Frequently Asked Questions:

Can air suspension be used in the winter?

Most certainly yes! While winter does provide some unique challenges to driving, some simple maintenance on your air system can make cold climate motoring a non-event. One thing about being based in Lansing, MI, we see PLENTY of cold, snowy weather! As a matter of fact, there are a few of us that take advantage of the weather to indulge in some …ahem… sideways driving and even ice racing with our bagged cars.

What kind of maintenance is recommended for air suspension?

Overall, the only maintenance is to regularly drain the air tank to reduce the amount of water circulating through the system. We offer in-line water traps that can aide in this activity, while also significantly reducing the amount of water that gets in the system in the first place. In any case, draining the system once a month is a good rule of thumb and only takes a minute. For those of us in the northern climates, keeping your system dry is key to trouble-free running in the winter.

What is the difference between air line sizes?

In the automotive aftermarket, there are 3 common size air lines: 1/4”, 3/8”, 1/2”. The most commonly used size tends to be 1/4” because it is the easiest to rout through the vehicle. Some people like the car to move from one position to the next faster than 1/4” can do (based on the flow rate and air spring volume/pressure requirements) so they tend to choose 3/8”. The crowd that likes 1/2” will choose that size because they want the body to spring up very quickly when a valve is activated. Installing ½” lines can be the equivalent of wrestling an anaconda…

Can I install air suspension myself?

Our kits are designed for DIY people to easily and correctly install all the components if they follow our comprehensive instruction manuals. Anyone that can wire a stereo and swap suspension components has the required skills to complete a basic installation in their driveway over a weekend. However, some kits require frame modifications or welding where metal fabrication is necessary. This is NOT an area where a first-timer should learn those skills!

Where can I get air suspension installed?

Any competent shop that performs mechanical work will have the necessary tools to complete the job.

Which side of my car is the Right and Left?

The right and left sides of an automobile are determined as if sitting in the car facing forward. Thus, the left side is on the left when sitting in the car facing forward, and the right side is on the right. For American cars, the driver’s side is on the left, and the passenger sits to the right of the driver. For cars in Japan, Britain, Ireland, the Bahamas and some other former British colonies -- where they drive on the left side of the road -- the passenger sits on the left side, and the driver (along with all the driving controls) is on the right.
