2,000-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 an older Ford, Dodge, Chevy, or GMC truck, shouldn't lead to sloppy steering, poorly aimed headlights, 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 2,000 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. When your cargo changes, your truck adaptsno tools, no shop visit, just smart, simple control you can handle yourself.
Even moderate 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 constant adjusting, no clunky ride, just consistent comfort and control.
Serious load support takes serious mounting strength. This Alpha SD kit uses laser-cut, powder-coated steel brackets that may require some frame drilling for a secure, lasting fit. All lines, fittings, valves, and hardware are included, along with detailed instructions that make the job straightforward for experienced DIYers and upfitters. Rain, mud, or freezing cold, this setup is built to handle it all. With rugged air springs, corrosion-resistant parts, and a lifetime warranty behind it, you're not just leveling your load - you're investing in long-term durability and peace of mind. Planning for onboard air later? These bags are ready to grow with your setup - just add a compressor when you're ready.

Hello everybody. This is Jeff at etrailer.com. Today I'm gonna take a look at the Pacbrake Alpha SD Airbag Suspension Kit for your rear axle. This has a 2000 pound load leveling capacity. Now, this kit is a custom fit kit. It is designed to fit select 1966 to 2008 Chevrolet, GMC, Dodge and Ford trucks with these precision cut brackets.
Now, on a custom fit part like this, I would like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now basically, loading up your older truck shouldn't lead to sloppy steering, sketchy braking, or poorly aimed headlights. But the factory suspension can only do so much before heavy loads start dragging everything down. So this Alpha SD Air Spring Kit adds up to about 2000 pounds of load support to your rear axle, keeping your stance level and your handling sharp. So it's gonna mean better traction, safer braking, and your headlights are gonna stay where they belong, which is especially important when you're hauling at night, you're in rough weather.
Now, if you're moving work gear, towing a small trailer or packing for a weekend trip, you're gonna feel the difference in every mile you drive. This kit will include everything I have laid out here on the table and includes the Alpha SD Sleeve Style Air Springs for the rear axle. Up here we've connected the push to connect airline fittings, the precision laser cut powder coated steel mounting brackets, grade five plated hardware. This one even includes a nylon mounting bracket alignment tool for installation, air lines with the manual inflation valves and a nice set of installation instructions are all included. Now, no two hauls are exactly the same, and your suspension shouldn't be stuck in a one size fits all setup.
So with this simple manual inflation, you could dial in the air pressure anywhere from 10 PSI for empty cruising, all the way up to 100 PSI when your bed is loaded or the trailer is hooked to it. This is a nice, fast, flexible way to get your truck back to level without guessing or settling for a rough ride. And basically when your cargo changes, your truck's gonna adapt. So there's no tools, no shop visit, just smart, simple control that you could handle yourself. Now, I did want to zoom in closer onto these air springs here.
They are a smart sleeve style design air spring. So you can safely lower the pressure down to 10 PSI, and when it's unloaded without losing control or beating yourself up on rough pavement. So this is gonna mean a nice, smooth, predictable ride, whether your bed is stacked with cargo or empty and ready for weekend cruising. There's no constant adjusting, no clunky ride, just consistent comfort and control. Now, this system is gonna bolt up cleanly with the laser cut powder coated steel brackets that amount to factory points. As we mentioned, they include this nylon mounting bracket alignment tool to help you install those brackets. The mounting hardware itself will resist corrosion, and everything you need is in the box, lines, fittings, valves, and the detailed instructions. Now, if you're also thinking about going onboard air down the road, these bags are built to grow with your setup. All you have to do is just add a compressor when you're ready. One note I do wanna mention. These airbags 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 SD Airbag Suspension Kit for your rear axle.
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!
This Pacbrake kit is excellent, reason for the 4 star is because the instructions are not exactly accurate but one can figure it out and the self tappers are not the 8mm as described but 10mm, this is an issue when using a tap to thread the holes because the the bolts will not self thread into the pre-drilled holes. The ride with 14 psi has improved the handling and when i throw a few hundred pounds in the box the truck doesn't squat. exactly how i want it.
Purchased for 2024 GMC Canyon Elevation trim 4x4. Needed to take out the 2-in drop from my travel trailer hitch weight of 400 lb.
Ordered on E-Trailer which sent the order to their supplier who took 4 days from the time they received it to actually ship it. This meant it burned past the originally stated delivery date by 3 days.
Once it arrived all the parts were there. Everything was labeled, packaged up and included instruction sheets.
Install went fine with two issues:
1. The included self-tapping bolts for mounting the upper portion to the frame would not self-tap into the existing holes. I had to use a tap to put the threads into the hole.
2. I tested the air valve with the shock out of the vehicle (probably shouldn't have) which expanded it to full height, which meant when I compressed it for installation it was crumpled and folded onto itself and not the way it was supposed to be sleaved. This issue was solved after I increased the air to 90 PSI and put a trailer load of 400 pounds on the hitch. While releasing air the sleeve compressed back into proper shape.
I love that they included the cutter for the air hoses which made it easy. No leaks.
Ride while towing was the same as before (great) without the rear drop and nose high lights. Driving with no load and the minimum 10 psi didn't give any noticeable bounce or increased stiffness.
