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 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.

Video Transcript for Review of Pacbrake Vehicle Suspension - Alpha HD Towing/Load Leveling Kit - PB82FV

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 low leveling capacity. Now this is a universal kit that'll fit many, but not all of the early model Dodge Forward and GM trucks. And on a fit like this, I do 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.

It will include everything I have laid out here on the table. It includes the air springs themselves right here for your rear axle, the upper and lower roll plates. The precision laser cut powder coated steel brackets, comes with some grade five plated hardware. The airlines with the inflation valves push to connect fittings, which we've put on install 'em already right up here for your airlines to connect to and even comes with some nice installation instructions that'll describe how this all goes together. Basically, when your trailer's loaded and the bed's 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 come into play 'cause these 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's gonna keep you from sagging, squatting, and struggling for control. And also, one load isn't like the next. That's why this Pacbrake gives you freedom to adjust the air pressure from 5 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 nice smoother ride. And again, with simple manual inflation right out of the box, you're gonna get better ride quality and confidence no matter how much you're hauling. Basically, you just start with the simple manual inflation or expand your system later using onboard air wireless controls. This Alpha HD kit is designed to scale with your setup, so it makes future upgrades easy without redoing the foundation. Now, I did wanna zoom in closer to show you show you this isn't light duty gear.

These Alpha HD springs right here are built with one inch thick end caps on each spring. And the spring itself uses 20 internal wires to handle extreme loads without giving in, uses corrosion resistant parts. The roll plates, we mentioned the upper and lower roll plates right here. These are for protection of the springs and the powder coated brackets ensure that this system will hold up through road salt, rain, mud, and even over time. Now they are a drill to fit installation. It does include the brackets in the hardware for a clean install on older frames, but these air springs will not increase your vehicle's weight carrying capacity. You do wanna make sure to remember that you do not want to exceed your 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.

Thank you Joshua for your assistance.

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



by:

It was very easy install . The ride has improved a lot while towing my 41 ft. toy hauler , Thanks !!



by:

Direct bolt on, plug and play



by:

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.



by:

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!



by:

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.



by:

Very well built brackets, installation was as explained in the instruction. Happy Camper!



by:

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!



by:

Easy install and done exactly what I needed it to do

  • Pacbrake Air Bag and Compressor Kit for 1995 Ford F-350
    Hey Kirk, yes Pacbrake does make an air bag kit that fits your 1995 Ford F-350 with the part # PB82FV. This does not come with a compressor though so you'd have to add that separately like with the # PB65VV. Have you used a Pacbrake air bag kit before?

  • Air Bag Kit For 2002 Dodge Ram 3500 With In-Bed Hitch
    Hi Chris! There are not a lot of options that are a fit for an 02 Dodge Ram 3500 with an in-bed gooseneck or 5th wheel hitch (which is what I assume you mean by pintle hitch, but if I am wrong, please let me know). The only option that is will be the Pacbrake Alpha HD Air Bag Suspension Kit - 5,000 lbs # PB82FV. This is a universal kit, so drilling is required and there is no compressor included. For that you will want the Air Lift Air Shock Controller Compressor System # AL25804. It's...
