Elevate Your Towing and Hauling Experience with Air Lift Onboard Compressor Systems
8/6/2026
Air springs are a great way to add adjustable load support to your truck, SUV, van, or motorhome. But once you've installed them, there's another decision to make: Do you need an onboard air compressor?
Technically, the short answer is no. Air springs can be inflated manually through Schrader valves using an external air source. However, adding an onboard compressor system gives you the ability to inflate, deflate, and adjust your air springs whenever your load changes — without searching for a gas station air pump or carrying a portable compressor.
For drivers who regularly tow or haul, that convenience can make an air spring system even easier to use.
So, which onboard compressor system is right for you? Let's break down how they work, the differences between the available options, and what to consider when choosing one for your vehicle.
What Does an Onboard Air Compressor Do?
An onboard air compressor system provides an air source that's permanently installed on your vehicle and connected to your air springs.
Instead of manually filling each air spring through its Schrader valve, the onboard system allows you to increase or decrease air spring pressure using a controller or mobile app, depending on the system.
