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'll take a look at the Pacbrake Alpha HD Air Bag 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 2017 and newer Ford F250, F350, and F450 Super Duty trucks, both two wheel drive and four wheel drive. A couple notes I do wanna mention though, it is compatible with dual rear wheel models without the factory lift blocks, but it will not fit cabin chassis vehicles, 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 model vehicle, and it'll show 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. This kit will include everything I have laid out here on the table. It includes the air springs for the rear axle, both the upper and lower roll plates, the precision laser-cut powder-coated steel mounting brackets, the grade 5 plated hardware, comes with the air lines, with the inflation valves. Right up here, we have the push-to-connect fittings for the air lines to connect to, and it comes with everything else you need for installation and even a set of installation instructions. Now basically, when this trailer is loaded and the bed is full, your truck's gonna need more than just the stock rear springs to stay level and in control.
So these Alpha HD air springs are 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 keeps you from sagging, squatting, and struggling for control. Also, one load isn't like the next. That's why the Pacbrake is gonna give you freedom to adjust your 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. So 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 again, you can start with the simple manual inflation and then you can even expand your system later with onboard air or wireless controls. This Alpha HD system is designed to scale with your setup, making future upgrades easy without having to redo your whole foundation. Now I did wanna zoom in. Now these aren't light duty.
This isn't light duty gear. These Alpha HD springs are built with one-inch thick end caps on each end of the spring. They use 20 internal wires in the spring to handle extreme loads without giving in, and our parts are all corrosion-resistant parts. The roll plates right here are for protection of the spring, and the powder-coated brackets ensure the system will hold up through road salt, rain, mud, and even over time. Now, these precision laser-cut brackets we mentioned, the mounting brackets, they are designed to bolt cleanly to your truck's factory mounting points without any welding or drilling your frame, and one thing to mention is 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. That's gonna do it for a look at the Pacbrake Alpha HD Air Bag Suspension Kit for your rear axle.
