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 everyone, Steven here with etrailer.com. Today we're looking at our Pacbrake Alpha SD air bag suspension kit. It's what we call a sleeve style, and it's a rear axle application ready for 1,800 pounds. Now folks, these are custom fit, so make sure you're checking our fit guide here at etrailer.com. Be sure you're getting the right parts the first time for your specific setup. And you can call, chat us.
We'll be more than happy to assist you with that part or any other parts as well. Now, as you can see today, I just have these loosely fitted together on the table to kinda show you the size, shape, and everything. You will get everything pictured in the image here on the screen, as far as all the brackets, airlines, airline cutting tool, all the fittings, all the nuts, bolts, the clamps. Everything you need will come with this kit. So again, I just have this part on the table today just to kinda give you a visual about the size of these and everything.
1,800 pounds capacity, durable. The hardware and everything has been laser cut as far as the brackets. Everything's a nice powder coat finish. The bags are reinforce, or non-reinforced rubber that's gonna resist corrosion, and cold weather cracking, and those kinda things as well. So, a very nice kit.
(air wheezing) And as you can hear, air can go in and out whenever I'm pushing on it. Now, once you have this installed correctly, it is a manual inflation at the rear bumper of the vehicle. And again, everything here is just loosely fitting today for our viewing. So again, very nice kit from Pacbrake. It's gonna reduce rear end sag, absorb road shock, and keep your steering crisp and clean under load so you're not gonna be bouncing around like you probably are currently if you don't have something like this on your setup.
Well folks, that's gonna wrap it up for our look together. I'm Steven. Thanks for watching.
The air bags seem to work well. The installation was tricky and I wouldn’t recommend it for the amateur.
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!
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.
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.
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!
