Pacbrake Vehicle Suspension - PB58XV

  • Air Springs
  • Towing/Load Leveling
  • Rear Axle Suspension Enhancement
  • Pacbrake
  • Extra Heavy Duty
  • Suspension Only

Demanding trailer, camper, or payload weight can leave your truck squatting and less controlled. These air springs add up to 7,500 lbs of leveling support to reduce sag, sway, and bottoming, while internal jounces let you run 0 psi unloaded.


Highlights

  • Custom Fit for Your Truck: Vehicle-specific brackets and hardware position the air springs for your truck's rear suspension.
  • Level Demanding Rear Loads: Up to 7,500 lbs of supplemental support helps reduce rear sag with substantial trailer, camper, or payload weight.
  • Match Support to the Load: Adjust air pressure to suit changing towing and hauling loads instead of running one fixed level of support.
  • Run at 0 psi Unloaded: Internal jounce bumpers let you bleed the air springs down to 0 psi once the extra load comes off.
  • Built for Life Under Your Truck: Stainless steel hardware and braided air lines add corrosion resistance where the system faces road spray and weather.
  • Upgrade Your Air Control: Add a compatible onboard compressor or control system for more convenient pressure changes.

Features to know about

More Support for Demanding Rear Loads

Your truck can feel composed empty, then change quickly once substantial pin weight, a slide-in camper, or a heavy work payload settles onto the rear suspension. The two adjustable rear air springs provide up to 7,500 lbs of load-leveling support to help bring a sagging rear back toward normal ride height while reducing sway and bottoming under load. Instead of treating that capacity as a target, you can tune the air pressure to the weight your truck is actually carrying.

Heavy-Duty Support That Backs Off When You Do

A truck built for serious towing or hauling may still spend plenty of miles without that weight on the rear suspension. Internal jounce bumpers let you increase air pressure when a substantial load calls for more support, then reduce the air springs to 0 psi when the extra weight comes off. Those internal jounces protect the air springs against bottoming when suspension travel is used up, so you don't have to maintain air pressure simply to protect the bags during unloaded driving. The result is adjustable support that can work around both sides of your truck's job instead of treating every mile like a loaded one.

Corrosion Resistance Where Exposure Hits Hardest

Suspension hardware lives where road spray, dirt, and weather reach it, so material choices matter underneath your truck. This kit uses braided stainless steel air lines along with stainless steel fittings, Schrader valves, roll plates, and mounting hardware to add corrosion resistance throughout key parts of the system. That extra durability is focused where it matters, helping the hardware you rely on for load support and pressure adjustment stand up to the environment beneath a working truck.

Custom Installation

You'll start by measuring your truck's stock ride height and checking tire-to-frame clearance before removing the factory jounce bumpers, with rear-wheel removal optional if you want more working room. The upper brackets begin at the existing jounce-bumper mounting locations, then additional support brackets are positioned against the frame before drilling the mounting holes that finish securing them in place, with fuel lines temporarily moved on the driver side for clearance. Once the air spring assemblies are positioned between the frame and axle, the lower brackets secure around the axle with straps, with emergency-brake-line clearance checked as everything is aligned and torqued. You'll then install the passenger-side exhaust heat shield and route the braided stainless steel air lines with enough clearance and slack for suspension movement before mounting the Schrader valves where they're easy to reach. Adding air bags is a job experienced DIYers can handle, but this installation does require drilling into the frame, so if you would rather leave it to a professional, we can help you find an installer near you.

Upgrade Your Air Control

The included Schrader valves give you everything you need to adjust the air springs manually, but pulling out an external compressor can get old when your truck regularly switches between demanding loads and unloaded driving. You can add a Pacbrake Bravo Wireless Air Control Kit with XD Compressor (sold separately) to adjust pressure from your phone, check live pressure, and save presets for loads you come back to regularly. Also, you'll be able to choose between filling both air springs together or controlling them independently when the load isn't even side to side. It's an optional upgrade, but one that makes the adjustable part of an air-spring system much easier to use regularly. And it's not the only solution available. There are a variety of compressor options from Pacbrake that might be the perfect fit for your setup.

Video Transcript for Review of Pacbrake Vehicle Suspension - Towing/Load Leveling Stainless Steel - PB58XV

Hi, everyone. Steven here with etrailer. Today we're taking a look at our Pacbrake Alpha Airbag Suspension Kit with Internal Jounces, rated at 7,500 pounds of low leveling capacity, featuring the stainless steel hardware upgrade kit. Now folks, this is gonna fit 18 through 25 Ram 4500s, and the 18 through 26 Ram 5500s. So make sure you're double checking the fit guide to be sure you're getting the right set and the right parts for your specific vehicle. Now I mentioned before that these have an internal jounce, and I do wanna go ahead and throw up a quick cutaway photo of an airbag with an internal jounce just so you kinda get the concept if you're not sure or ever seen it.

And that is a flexible polyurethane bumper inside of there. Now air suspension, this is the rear suspension for those vehicles. We do offer the front and the rears in some vehicles, but this is the rear, and this is designed to improve your load support and your ride control. Now I just have everything kind of loosely fitted on the table, loosely stacked together. Obviously, you're going to be bolting everything down or if you don't wanna tackle it yourself, you can use our dealer locator tool at etrailer and we can find somebody in your area that we're affiliated with that can do the installation for you as well.

Now these, again, have the upgraded stainless steel hardware. All these different plates here that you see are stainless steel, the stainless steel braided airlines. You are gonna get a whole lot of other stuff that I just don't have space here for on the table. And I do wanna throw up a quick image of the hardware kit and all the parts you're gonna get. Now that being said, you're probably gonna get some other plates that are not stainless steel, and another hardware package that isn't a stainless steel.

It just depends on how they're packaged it from the factory. We've seen a lot of 'em come through with both. Just make sure that you're using the stainless steel set. The other ones are gonna be extra parts for you. And as always, if you have any questions, you can always reach out to us as well here at etrailer, and we can assist you with any questions you have as well.

Now airbags are going to help, again, reduce that rear end sag, body roll, bottoming out when you're hauling. The neat thing with that internal jounce is these can operate at zero PSI whenever you're unloaded and they're gonna still maintain your factory ride quality. Now again, 7,500 pounds of load level capacity. So a lot of times if you get hooked up and you're squatting in the rear end, these will help get you back up into that OE ride height, that same ride quality, but they're also gonna cushion everything and kind of improve that OE quality as well. So I do love airbags. They're a great option for you. Keep in mind, this is just the bag, and, you know, what you see here on the table and the pictures I showed you, there's no compressor included. We do sell those separately. There's no onboard air tanks. Again, we sell those separately as well. If you want a complete package, you can check all that out here at etrailer as well separately. And again, reach out to us if you have questions about, you know, "Hey, I don't know what I need. Here's what I do every day. Here's exactly what I'm hauling all the time." Or, "Here's what I haul, you know, a couple times a month." And we can help find something that's gonna fit your needs that's gonna best suit you as well. Well folks, I think that's gonna wrap up just our quick look together today. I'm Steven, as always, reach out, again, if you have any questions, and have a great day.
