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.
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.
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.
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.
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.
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.

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha HD Pro Rear Axle Single Convoluted Airbag Suspension kit with internal jounce bumpers. Now this kit has been designed for your 2003 to 2013 Dodge Ram 2,500. Then your 2003 to 2018 Ram 3,500 two-wheel drive. Then your 2006 to 2008 Ram 1,500 and 2,500 Mega Cab two-wheel drive.
And then finally your 2006 to 2018 Ram 3,500 Mega Cab two-wheel drive. I do wanna point out that these are not going to fit with the 3349 and the 3319 Super Glide Fifth Wheel Rail kits on rear wheel drive vehicles. Now on custom fit parts such as this kit, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Simply input the year, make, and model of your vehicle and our fit guide will confirm if this kit will work for you or if we have something comparable that will work for you. So as you know, when the load gets heavy, your truck is going going to need more than just your rear springs hanging on for dear life.
So these airbags are going to add up to 5,000 pounds of rear axle support, keeping your truck level and steady even when the trailer is loaded, the bed is packed, and the miles are long. So no more rear end sagging throwing off your braking and steering or headlights pointing up into the sky. Now bottoming out doesn't just feel rough, it can wreck your airbags. That's why this system includes internal jounce bumpers inside each of these bags. So even with no air pressure, your suspension is going to have a built in safety net.
You can safely run at zero PSI when unloaded, which means no harsh rebound, just that smooth factory style ride. Now every haul is going to be different, as you know. That's why these air springs give you full control over the ride height and firmness with adjustable air pressure from five to 100 PSI. So hauling a fifth wheel or a full bed of gravel is not gonna be any problem because you can just crank up the pressure and then when you're unloaded and heading home, you can drop the pressure back down for a softer ride. With the included manual inflation valves and airlines tuning your suspension for the day's work is gonna be very easy and very straightforward.
So extreme hauling is going to demand extreme durability. These springs are built with one-inch thick corrosion resistant end caps that you really can't see because I do have these loosely assembled and in between these plates here, so the one-inch thick end caps are really going to keep these the integrity intact along with the reinforced 20 internal support wires giving you maximum strength under that load. And then these roll plates that I mentioned, these are heavy duty roll plates that are gonna actually protect the bags from chafing and extend the lifespan. And then these powder coated custom fit steel brackets are going to fight back against rust, road salt, and rough season. So if it's bitter cold, it's the scorching heat or the mud slick job site, this system is made to outlast whatever the road is going to dish out mile after mile and load after load. And I have dealt with several other brands of airbag systems and this in my opinion, is probably the most premium that I've come across. The bags are made of very premium material, they feel robust. And then with our custom fit brackets here, the powder coating, it's top notch as well. So, again, probably the most premium top tier airbag system that I've come across here from Pacbrake. So these precision laser cut brackets are designed to bolt cleanly to your Ram's existing mounting points without welding or drilling to your frame. So you'll just use the included hardware and this kit is going to be designed to work with your setup right now and wherever your upgrades may take you later on. So you're gonna be able to inflate manually with standard air valves right out of the box. No extra parts needed. But if you already have an onboard compressor, these are gonna connect easily to most existing setups. Or if you're planning for an in cab wireless controller down the road, that's not gonna be an issue because you're laying the foundation with this kit. It's gonna be very easy to expand your control options when you're ready. So again, this is going to give you a load support up to 5,000 pounds of additional leveling support, but I do wanna make you aware of the fact that these do not actually increase your weight carrying capacity of your truck. So you wanna make sure that you're not exceeding your manufacturer's recommended weight limit. Instructions are included to guide you through the installation process. And if you do decide to pick these up, we would love to hear back from you regarding how the installation went and how these are working out for you. So you can share your experience with us by dropping a comment or leaving a review on this product page. And if you have any other additional questions, don't hesitate to give us a call. Well, that's gonna wrap up our look today. I do hope that our time together was helpful for you. Again, my name is Andy. Thank you for joining me.
Easy to install and looks like it’s a high-quality product
haven't received or used it yet but pretty darn excited
The brackets are not built heavy enough
Easy install. Will pull trailer 3000 miles on vacation and see how it performs to Montana on highways and Forest Service roads.
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 !
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
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,
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.
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.
