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.

Hello, everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the Pacbrake Alpha HD Pro airbag suspension kit with the internal jounce bumpers for your rear axle. Has a 5,000 pound load leveling capacity. Now this is a custom fit part. It is designed to fit the 1988 to 2000 Chevrolet Silverado and GMC Sierra 1500, 2500, and 3500, both two wheel drive and four wheel drive trucks. And on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year model vehicle, and I'll show you, 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 for your rear axle. It includes the upper and lower roll plates, the precision laser cut powder coated steel brackets, the grade five plated hardware, and the airlines push to connect fittings right here, inflation valves and installation instructions. Now, basically, when your trailer's loaded and the bed is full, your truck needs 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. These will 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 is gonna keep you from sagging, squatting, and struggling for control. Also, bottoming out doesn't just feel rough. It can also wreck your airbags.
That's why this system here includes the jounce bumpers, which are on the inside of each Air Spring. So even with no air pressure, your suspension has a built-in safety net. Basically, you can safely run at 0 PSI when you're unloaded, which means no harsh rebound, just a nice smooth factory style ride. Also, one load isn't like the next. That's why this pack brake will give you freedom to adjust the air pressure from 5 to 100 PSI.
Basically, you need full support for a loaded trailer. Just pump it up. If you're unloaded, heading home, drop the pressure for a lot smoother ride. Again, the simple manual inflation right out of the box give you better ride quality and confidence no matter how much you're hauling. Now, I wanted to zoom in a little bit just to show you this isn't light duty gear. The Alpha HD Pro Springs are built with one inch thick end caps on both ends of the springs, and they use 20 internal wires on the spring to handle extreme loads without giving in. All the corrosion resistant parts. The roll plates for protection and in the powder coated brackets will ensure that this system holds up through road salt, rain, mud, and time. Now, these are designed to bolt to your factory mounting points on your Chevy or GMC truck. This Air Spring kit installs with no frame drilling required. All you do is start with simple manual inflation and you can then expand your system later with onboard air wireless controls if you need to. This Alpha HD Pro is designed to scale with your setup, so making future upgrades easy without having to redo the foundation. Also, one thing I we wanna mention is the Air Springs will not increase your vehicle's weight carrying capacity. So you do wanna make sure not to exceed the manufacturer's recommended weight limit. But that's gonna do it for a look at the Pacbrake Alpha HD Pro airbag suspension kit with the internal jounce bumpers for your rear axle.

Nice! Glad we could help, Bob! I've seen a few people that did those Titan conversions and they can turn out pretty wicked! What's the first trip you have planned?
