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 grow with your upgrades tomorrow. You can inflate manually through the included 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.
Want to step up to an all-in-one kit with air bags, compressor, and wireless controller in one package? We've got you covered with Pacbrake's On Demand Kit (PB39YV).
Looking for a complete system with onboard air storage too? Upgrade to one of the "Ultimate" Kits (PB95YV) or (PB45YV) with air bags, compressor, wireless controller, and 1/2-gallon or 2-1/2-gallon air tank for added versatility.

Hi, everyone, Steve here with etrailer.com. Today, we're looking together at our Pacbrake Alpha HD Pro Air Bag Suspension Kit with internal jounce bumpers. Folks, this are for the rear axle, and they're rated at 5,000 pounds capacity. Now, these are custom fit, so make sure you're getting in the right parts for your specific vehicle. In this case, it looks like they're fitting an '05 to '23 Toyota Tacoma. Now, folks, these are gonna be loosely fit together on my table today, so this is kinda what they look like when they're installed.
I wanna start off by showing you what that jounce looks like inside that internal jounce stop, or bump stop some people call it. That's that orange thing there in the cutout picture there. That's gonna always be in there, so even if you, God forbid, had a loss of air pressure, you would still have something in there to keep you, you know, some stability. Now, everything that's in this other picture I'm gonna throw up, that's what you're gonna get included in the box. All the hardware, the air line, the push-to-connect fittings, all the laser-cut precision brackets, all the air bags, hardware, everything you see there is gonna be included.
So again, I just have these kinda loosely fitted together on the table today for your viewing pleasure. There's the bottom, back. So again, folks, why air bags Well, if you're squatting in the back of your vehicle and your lights are pointed up towards the sky, these will help get your back level, keep the traction where it needs to be on the front and the rear simultaneously, so giving you that load support. It's gonna increase, again, stability, ride quality, reduce that rear-end sag, sway, and bounce, giving you a much smoother ride. These can hold between 5 to 100 psi, depending on your load.
And as I mentioned, they have an internal jounce inside of there. So these are ready to go out of the box as far as once you put them together and install them. For manual inflation, you can connect or purchase separately and on-board air system if you so choose to then do it all from inside the cab. Now, I wanna speak a little bit about that internal jounce. So a lot of people will call in like, "Hey, do I need this Do I not need this" What the installers have told us over the years and the tech support with the manufacturer as well is that that internal jounce is gonna be great if you're the kinda person that has a super heavy load in the bed at all times.
Whether it's an in-bed camper, you're a contractor, you got job boxes, heavy tools, whatever that's always back there, these would be a great option for you. If you're only towing heavy loads every once in a while, you actually might not like these in there all the time with that internal jounce. You might wanna pick up the ones that don't have the internal jounce in there that fit this same year, make, and model just to give you a smoother ride all the time. So again, it's great when you have those extra heavy-duty loads in there all the time, but some people have told us over the years that, "Hey, with these internal jounces, I feel every bump now in the road when I'm empty. What can I do about that" So keep that in mind whenever you're picking out the right one for your specific needs. If you're not sure, call us, chat, email, we'll be more than happy to assist you with picking out the right suspension kit for your specific setup. Folks, I'm Steven, thanks so much for watching. Have a good day.

Easy to install and looks like it’s a high-quality product
haven't received or used it yet but pretty darn excited
The brackets are not built heavy enough
Easy install. Will pull trailer 3000 miles on vacation and see how it performs to Montana on highways and Forest Service roads.
good product , good strong solid metal parts and heavy bags. The instructions were not so hot but was easy to figure out and quick delivery !
Great quality!
So far so good two trips with camper and worked great !
Where to start I have 1500 pounds of tools in my 150 Chevy had them installed and it totally changed the ride and handling of the truck haven’t pulled anything yet but I’m amazed on how different the truck is already I Baught the ones with the bump stops in them the HD ones
Thanks Ashley. I did not open yet wait next week Friday I work on van
I'm Vincent J,
My experience with loading my truck and seeing the difference with these air bags from PacBrake, it does look way better and the truck feels a bit more stable running atspeed limit (65mph) after that it does feels jumpy if you go over potholes, but overall I'm happy with the product, thanks Etrailer,
2020 Ram 1500.
Installation is fidgety with lining everything together for the upper bracket with u-bolt(reason for 4 stars), but still preferred over cutting the bump stop mounts off. Replaced the Timbrens with this and it is night and day difference in ride quality both unloaded and towing.
Would purchase again.
Lifts the truck back to normal with a heavy load. Feels so much safer on twist and turns and even just pulling into the store.
Product is well constructed and installation is straightforward. But you cannot build the kit and slip it in, you have to leave the top bracket off and install it after setting the lower bracket and air bag in place. I will note, I was working off jack stands and a floor jack, not on a lift.
Product was exactly as described delivered fast and easy to install. Only two bolts didn’t fit. No problem had some spare ones that worked. Would definitely recommend this product and company
My kit had hardware that was too short and some hardware that was too long. Making the install difficult, having to use my old hardware to complete. The kid I ordered was supposed to fit my vehicle, not so much. All of my boxes had been re-taped, as if it was returned from a previous customer.
When I'm occasionally towing long distances it helps my Ram 1500 a lot. However, there's no psi happy spot for a smooth factory ride after the towing ceases and daily commutes return.
Order and delivery was easy and quick. Installation instructions were clear and was an easy install. Great product.
This product is everything they said it was. It was very easy to install my Ford transit T250 handles great now in my trailer hitch. It’s not dragging the ground. Thank you for a great product.
First off this is my first experience with air bags. When I was a kid it was air shocks. First, off tip of the hat goes to etrailer for fast delivery. Many times I read reviews where people complain about directions. These people I would guess have very little mechanical skills. The included instructions with these is very comprehensive and thorough. The would make this easy for the average guy. Second, soon as you start to unpack the parts you can tell this is heavy duty well made product. Everything fit perfectly. I gained 3 inch’s at 50 lbs. my build is a b class transit 250 van. 148EL. When you start building these things the weight adds up quick. Was starting to regret not getting a 350 but this saved the day. No miles on it yet but certainly clearance issue is solved,
I got it to work but the J Hooks that came with the kit were extremely short and I didn't want to wait for a new part but I made it work
