So…What Are the Parts of My Air Suspension

Keep in mind each car contains slightly different parts and compositions depending on the make and model—however, there are some parts most vehicles have inside to help you travel with luxurious finesse.

Starting off, meet the air compressor—think of this part as the heart of your air suspension system, as it pumps air to all your critical parts at opportune moments, helping ensure you smooth out bumps along the way and ride at the optimal height. However, the moment this part goes faulty, your entire air suspension system fails as you’ll no longer get the air you need flowing to your components, which leads to sagging, rough cruising, and plenty of other issues. Also, your compressor works as a tell for issues in other parts of your suspension—can you hear it running non-stop? Then you usually have a leak in your air bags.

To help send air to the right parts, your Solenoid Valve Blocks help make sure your springs and struts get the optimal bursts of air from the compressor. These parts are harder to spot issues with, but if you notice your bags or struts aren’t working right but everything seems in working order, the valve block is often the culprit.

You’ll also find other air suspension parts that vary by vehicle, like height sensors that read the distance from your chassis to the road and adjust the air sent according to how you’re cruising to help boost your performance or efficiency—perfect for adventure-driven SUVs like the Toyota 4Runner or luxury powerhouses like the Lexus LX470.

When it comes to the most critical air suspension parts after your compressor, it’s a tough call between your springs and struts. However, your air springs (sometimes called air bags) do just as the name implies—they’re literal bags that fill with air to work like a coil spring and help absorb vibrations from the road. These springs also help alter your ride height—so, whether you need an aerodynamic height from the road to reach world-class speeds in your Audi RS7 or you want a smooth and comfortable cruise in your Bentley Bentayga, you can count on your air springs to get the job done.

Your next key air suspension parts are your air struts, which work with your air springs to help dampen your ride as you cruise over rough patches, off-road, or even helps you remain in control when you attack a corner with athleticism in your BMW M4. However, once either your springs or dampers become faulty from leaks or wear and tear, you’ll feel the difference with rough drives, bottoming out when you hit high speeds, less control, and even unsightly sagging when you leave your car parked—thankfully, replacements are quick and easy—and AEROSUS covers virtually all the parts you need.
