BMW Air Suspension - Parts List

The BMW is arguably one of the most versatile vehicles for car enthusiasts across the globe. From modded out 3 series to pristine M3s to family-friendly BMW X5s, the BMW vehicle lineup offers a little bit of everything for everyone. One of the most popular mods for those looking to take their BMW to another level, literally, is air suspension. A bagged BMW turns heads at every car show and is a great way to get adjustable suspension on your vehicle. Today, we are going to look at what you need to build your BMW air suspension system. 

What Do I Need To Add Air Suspension To My BMW?

Adding air ride to your BMW is not the cheapest way to lower your vehicle, but it is one of the most versatile when it comes to dialing in your suspension. Airbag suspension systems can be purchased as a kit or pieced together using various high-quality components. 

Air Compressor

The first component we are going to look at when building an air suspension kit is the air compressor. The air suspension compressor connects to your battery and compresses air to be supplied into your air suspension system. You can use one or two compressors in your system, depending on how much air you plan on using.

Air Tank

To store the air created by the compressors, you are going to need an air tank that holds enough air for your system. These are usually offered in 3 and 5-gallon configurations and in a variety of different shapes and finishes.

Air Lines

To transfer air from the air tank to the air struts or air springs, you will need plenty of air line. Air line connects from the air tank to the air manifold and from the manifold to each air strut. Air lines run in and out of your vehicle along body lines to protect them from becoming punctured. 

Valve Manifold

In an air suspension kit, the valve manifold is responsible for distributing the air to each of your airbags. Mounted between the air tank and the air struts, the valve manifold contains valves that release air to each strut on demand. These manifolds are essential to the performance of your air suspension system and will be connected to the controller or ECU of your system. Choose between 2 and 4 corner manifolds for your specific setup.

Management System

In order to control your air suspension system, you will need an air management system. AccuAir specializes in offering the highest-quality air suspension management systems on the market. Choose from a variety of different management systems that offer Bluetooth and wifi capabilities for mobile control of your air suspension system. 

Air Struts/Air Springs

When switching over to air suspension, you are going to need to replace your factory shocks and springs with air struts or air springs. These air struts are very similar to factory MacPhearson setups, but instead of springs, they have rubber bladders that inflate with air to raise a vehicle and deflate to lower a vehicle. 

Water Traps/Filters

While optional, we highly suggest adding a water trap or filter to your air suspension system. Since your air suspension system uses compressed air, you run the risk of having moisture develop in your air tank when the compressed air is stored. A water filter, or water trap, can help catch this water before it enters your air lines where it can freeze or cause mechanical issues.

Ride Height Sensors

Another optional accessory to an air suspension system is ride height sensors. Ride height sensors can be installed on most AccuAir systems and allow you to pre-program specific ride heights for easy, one-push leveling to your desired height.
