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.


Highlights

  • Custom Fit for Your Vehicle: Precision brackets bolt to factory attachment points.
  • 5,000-lb Load Support: Reduces rear-end sag, sway, and bounce for better handling under load.
  • Ride Smooth When Unloaded: Internal jounce bumpers protect ride quality with no air in the bags.
  • Adjustable Air Pressure: Set support between 0 psi and 100 psi depending on your load.
  • Complete Kit, Minimal Drilling: Includes laser-cut brackets, push-to-connect fittings, and all hardware.
  • Ready Now, Upgrade Later: Use manual inflation or connect to onboard air when you're ready.

Features to know about

Control and Cushion When It Counts

Heavy trailers, full beds, gear piled high, it all changes how your truck handles. Without the right support, you feel it immediately: sagging in the rear, poor handling, and a ride that gets unpredictable fast. This air bag system puts you back in control with up to 5,000 lbs of load-leveling support it helps reduce squat, improve steering response, and keep your truck stable when the weight stacks up.

Comfort When Unloaded, Control When Loaded

Every haul is different, and your suspension should keep up. Alpha HD Pro air springs give you full control over ride height and firmness with adjustable air pressure from 5 to 100 psi. Driving unloaded? The built-in jounce bumpers let you safely run at 0 psi for a smooth, factory-style ride with no harsh rebound. Hooked up to a fifth wheel or hauling a bed full of gravel? Add air to level the truck and keep handling tight. With manual inflation valves included, tuning your suspension for the day's load 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 Pro bags are reinforced all the way through with heavy-duty end caps, 20 internal support wires, integrated jounce bumpers, and powder-coated steel brackets. Toss in 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 DIY-er. 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 Pro 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 - Towing/Load Leveling - PB43VV

Hi, everyone, Steve here with etrailer.com. Let's take a look at our Pacbrake Alpha HD Pro Airbag Suspension Kit with Internal Jounce Jumpers for the rear axle, rated of 5,000 pounds. Now, folks, these are gonna fit a lot of different Dodge Sprinters, Freightliner Sprinters, Mercedes-Benz Sprinters, the 2500 Series, different years, makes, models. Make sure you're checking our Fit Guide here at etrailer.com. Be sure you get the right parts the first time. Now, these are gonna give you precision brackets.

These are gonna make it easy to bolt onto your factory attachment points. It's a complete kit. There's minimal to no drilling, so a little bit of drilling. It includes laser-cut brackets, as I mentioned, and push-to-connect fittings on the hardware and on the top here where the airlines going into it, and I'll throw up an image image real quick of all the hardware and all the parts you're getting. When it comes outta the box, it's gonna look something like that.

I've got it just kind of mocked up here today as far as what they could potentially look like when they're installed. Keep in mind I may not have 'em on the correct side depending on your viewing angle and all that kind of stuff, so just bear with me on that. You get all the brackets, again, all the hardware, cable ties, the airline, and there is again, inside of here, an internal jounce bumper. And what that's gonna do is you could technically be at zero PSI when you're unloaded, and that would still give you some stability and some weight-carrying capacity, but not too much. Other than that, you can go from five to 100 PSI on these double-convoluted bags, and they're gonna support up to 5,000 pounds of additional leveling support.

Now, they're gonna give you a smooth ride when you're unloaded as well because of that internal jounce. But that being said, you're gonna have to have some weight in the bed of your truck for these to work to their best. And what I mean by that is if you have an in-bed camper, maybe a super-heavy toolbox, maybe you're a construction, heavy equipment operator and you've got a lot of gear in the bed of your truck all the time, these will probably gonna be a great option. If you're just the person that's going camping once or twice a month, maybe, maybe a few times a year, and you really don't have a bunch of weight in your truck bed at all times, you might not wanna go with the internal jounce option here. You might wanna go with the one we sold separately that doesn't have that included, just to give you a better ride when you are empty, because remember, that's gonna support some, even whenever there's no weight in the bed of your truck, so it's not gonna have that same amount of flex in it that the ones without it would, so just keep that in mind.

Well, folks, that is gonna wrap it up for our quick look together at these Pacbrake Alpha HD Pro Airbag Suspension with the Internal Jounce Stoppers. Again, my name is Steven. Please, if you have any questions, comments or concerns, reach out to us. We'd be more than happy to assist you. Have a good one.

by:

The brackets are not built heavy enough



by:

Easy install. Will pull trailer 3000 miles on vacation and see how it performs to Montana on highways and Forest Service roads.



by:

good product , good strong solid metal parts and heavy bags. The instructions were not so hot but was easy to figure out and quick delivery !



by:

Where to start I have 1500 pounds of tools in my 150 Chevy had them installed and it totally changed the ride and handling of the truck haven’t pulled anything yet but I’m amazed on how different the truck is already I Baught the ones with the bump stops in them the HD ones



by:

I'm Vincent J,
My experience with loading
my truck and seeing the difference with these air bags from PacBrake, it does look way better and the truck feels a bit more stable running atspeed limit (65mph) after that it does feels jumpy if you go over potholes, but overall I'm happy with the product, thanks Etrailer,



by:

2020 Ram 1500.
Installation is fidgety
with lining everything together for the upper bracket with u-bolt(reason for 4 stars), but still preferred over cutting the bump stop mounts off. Replaced the Timbrens with this and it is night and day difference in ride quality both unloaded and towing.
Would purchase again.



by:

Product is well constructed and installation is straightforward. But you cannot build the kit and slip it in, you have to leave the top bracket off and install it after setting the lower bracket and air bag in place. I will note, I was working off jack stands and a floor jack, not on a lift.
