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.
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.
Bottoming out doesn't just feel rough, it can wreck your air bags. That's why this system includes jounce bumpers inside each bag, so even with no air pressure, your suspension has a built-in safety net. You can safely run at 0 psi when unloaded, which means no harsh rebound just that smooth, factory-style ride. If you're heading to work with an empty bed or cruising home after dropping the trailer, your truck stays comfortable, controlled, and ready to haul again with just a quick bump in pressure.
Every haul is different. That's why Alpha HD Pro air springs give you full control over ride height and firmness with adjustable air pressure from 5 to 100 psi. Hauling a fifth wheel or a full bed of gravel? Crank up the pressure. Unloaded and heading home? Drop it back down for a softer ride. With manual inflation valves included, tuning your suspension for the day's work is straightforward.
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 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 (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.

Hello, everybody. This is Jeff at etrailer.com. Today I'm gonna take a look at the Pacbrake Alpha HD Pro airbag suspension kit with the internal jounce bumpers for your rear axle. This has a 5,000 pound load-leveling capacity. Now this is a custom-fit part. It is designed to fit the 2001 to 2010 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD trucks, and it'll work on either two-wheel drive or four-wheel drive models.
Now this is for all trucks including those with fifth-wheel hitches. One note is this will not fit cabin chassis vehicles. And on a custom-fit part like this, I like to 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 hauling heavy loads. It will include everything laid out here on the table.
It includes the air springs for the rear axle, the upper and lower roll plates, all the precision laser-cut, powder-coated steel mounting brackets. Also, the grade 5 plated hardware. Comes with airlines with the inflation valves. And right up here you can see the push-to-connect fittings for your airlines to connect to. Also comes with installation instructions that'll show how this all goes together.
Now, basically, when your trailer's loaded and the 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 Pro 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, basically, whether you're pulling a fifth wheel, hauling materials, or towing equipment, this upgrade, it's gonna keep you from sagging, squatting, and struggling for control. Also, bottoming out doesn't just feel rough, it could wreck your air springs.
That's why this system here includes the jounce bumpers that are inside each spring. And that's so, even what happens with that, is even with no air pressure in the spring, your suspension has a built-in safety net. So basically you could safely run at 0 PSI when you're unloaded, which means no harsh rebound, just a smooth factory-style ride. Also, one load isn't like the next. This Pacbrake system gives you the freedom to adjust the air pressure from 5 PSI up to 100 PSI. So, basically, if you need full support for a loaded trailer, just pump it up. If you're unloaded and heading home, you can drop the pressure for a smoother ride. So 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 what's nice is you can start simple with the manual inflation, and then, if you want, you can expand your system later with an onboard air or wireless controls. This Alpha HD Pro system is designed to scale with your setup, so making future upgrades easy without redoing your foundation. Now I did want to zoom in a little bit closer 'cause this isn't light-duty gear. These Alpha HD Pro springs are built with one-inch thick end caps on each spring, and they offer 20 internal wires to handle extreme loads without giving in. Parts are all corrosion-resistant parts. Roll plates right here give you protection for your airbags, and the powder-coated brackets will ensure the system will hold up through road salt, rain, mud, and even over time. Now these are designed to bolt to your factory mounting points on your truck. This air spring kit installs with no drilling or welding to the frame. These air springs will not increase your vehicle's weight-carrying capacity, so you want to make sure not to exceed the manufacturer's recommended weight limit. But that's gonna do it for a look at this Pacbrake Alpha HD Pro airbag suspension kit with the internal jounce bumpers for your rear axle.
Easy to install and looks like it’s a high-quality product
