Features to know about

Level the Rear Under Heavy Loads

Typical Alpha HD Pro installation shown. Vehicle-specific brackets vary by application.

When trailer weight or a heavy cargo load settles your van onto its rear suspension, squat and extra body movement can make the van feel less controlled. The two adjustable rear air springs add supplemental support to help reduce sag, sway, and bottoming while letting you tune the suspension to the weight you're carrying. With up to 5,000 lbs of load-leveling capacity, you can add only the pressure the load calls for instead of treating maximum pressure as the default. Your van can sit closer to level and remain more controlled while carrying or towing substantial weight.

Add Support, Then Drop to 0 psi

A van that tows one day and runs empty the next doesn't need the same rear-suspension support all the time. Internal jounce bumpers let you add air when your trailer or cargo is aboard, then reduce the air springs to 0 psi once that load comes off. Those internal jounces also protect the air springs against bottoming when suspension travel is used up. You get the support your van needs under weight without having to keep air in the bags simply to protect them when you're driving empty.

Corrosion Resistance Where Exposure Hits Hardest

Suspension hardware lives where road spray, dirt, and weather reach it, so material choices matter underneath your van. 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 van.

Custom Installation

You'll start by measuring your van'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 air spring assemblies mount between the frame and axle using vehicle-specific upper brackets and axle straps below, with brake and ABS line clearance checked carefully as everything is positioned and aligned. Once the springs are secured, you'll install the passenger-side exhaust heat shield, then 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 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 if your towing or hauling setup changes frequently. You can add a Pacbrake Bravo Wireless Air Control Kit (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.
