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 this 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 2007 to 2018 Chevy Silverado and GMC Sierra 1500 trucks.
Both two-wheel drive and four-wheel drive. It does also fit the 2019 Chevy Silverado Light Duty 1500 and the GMC Sierra Limited 1500. Also both two-wheel and four-wheel drive vehicles. Now, a couple notes. These will work for the short and medium length truck beds, and they will not fit a vehicle that is equipped with the MagneRide.
But 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 it'll show you if this will work for your application. Now, these airbags right here are gonna help you stay level, drive steady, and stay in control when you're hauling heavy loads. This kit will include everything I have laid out here on the table. Includes the air springs right here for the rear axle, both the upper and lower roll plates, the precision laser cut powder coated steel mounting brackets. Up front here, we have the grade 5 plated hardware.
Over here, the air lines with the inflation valves. Now, the push-to-connect fittings we've installed already on the top here. That's what your air lines will connect to. And it comes with a nice set of installation instructions that'll show you 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 controlled.
These Alpha HD Pro Air Springs 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 keeps you from sagging, squatting, and struggling for control. And also with this kit, bottoming out doesn't just feel rough, it can wreck your airbags. So, with this HD Pro System Kit, it includes that jounce bumper that's on the inside of each spring. So, even if there's no air pressure in the air spring, your suspension has a built-in safety net. You can safely run at zero PSI when you're unloading, which means no harsh rebound. Just a nice smooth factory style ride. And as you're familiar, one load isn't like the next. That's why this Pacbrake gives you the freedom to adjust your air pressure from 5 to 100 PSI. So basically, if you need full support for a loaded trailer, you just pump it up. And then if you're unloaded, heading home, drop the pressure for a lot smoother ride. And also 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. You just start with the simple manual inflation, or you can eventually expand your system later with onboard air wireless controls. The Alpha HD Pro System is designed to scale with your setup. So, making future upgrade's real easy without having to redo the whole foundation. And also, this isn't light duty gear. Let me just zoom in so we can show you. These springs right here, these are Alpha HD Pro Springs and they're built with one-inch thick end caps on each spring. And then, they use 20 internal wires in the spring to handle extreme loads without giving in. And these are corrosion-resistant parts. The roll plates we mentioned, upper and lower are for protection of the spring. And the powder coated brackets will ensure that the system holds up through road salt, rain, mud, and over time. Now, the precision cut laser brackets here, the mounting brackets, they are designed to bolt cleanly to your truck's existing mounting points without welding or drilling your frame. Now, these air springs will not increase your vehicles 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?
