Features to know about

Built to Handle Serious Loads and Keep You in Control

When your truck or van is built to carry serious weight, factory suspension alone won't cut it. Alpha XD (Extreme Duty) air springs add up to 7,500 lbs of rear axle support to keep your vehicle level and steady under pressure. If you're hauling heavy gear or equipment, you stay in control with less squat, better stability, and more predictable braking.

Adjustable Support for Every Haul

Some days you're maxed out, others you're running light. With Pacbrake's 5 to 100 psi adjustable range, you get the right support for every trip. When carrying heavy weight, add air to level your suspension and maintain steady handling. Running without a load? Drop to the minimum pressure for a smoother, more compliant ride without stiffness or bounce. Manual valves let you adapt your suspension to whatever the day throws at you.

Made to Survive the Real World

Built for demanding commercial use, Alpha XD springs use one-inch thick, corrosion-resistant end caps and 20 internal support wires for extreme strength. Heavy-duty roll plates reinforce mounting points and protect the air springs from wear, and powder-coated steel brackets hold up to rust, road salt, and long seasons of abuse. From scorching heat to frozen job sites, this system is made to outlast whatever the road dishes out.

Installation That Doesn't Waste Your Weekend

Adding serious load support shouldn't mean losing a whole weekend. The precision laser-cut brackets are designed to bolt cleanly to your vehicle's existing mounting points with minimal drilling. Just smart engineering that fits the way it should, which is perfect for the DIYer. 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.

Flexible for Now, Adaptable for the Future

This kit is designed to work with your setup today and wherever your upgrades take you tomorrow. Inflate manually right out of the box - no extra parts required. Already running an onboard air system? The Alpha XD integrates easily. Planning to add a wireless controller later? No problem. With standard ports and fittings already in place, the foundation is built in, making it easy to expand your control options when you're ready.

Video Transcript for Review of Pacbrake Vehicle Suspension - Alpha XD Rear Axle Double Convoluted Air Bag Kit - PB52RV

Hi, everybody. Andy here with etrailer.com. Let's take a real quick look at this Pacbrake Alpha XD Rear Axle Double Convoluted Airbag Suspension Kit. Now, this kit has been designed to fit your 2020 and newer Chevrolet Silverado and GMC Sierra, both the 2500s and the 3500s with the two-wheel or four-wheel drive models. And this will work with your single rear wheel and dual rear wheel models, and this is going to fit trucks with the OEM fifth wheel hitch prep package. However, this is not going to fit your cab and chassis models, your Trail Boss, or AT4 trims, and this is not gonna fit trucks with the aftermarket Curt fifth wheel bracket kits.

So that's a lot of information right at the beginning, but that's why I have it there on the screen for you, just to be sure that you understood that. However, it's always good to go through our vehicle fit guide here at etrailer.com. Since this is a custom fit kit, it is vital to go through our fit guide here at etrailer.com and enter the year, make, and model of your vehicle, and then our fit guide will indeed confirm if this kit will work for you or if we have something comparable that will work for you. So as you know, when the load gets heavy, your truck is gonna need more than just those factory rear springs hanging on for dear life. These airbags are going to add up to 7,500 pounds of rear axle support, keeping your truck level and steady even when the trailer is loaded, the bed is packed, or the miles are long.

So no more rear end sag that's gonna be throwing off your braking or steering or your headlights pointing up to the sky. But as you know, every haul is different. That's why these air springs are gonna give you full control over your ride height and firmness with adjustable air pressure from 5 to 100 PSI. So if you're hauling a fifth wheel or a full bed of gravel, you're gonna be able to crank that pressure up, and then when you're unloaded and you're heading home, you can drop that pressure back down for a softer ride. With the manual inflation valves included, tuning your suspension for the day's work, it's gonna be pretty easy and straightforward.

Extreme hauling demands extreme durability. That's why these springs are built with one-inch-thick corrosion-resistant end caps that you're not gonna be able to see because I do have these kind of loosely assembled to kind of give you an idea of how they're gonna be put together. But the bags are also reinforced with 20 internal support wires for maximum strength under those heavy loads. Then these heavy-duty roll plates at the top and the bottom are gonna protect the bags from chafing and help extend their lifespan, and then these powder-coated steel brackets are gonna fight back against rust and corrosion. So this entire kit is designed for all seasons that you're gonna be driving through and any type of road conditions.

They're gonna hold up really well for you. These precision laser-cut brackets are designed to bolt cleanly to your truck's existing mounting points without welding or drilling, so they'll just mount in place with the included hardware here. And so this kit is designed to work with your setup today or wherever your upgrades take you tomorrow. Again, you're gonna be able to inflate manually with the standard air valves right out of the box. No extra parts are gonna be needed. But if you already have an onboard compressor, these are gonna connect easily to most existing setups. Or if you're planning for something like an in-cab wireless controller down the road, that's not gonna be an issue either because with this kit, you're already laying the foundation, so you're gonna make it very easy to expand your control options when you're ready. As I said, this is going to give you up to 7,500 pounds of load leveling support. However, these airbags do not actually increase your truck's weight carrying capacity, so you wanna be sure that you're not exceeding your manufacturer's recommended weight limit. If you do pick this kit up, we would love to hear back from you regarding your experience with getting these installed and using this kit, so you can share your experience with us by dropping a comment or leaving a review on this product page. And then if you do have any additional questions that I did not answer for you today, feel free to give us a call, and we'd love to help you out further. Well, I think 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.

A little extra work getting around brackets and compressing the bags to get them in, but other than that a straightforward install.

They work great.

  • Will Pacbrake Alpha XD Fit 2025 GMC Sierra 3500 With B&W Turnoverball
    Hi Rene; the Pacbrake Alpha XD # PB52RV will fit your 2025 GMC Sierra 3500. The only exception is if you have Curt 5th wheel brackets so your Turnoverball # BWGNRK1020 won't impact fitment. I also recommend adding an air compressor like the Pacbrake Bravo # PB59MV or PacBrake Bravo - XD Compressor # PB68SV so you can adjust the air pressure wherever you go from the cab of the truck. What kind of trailer are you towing?
