When the load gets heavy, your truck shouldn't feel like it's fighting you. These air bags help you stay level, drive steady, and stay 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 Silverado or Sierra level, steady, and confident 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, your cargo, and your peace of mind even when you're towing a travel trailer or moving a serious payload.
Every load is different. That's why Alpha HD air bags provide adjustable air pressure control between 5 and 100 psi. Need full strength for a heavy trailer? Pump it up. Dropping off the trailer and heading home light? Drop the pressure for a smoother ride. Simple manual inflation lets you adjust your suspension without the guesswork, so your truck feels balanced and comfortable whether you're packed to the gills or just running light errands.
Heavy hauling demands extreme durability. Alpha HD springs are built with one-inch thick, corrosion-resistant end caps and reinforced with 20 internal support wires for maximum strength under load. Heavy-duty roll plates protect the bags from chafing and extend lifespan. Powder-coated steel brackets fight back against rust, road salt, and rough seasons. If it's bitter cold, scorching heat, or mud-slicked job sites, this system is made to outlast whatever the road dishes out, mile after mile, load after load.
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 without welding or drilling your frame. 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. With high-quality fittings, pre-bent brackets, and mounting hardware included, you'll be back on the road with a stronger, steadier truck 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.

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha HD rear axle double convoluted airbag suspension kit. Now this kit has been designed for your 2019 and newer Chevrolet Silverado and GMC Sierra 1500 with the two and four-wheel drives. And this kit is going to work with all truck bed lengths. However, this is not going to fit models equipped with the adaptive ride control. If you have the AT4 or Trail Boss four-wheel drive models, you should use the kit that you see there on your screen instead, identified by the model number that you see there, which comes with the required two-inch spacer.
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 will work for you or if we have something comparable that will work for you. So when the load gets heavy, your truck is going to need more than just those factory rear springs hanging on for dear life. These airbags are gonna give you up to 5,000 pounds of rear axle support, keeping your truck level and steady, even when the trailer is loaded and the bed is packed and the miles are long. So you're not gonna have to worry about any more rear end sagging, throwing off your braking and steering or your headlights pointing up to the sky.
Every haul is different, of course. That's why these air springs give you full control over your ride height and firmness, with adjustable air pressure from five to 100 PSI. Hauling a fifth wheel or a full bed of gravel, then you can just crank up the pressure in the bags. And then when you're unloaded and you're heading home, you can just drop that pressure back down, giving you a softer ride. With the manual inflation valves included, tuning your suspension for the day's work is gonna be very easy, very straightforward.
Now if extreme hauling does demand extreme durability, these springs are built with one inch thick corrosion-resistant end caps, which you can't see because I do have them kind of loosely assembled, and I've got the roll plates here on the top and the bottom. But these also are reinforced with 20 internal support wires for maximum strength under that heavy load. And then these roll plates are heavy duty. They are designed to protect the bags from chafing and help extend their lifespan. And then these custom fit powder coated steel brackets are going to resist rust and corrosion, road salt, all those rough seasons, such as if it's a bitter cold or if it's scorching heat, or mud-slicked job sites.
This system is designed to outlast whatever the road is going to give you, mile after mile and load after load. Now I do wanna point out that with Pacbreak, the word that comes to mind is premium. I have dealt with in the past, with other manufacturers, airbag suspension kits. They all have their strengths, but I'm just immediately impressed by the quality of the materials that, especially the materials used to construct the bag, the powder coat finish on these brackets, everything with this kit just speaks of a premium quality to me. So if you're looking for a top-of-the-line air suspension kit, in my opinion, Pacbreak is going to be the way to go. These precision laser cut custom fit brackets are designed to bolt cleanly to your truck's existing mounting points without welding or drilling to your frame. You're just, of course, gonna use the included hardware. And so this kit is designed to work with your setup today. And wherever your upgrades are going to take you tomorrow, you're gonna be able to inflate them manually with the standard air valves right out of the box, no extra parts needed. And then if you already have an onboard compressor, these are gonna be able to connect easily to most existing setups. And then if you're planning for an in-cab wireless controller sometime down the road, that's not gonna be a problem, because with this kit, you're building that foundation so that you can expand in how you're going to control these down the road. So again, the load leveling support's gonna be up to 5,000 pounds, but just be aware of the fact that airbags do not actually increase the weight carrying capacity of your truck. So you do wanna make sure that you're not exceeding your manufacturer's recommended weight limit. If you do pick this kit up, we would love to hear back from you regarding your experience with the installation and the operation of this kit, and you can do that 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. We'd love to hear from you and help you out further. Well, that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
They need instructions to be more clear but fit very nicely i would recommend pacebrake
Going camping!!!
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.
