Routing Your Air Suspension Lines

Completing your air suspension system install will require you to run your air lines to your air struts/shocks. This is one of the more challenging parts as this process will vary from car to car. It will take some thorough planning and possibly some drilling, so if you do not feel comfortable with this step, it is suggested to take it to a trusted professional. 

How Do You Run Air Suspension Lines?

Air suspension lines are run from your manifold to each air strut/shock. Your manifold electronically controls the air that is run to each shock and delivers the air via the air lines. Most manifolds are going to be mounted inside of the truck or in the bed of trucks, so you will need to properly map out where you want your lines to be run. For the rear suspension, you can most likely run the air lines through the trunk and into the rear shock area very easily. When it comes to running the front lines, you can choose to run your lines under the vehicle or inside the vehicle. If you are running the lines outside of the vehicle, try to run them in the frame rail to keep them protected from road hazards. You will also want to keep your lines at least 6” away from any heat sources such as exhaust components. If you are running your lines inside, try to keep them tucked away and away from any sharp objects that may rub and cut air lines.

What Type Of Air Lines Do I Need For Air Suspension?

The air lines needed for air suspension are going to need to meet a certain standard in order to be deemed safe for on-road use. It is suggested to run a nylon reinforced DOT airline in either ½” or ¼” size. This allows you to have an airline that can withstand being exposed to the elements and reduce the chances of holes being rubbed in them due to friction. AccuAir offers 50ft rolls of DOT airline to get your air suspension system plumbed correctly. 

What About Hard Lines?

If you are wanting a fancier setup, you can add some hard lines to your air suspension setup. Hard lines are usually used in more decorative trunk setups to add a more customized look. The combinations that can be had with hardlines is virtually endless and can easily set your setup apart from the crowd. These hardlines are offered in stainless, aluminum, and copper. It will be harder to work with than rubber lines, but the results are well worth the extra effort.
