Arrives before Christmas To see if this custom-fit item will work for you please tell us what vehicle you'll use it with.
1,800-lb Capacity. Loading up your truck shouldn't make you dread the drive. These air bags keep you level and in control when packing for weekend adventures. It's a smart way to take the stress out of hauling and enjoy the drive again.
Loading up your vehicle shouldn't lead to sloppy steering, sketchy braking, or poorly aimed headlights. But factory suspension can only do so much before heavy loads start dragging everything down. Pacbrake's Alpha SD air springs add up to 1,800 lbs of load support to your rear axle, keeping your stance level and your handling sharp. That means better traction, safer braking, and headlights that stay aimed where they belong, especially important when hauling at night or in rough weather. If you're moving work gear, towing a small trailer, or packing for a weekend trip, you'll feel the difference in every mile you drive.
No two hauls are the same, and your suspension shouldn't be stuck in a one-size-fits-all setup. With simple manual inflation, you can dial in air pressure from 10 psi for empty cruising, to 100 psi when the bed is loaded or the trailer is hitched. It's a fast, flexible way to get your truck back to level without guessing or settling for a rough ride.
Heavy loads demand extra support, but when the weight comes off, you still want your truck to drive like a truck, not like a brick. Thanks to the smart sleeve-style air spring design, you can safely lower pressure down to 10 psi when unloaded without losing control or beating yourself up on rough pavement. That means a smooth, predictable ride whether your bed is stacked with cargo or empty and ready for weekend cruising.
No one buys an air bag kit to waste a weekend wrenching. This system bolts up cleanly with laser-cut, powder-coated steel brackets that mount to factory points. Mounting hardware resists corrosion, and everything you need - lines, fittings, valves, and detailed instructions - is in the box. Rain, mud, freezing cold, heavy hauls, this kit handles it all. With rugged air springs, corrosion-resistant parts, and a lifetime warranty to back it up, you're not just leveling your load, you're getting peace of mind that your truck's ready for anything. Thinking about onboard air down the road? With standard ports and fittings already in place, the foundation is built in, making it easy to expand when you're ready.

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha SD rear axle sleeve style air bag suspension kit. Now, this kit has been designed to fit your 2007 to 2018 Chevy Silverado or GMC Sierra 1500, the short bed or standard bed, two wheel or four wheel drive models. And 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 loading up your Silverado or Sierra should not lead to sloppy steering, poorly aimed headlights, sketchy braking, or other things that could go wrong with a heavier load. But factory suspension can only do so much before the heavier load starts dragging everything down. Now this kit is designed to add 1800 pounds of load support to your rear axle, keeping your stance level, your handling sharp, and that's going to mean better traction, safer braking, and headlights, that are gonna stay aimed where they belong. Now this is going to be especially important when hauling at night or in rough weather regarding your headlight aim. So if you are moving work gear or towing a smaller trailer or packing for a weekend trip, you're gonna feel the difference in every mile you drive with this kit.
So as you know, no two hauls are gonna be exactly the same, and your suspension shouldn't be stuck in a one-size-fits-all setup. With simple manual inflation valves, you're gonna be able to dial in the air pressure from 10 PSI for empty cruising up to 100 PSI when the bed is loaded or the trailer is hitched in a fast, flexible way to get your truck bed back to level without guessing or setting for a rough ride. This is gonna be a kit to really consider. When your cargo changes, your truck is going to adapt. You're not gonna have to worry about tools or a shop visit, just smart simple control that you can handle yourself.
Now, heavier loads do demand extra support, but when the weight comes off, you still want your truck to drive like a truck. So thanks to the smart sleeve style air spring design, you're gonna be able to safely lower pressure down to 10 PSI when unloaded without losing control or beating yourself up on rough pavement. So that's gonna mean for you a smooth, predictable ride, whether your bed is stacked with cargo or empty and ready for weekend cruising. No constant adjusting, no clunky ride, just consistent control and comfort. These precision laser cut brackets are designed to bolt cleanly to your truck's existing mounting points without welding or drilling.
Just gonna use the existing hardware. You can see I do kinda have this set up loosely assembled just to kinda give you an idea of what this is going to look like when this is all set up. And this kit is designed to work with your setup today, wherever your upgrades take you tomorrow. So you can inflate manually with standard air valves right out of the box, no extra parts needed, or if you already have an onboard compressor, these are gonna connect easily to most of those existing setups. And then if you're planning for an in-cab wireless controller down the road, you're setting the foundation with this kit. So it's gonna be easy to expand your control options when you're ready. So again, the load leveling support is gonna be up to 1800 pounds, but the air springs do not actually increase your truck's weight carrying capacity. So you do wanna make sure that you're not exceeding your manufacturer's recommended weight limit. If you do decide to pick this set up, we would love to hear back from you regarding the installation and what you think about the operation of this kit. So you can drop a comment or leave a review on this product page. If you have any additional questions, don't hesitate to give us a call. Well, that's gonna wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
The air bags seem to work well. The installation was tricky and I wouldn’t recommend it for the amateur.
Easy installation. Instructions are pretty simple. Be sure to follow torque specs. Add a little thread seal tape to your 90 swivel fitting to prevent leaks.The heat shield was not necessary for my year model(2024),since there was plenty of space between the air bags and the exhaust. Instead of drilling holes under license plate, I just used the screw hole for my license plate for schrader valves. Just drilled out the license plate holes out and little placed through. No more bouncing or suspension sag. Recommended!
Bolted right into place, GMC Canyon. No installation issues or hang up’s. Whole thing Might have taken about 3 hours. Pumped em’ up and have been driving for a week, no leaks no issues. I recommend!
