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 grow with your upgrades tomorrow. You can inflate manually through the included 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.

Hello everybody, this is Jeff at etrailer.com. Today we take a look at the Pacbrake Alpha HD Pro Air Bag Suspension Kit. Has the internal jounce bumpers and this is for your rear axle. Has a 5,000-pound load leveling capacity. Now this kit is a custom fit part. It is designed to fit the 2011 to 2019 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD trucks, either two-wheel drive or a four-wheel drive.
It will also fit trucks with or without 5th wheel hitches, but it will not fit cab and chassis vehicles. Now this is a custom fit part, so I do recommend for you to go to our website, use the fit guide, put in your year and model vehicle. 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.
The air springs for the rear axle, the upper and lower roll plates, precision laser cut powder coated steel brackets. All the grade 5 plated hardware, comes with the air lines, the push-to-connect fittings inflation valves, installation instructions, everything you need to put it all together. Now, basically, when your trailer's loaded, the bed is full, your Silverado or your Sierra's gonna need more than just the stock leaf springs to stay level and in control. These Alpha HD Pro Air Springs are gonna add up to 5,000 pounds of rear axle support, helping your truck stay steady and secure through every haul. Now, whether you're pulling a 5th wheel hauling materials or towing equipment, this upgrade's gonna keep you from sagging, squatting, and struggling for control.
Now, bottoming out doesn't just feel rough, it could wreck your airbags, and that's why this system here, we mentioned includes the jounce bumpers that are inside each one of these air springs. So even if there's no air pressure, your suspension still has a built-in safety net. So you can safely run at zero psi when it's unloaded, which means no harsh rebound, just a nice smooth factory style ride. Now, one load also isn't like the next. So that's why this Pacbrake gives you the freedom to adjust your air pressure from 5 to 100 psi.
So basically, if you need full support for our loaded trailer, just pump it up. If you're unloaded heading home, drop the pressure for a slot smoother ride. So with a simple manual inflation right outta the box, you're gonna get better ride quality and confidence no matter how much you're hauling. Now also, let me just zoom in here, this isn't light duty gear. This Alpha HD Pro Springs are built with 1-inch thick end caps on the end of each spring, and they use 20 internal wires in the spring to handle extreme loads without giving in. They also use corrosion-resistant parts, roll plates for protection of the springs, and powder coated brackets to ensure the system will hold up through road salt, rain, mud, and even time. This kit is designed to bolt the factory mounting points on your Silverado or Sierra. This air springing kit installs with no frame drilling required. And basically, you'll start with manual inflation or you could even expand your system later with an onboard air or wireless controls. This Alpha HD Pro system is designed to scale with your setup, so it makes future upgrades very easy without having to redo the foundation. One thing I do wanna mention is these Air Springs will not increase your vehicle's weight tear and capacity, so you do wanna make sure not to exceed the vehicle's recommended weight limit. But that's gonna do it for a look at the Pacbrake Alpha HD Pro Air Bag Suspension Kit with the internal jounce bumpers for your rear axle.
Easy to install and looks like it’s a high-quality product
haven't received or used it yet but pretty darn excited
The brackets are not built heavy enough
Easy install. Will pull trailer 3000 miles on vacation and see how it performs to Montana on highways and Forest Service roads.
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 !
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.
