Air Compressors

The Ultimate Guide to Air Ride Compressors

Air ride compressors are a key component of any vehicle that has an air suspension system. These devices allow the driver to adjust the height of their vehicle at will, allowing them to increase or decrease clearance as needed for different applications.

This blog post is designed to provide you with information about how these systems work, what they can do for you and how to test your current compressor before installing a new one.

What is an air ride compressor?

An air ride compressor is a device that pressurizes the vehicle's suspension system to adjust the height of your car. These compressors come in two different types: switch and proportional, with each type having its own distinct advantages over the other.

A switch-type compressor works by providing full pressure for as long as it's powered on; this is usually accomplished by connecting the compressor to your car's battery.

A proportional air ride system has an advantage over a switch-type in that it automatically adjusts for changes in pressure based on road conditions; this makes them ideal for trucks and other vehicles used within an industrial setting where they will be experiencing significant vibrations, shocks or impacts throughout their service life.

What can an air ride compressor do for me?

The main advantage of having your car's suspension system pressurized is that it allows you to raise or lower your vehicle as needed; this is especially important if you need additional clearance when driving over rough terrain, through deep water or other applications where the surface below might be more susceptible to damage.

How do I know if my compressor needs replacing?

An air ride compressor has a finite service life, depending on the make and model of your vehicle it can last anywhere from three to ten years before needing replacement.

If you are experiencing any unusual noises in connection with your suspension system or have noticed that it's taking longer to pressurize; these are both signs that you might need to replace your current compressor.

Testing an air ride compressor for power and leaks

Once you've determined that it's time for a new air suspension system, the first thing you'll want to do is test your old one before purchasing a replacement.

The easiest way to do this is to connect a pressure gauge between your compressor and the hose that connects it with your car's suspension system.

Once you have everything hooked up, turn on your ignition but leave the engine off; this will allow any excess air inside of the line to escape through the bottom tire before starting it back up.

If there are no air leaks between the system and the compressor, you'll see your pressure gauge jump up to its maximum level before falling back down. If this is not what happens when you start it up again, then there are air leaks in either the line or at one of its connections that will need to be repaired before installing a new compressor.


As you can see, an air ride compressor is a key component of any vehicle that has an air suspension system. These devices allow the driver to adjust their car's height as needed for different applications while also providing protection against road damage should additional clearance be necessary.
