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.

  • 5,000-lb Load Support: Reduces rear-end sag, sway, and bounce for better handling under load.

  • Adjustable Air Pressure: Set support between 0 psi and 100 psi depending on your load.
  • Complete Kit, Minimal Drilling: Includes laser-cut brackets, push-to-connect fittings, and all hardware.
  • Ready Now, Upgrade Later: Use manual inflation or connect to onboard air when you're ready.

Features to know about

Control and Cushion When It Counts

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.

Comfort When Unloaded, Control When Loaded

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.

Built Tough for Work and Weather

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.

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 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.

Flexible for Today, Ready for What's Next

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.


Want to step up to an all-in-one kit with air bags, compressor, and wireless controller in one package? We've got you covered with Pacbrake's On Demand Kit (PB79YV).


Looking for a complete system with onboard air storage too? Upgrade to one of the "Ultimate" Kits (PB92YV) or (PB42YV) with air bags, compressor, wireless controller, and 1/2-gallon or 2-1/2-gallon air tank for added versatility.

Video Transcript for Review of Pacbrake Vehicle Suspension - Alpha HD Pro Rear Axle Air Bag Kit Jounce Bumpers - PB92ZV

Hi everybody. Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha HD Pro rear axle double convoluted airbag suspension kit with internal jounce bumpers. Now this kit has been designed to fit your 2019 and newer Chevrolet Silverado and GMC Sierra 1500, both the two and four wheel drive models. And this will fit all truck bed lengths. However, this is not going to fit models equipped with the adaptive ride control.

And for the AT4 Trail Boss four wheel drive models, you should use the kit that you see there identified by that number that you see there on your screen, which comes with a required two inch spacer. Now on custom fit parts such as this kit, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Input the year, make and model of your vehicle and our fit guide will confirm if this kit will work for you or if we have something comparable that will work for you. So as you know, 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 5,000 pounds of rear axle support, keeping your truck level and steady even when the trailer is loaded and the bed is packed and the miles are long.

Now with this kit, you're not gonna have to worry about any more rear end sag throwing off your braking or steering or shooting your headlight aim up in the sky rather than being on the road where it should be. Now, bottoming out doesn't just feel rough, it can wreck your airbags. That's why this system includes the internal jounce bumpers inside of each bag. And on your screen, I'm popping up a photo there giving you kind of a cutaway there, showing you what that jounce bumper looks like inside the bag. So this kit will include that internal jounce bumper.

So even with no air pressure, your suspension has a built-in safety net. You're gonna be able to safely run at zero PSI when unloaded, which means no harsh rebound, just that smooth factory style ride. So each haul is different. That's why these air springs are gonna give you full control over your ride height and firmness with adjustable air pressure from five to 100 PSI. So if you're hauling a fifth wheel or a full bed of gravel, you'll just crank up that pressure and then when you're done you can just unload and when you have unloaded your truck or your trailer, you can just let the air out to drop that pressure back so you have a smoother ride.

So the manual inflation valves are included and this is going to be very easy to air up and let the air out. You got the airline as well, so everything's gonna be really straightforward. And of course extreme hauling demands extreme durability. And these springs are built with one inch thick corrosion resistant end caps on either end and you can't see them, those end caps, 'cause I obviously have 'em kinda loosely put together here. The roll plates here are covering them up, but the bags also are reinforced with 20 internal support wires for maximum strength under that heavy load. And then these heavy duty roll plates that I mentioned are going to protect the bags from chafing. They're gonna help extend the lifespan of the bags. And then these custom fit powder coated steel brackets are gonna fight back against rust and corrosion and road salt and rough seasons. So if it's bitter cold or scorching heat or mud slick job sites, this system is gonna be made to outlast whatever the road gives it, mile after mile and load after load. I do wanna say that I have dealt with other airbag suspension kits in the past from other manufacturers and each of them have their own strengths. But when I look at Pacbrake here, the word that comes to mind is a premium, with just how everything is constructed. The materials on the bags themselves that the bags are constructed from are just high quality. And then these brackets have a really great powder coat finish on there that I think is gonna last you a long time. So if you're looking for a premium airbag kit, I would definitely go to Pacbrake, in my opinion, they are the premium option when it comes to airbag suspension kits. These precision laser cut brackets are designed to bolt cleanly to your truck's existing mounting points without welding or drilling to your frame. And so this kit's gonna be designed to work with your setup today, and then wherever your upgrades are gonna take you, it'll follow you through with those upgrades tomorrow, you're gonna be able to inflate 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 like something like an in-cab Wireless controller down the road, that's not gonna be an issue because with this kit, you're already laying down the foundation so that you're gonna be able to expand your control options when you're ready. Again, the load leveling support is 5,000 pounds. I do wanna mention though, that these kits are not designed to actually increase your weight carrying capacity on your truck. So you wanna make 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 installing and using this kit, and you can share your experience with us by dropping a comment or leaving a review on this product page. And if you have any other additional questions, don't hesitate to 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.

Great quality!

So far so good two trips with camper and worked great !



by:

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



by:

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.



by:

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.



by:

First off this is my first experience with air bags. When I was a kid it was air shocks. First, off tip of the hat goes to etrailer for fast delivery. Many times I read reviews where people complain about directions. These people I would guess have very little mechanical skills. The included instructions with these is very comprehensive and thorough. The would make this easy for the average guy. Second, soon as you start to unpack the parts you can tell this is heavy duty well made product. Everything fit perfectly. I gained 3 inch’s at 50 lbs. my build is a b class transit 250 van. 148EL. When you start building these things the weight adds up quick. Was starting to regret not getting a 350 but this saved the day. No miles on it yet but certainly clearance issue is solved,



by:

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,

  • Way To Correct 4 Inches Of Sag In A 2023 Chevrolet Silverado 1500 High Country 4x4 Towing A Boat
    Hi Darrell, congrats on the new boat! The SumoSprings Solo Custom Helper Springs - Rear Axle # SS45FR will indeed help with the sag you are getting. These are a set it and forget it way to go and we have gotten good feedback from others that have gone this route. Plus the install is quick and easy, which is definitely nice. The only drawback to these is that set it and forget it thing. They do not have any adjustments to make them more supportive or less supportive. They work really well...

  • Why Do Some Pacbrake Air Bags Have Internal Jounce Bumper and Firestone Do Not
    Hey Don! The Pacbrake Alpha HD # PB32ZV you were looking at does not have the internal jounce bumper. You would need the Pacbrake Alpha HD Pro Air Bag Suspension w/ Internal Jounce Bumpers # PB92ZV. The jounce bumper adds additional support when you're running the air bags at the minimum psi and an extra layer of protection if you bottom out. Firestone is pretty confident in their bags and they don't see bottoming out as a real concern. I'm not sure why they don't add them in as a backup...

  • Correct Pacbrake Air Bag Kit for a 2024 Chevy Silverado 1500 ZR2
    Hey Zee, thanks for reaching out! The correct Pacbrake Alpha HD Pro Kit for your 2024 Chevy Silverado 1500 ZR2 is the Kit # PB92ZV. This is the same as the Pacbrake part number HP10340-J they have listed on their site. They only have it listed that the AT4 and Trail Boss models need a 2" spacer kit installed so you should be good to go as is! Then to add a compressor kit (if you choose to go that route) we've got the Pacbrake Dual Channel Wireless Air Spring Controls w/ Remote # PB39MV. I...
