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 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 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 the Pacbrake Alpha HD Airbag Suspension Kit for your rear axle, has a 5,000 pound load leveling capacity. Now this is a custom fit part. It is designed to fit the 2005 to 2010 Ford F-250 and F-350 4-wheel drive super duty trucks. Now this is for all trucks, including those that even have fifth wheel hitches, but it is not for commercial cabin chassis trucks. 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 if this works for your application.
Now these airbags 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 your rear axle, the upper and lower roll plates, the precision laser cut powder coated steel mounting brackets. All the grade five plated hardware comes with the air lines with the inflation valves. Up here we have installed on the springs the push to connect fittings for the air lines to connect to, and it comes with a set of installation instructions that'll describe how this all goes together.
Basically, when your trailers load it and the bed is full, your truck's gonna need more than just the stock rear springs to stay level and in control. That's where the Alpha HD air springs like these will come into play. 'Cause they're gonna 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 is gonna keep you from sagging, squatting, and struggling for control. And also, one load isn't like the next.
That's why this pack brake 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, you just pump it up. If you're unloaded, heading home, you drop the pressure for a lot smoother ride. So 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. So basically, you can start with the simple manual inflation and then you can expand the system later with onboard air or wireless controls.
This Alpha HD system is designed to scale with your setup, so it makes future upgrades easy without having to redo the whole foundation. Now I did wanna zoom in and show you up close. These aren't light duty. This isn't light duty gear. These Alpha HD springs right here are built with one inch thick end caps on each spring. And then in each spring they use 20 internal wires to handle extreme loads without giving in. All the parts are corrosion-resistant parts. The roll plates we mentioned right here, the upper and the lower roll plates, these are designed for protect the air springs and the powder coated brackets will ensure that this system holds up through road salt, rain, mud, and even over time. Now, the precision laser cut brackets we mentioned, they are designed to bolt cleanly to your truck's factory mounting points without welding or drilling your frame. And these 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. But that's gonna do it for a look at the Pacbrake Alpha HD Airbag Suspension Kit for your rear axle.
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!
