Arrives before Christmas To see if this custom-fit item will work for you please tell us what vehicle you'll use it with.
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.
When the load gets heavy, your truck needs more than just rear springs hanging on for dear life. Alpha HD air springs add up to 5,000 lbs of rear axle support, keeping your truck steady even when the trailer is loaded, the bed is packed, and the miles are long. No more rear-end sag throwing off your braking and steering, or headlights pointing into the sky. With air bag support underneath, you keep control of your ride even when you're towing a travel trailer or moving a serious payload.
Every load is different, and this system adjusts to match. Alpha HD air springs let you fine-tune ride height and firmness with air pressure from 5 to 100 psi. 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 inflation valves are included, so tuning your setup for each trip is straightforward and dependable.
Air bags are only as strong as their weakest link. That's why Alpha HD bags are reinforced from end to end with heavy-duty end caps, 20 internal support wires, and powder-coated steel brackets. Add 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 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.
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 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 (PB59YV).
Looking for a complete system with onboard air storage too? Upgrade to one of the "Ultimate" Kits (PB55YV) or (PB35YV) with air bags, compressor, wireless controller, and a 1/2-gallon or 2-1/2-gallon tank for added versatility.

Hi, everyone. Steve here with etrailer.com. Today we're looking at our Pacbrake Alpha HD Airbag Suspension Kit. It's a single convoluted rear axle system rated at 5,000 pounds. Now, folks, this is a custom fit application. Make sure you're checking our fit guide here at etrailer.com to be sure you're getting the right parts for your specific setup.
Now, as you can see, I just have the main bags and the brackets assembled loosely here today. You're gonna get everything in the photo on the screen included. So, all the hardware, all the air line. That's a push-to-connect fittings. The air line tube cutter tool.
All your nuts, bolts, washer, the laser cut brackets. Everything here is a complete kit. Again, right now I just have all this on the table just for viewing purposes. Now, this is a no drill application because everything's been measured, laser cutted, everything from the factory. This is gonna be a pretty straightforward install.
It's gonna take a little bit of time, so I don't wanna lie to you and make it sound like it's gonna be a 30-minute install. We have some videos of installation on some of these vehicles as well that might help you out. You can call, chat, email us if you have questions about this kit, how to install it, is it gonna work for your application, those kinda things. We also carry the same setup with an internal jounce, sold separately. That's a different system.
But it would have an internal jounce stopper inside the bag that you can't see or anything. And that's an option maybe if you have a lot of heavy duty things in the rear of your truck at all times. Maybe a camper all the time or lots of heavy tools and gear, and that kind of stuff. That may be a better option for you. But these are gonna do just great. 5,000 pounds of load support. They're gonna improve ride stability, reduce rear end sag, sway, and bounce, giving you a much smoother ride and better handling. So, maybe you're squatting the back and your headlights are pointing up to the sky. These will get you back level, more tracks and evenly distributed in your headlights pointing in a safe direction. You could adjust the air manually between 5 to 100 PSI, depending on your specific load. And you can purchase separately or upgrade in the future to an onboard air system as well. Well, folks, that is gonna wrap it up for our quick look together. I'm Steven. Thanks for watching.
Don’t fit, worked on it for hours with no luck.
They need instructions to be more clear but fit very nicely i would recommend pacebrake
Going camping!!!
Worked out great
Thank you Joshua for your assistance.
Easy install and done exactly what I needed it to do
Excellent choice… Very high-quality… Took 4 to 5 hours to install… Which included new shocks getting all the tools together and clean up… Very happy thank you
Installed this past weekend. Haven't towed with it yet. Nice construction and finish. I have a 2025 Chevrolet Trail Boss 2500HD and the spacers are NOT needed. Measurement for needing the spacers in 7" and above between jounce cup and contact pad. My space was 5.5" to 6".
Awesome product easy to install and I really appreciate etrailer service
It was very easy install . The ride has improved a lot while towing my 41 ft. toy hauler , Thanks !!
Direct bolt on, plug and play
The product is a great product. After installation was completed and the air added to the air suspension, it raised the rear end of the van about 2-3 inches.A very nice improvement.
Installation instructions definitely need better quality diagrams.
Easy to install and work just as I had expected. Great finish on brackets and quality hardware. Easy to follow instructions. Highly recommend these airbags!
The 2" spacers are definitely not needed for a Trail Boss. I could barely get them in, and now the ride is super stiff. Now I have to get back under the truck and remove the spacers. Not looking forward to that. It was very difficult installation, for no reason.
Very well built brackets, installation was as explained in the instruction. Happy Camper!
Put about 1800 miles on these last weekend. Was picking up a car that's heavier than my normal race car on the ramp truck, so I wanted to give the truck a bit of help. Good news, it worked well. Truck rode beautifully, loaded or unloaded.
The instructions could be a bit more clear, in regards to the clinch stud. I had that on backwards at first because of how things appeared in the picture. Also, I know most things are DIY but installation was about 80% assembly, 20% actual install. If these came already assembled, it would have saved a lot of time!
