day difference in ride quality both unloaded and towing.
Would purchase again.
Product is well constructed and installation is straightforward. But you cannot build the kit and slip it in, you have to leave the top bracket off and install it after setting the lower bracket and air bag in place. I will note, I was working off jack stands and a floor jack, not on a lift.
haven't received or used it yet but pretty darn excited
