Features to know about

Control and Cushion When It Counts

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.

Dial in the Ride for Any Load

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.

Built Tough for Work and Weather

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.

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 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.

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 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 (PB57YV).


Looking for a complete system with onboard air storage too? Upgrade to one of the "Ultimate" Kits (PB58YV) or (PB38YV) with air bags, compressor, wireless controller, and a 1/2-gallon or 2-1/2-gallon tank for added versatility.

Video Transcript for Review of Pacbrake Vehicle Suspension - Alpha HD Towing/Load Leveling Kit - PB65FV

Hello, everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the Pacbrake Alpha HD air bag suspension kit for your rear axle. It has a 5,000-pound load leveling capacity. Now this part is a custom-fit part. It does fit certain models of 2003 to 2020 Dodge Ram trucks. What I would recommend is you go to our website, use the fit guide, put in your year and model vehicle, and it'll show which one if this will work for your application.

Now these air bags here will 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 brackets, the Grade 5 plated hardware, comes with the air lines with the inflation valves, and up here we've installed the push-to-connect fittings for your air lines to your springs. Does come with some installation instructions that'll describe how this all goes together. Basically, when the trailer is loaded and your bed is full, your truck's gonna need more than just the stock rear springs to stay level and in control.

That's where these Alpha HD air springs will come into play. They're 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 fifth wheel, hauling materials, or towing equipment, this upgrade's gonna keep you from sagging, squatting, and struggling for control. And also, one load isn't like the next load. That's why this Pacbrake will give you freedom to adjust your air pressure from 5 all the way up to 100 PSI.

So basically, if you need full support for a loaded trailer, pump it up. If you're unloaded and 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 you can basically start with just the simple manual inflation and then you can expand your system later with onboard air or wireless controls. And this Alpha HD is designed to scale with your setup, so it makes future upgrades easy without redoing the foundation.

Now I did wanna zoom in. 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 do use 20 internal wires on the spring to handle extreme loads without giving in. And they use corrosion resistant parts. The roll plates for protection of the springs and the powder-coated brackets will ensure that the system holds up through road salt, rain, mud, and even over time. Now the precision laser-cut brackets, they are designed to bolt cleanly to your truck's factory mounting points without welding or drilling to 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 air bag suspension kit for your rear axle.
