Installing an Air Suspension Compressor on 31 May 2024: A Guide for Beginners

You finally bought that sweet lifted truck you’ve been dreaming about for years. But now that beastly suspension is beating you and your passengers to a pulp. Every bump in the road feels like you’re four-wheeling through the Rubicon. Time to civilize that rig with a little air suspension magic. We’ll walk through everything you need to know to install an air compressor and make your truck glide down the highway like it’s floating on a cloud. No experience required – just the willingness to get your hands dirty. In less than a day, you’ll be cruising in comfort. Let’s get started!

What Is an Air Suspension Compressor?

An air suspension compressor is what provides air to your vehicle’s air suspension system. It compresses air and sends it to inflate the air bags in your suspension. These air bags essentially replace your conventional steel springs.

The air suspension compressor allows you to adjust the air pressure in the bags using a control panel in your vehicle’s interior. This gives you an adjustable suspension that can be softened for a cushy ride over bumpy terrain or stiffened for responsive handling on curvy roads.

How Does It Work?

The air suspension compressor draws air from outside your vehicle into its cylinder. A piston then compresses this air, increasing its pressure. The compressed air is sent through a network of air lines to inflate the air bags in your suspension system.

Sensors monitor the air pressure in the bags and relay this information to the compressor. If the pressure is too low, the compressor will turn on automatically and pump air into the bags until the proper pressure level is reached. You can also manually adjust the pressure up or down using the control panel to suit your needs or preferences.

Installing an Air Suspension Compressor

If your vehicle did not come with an air suspension system, you’ll need to install an aftermarket kit to add this feature. The main components you’ll need are the compressor, air bags or air springs for your suspension, an air tank to store compressed air, control arms and brackets, air lines to route air from the compressor to the bags, a pressure sensor, and an in-dash control panel.

Installation involves mounting these components, routing air lines, wiring the electrical system, and calibrating the sensors. For most vehicles, it should take between 6 to 8 hours for a professional mechanic to fully install an air suspension kit. The total cost will depend on the specific components used but expect to pay between $2,000 to $5,000 for parts and labor.

How to Install an Air Suspension Compressor on 31 May 2024

Gather the necessary tools

You’ll need some basic tools for this job like wrenches, screwdrivers, wire cutters, and crimpers. Don’t forget things like zip ties, mounting hardware, and wiring. An air compressor installation kit will have most of what you need to get started.

Find a good location

Pick a spot in your trunk, under the hood, or in your wheel well to mount the compressor. It should be in a spot that’s dry, easy to access, and away from extreme heat. You want adequate ventilation and space for the compressor to do its job.

Install the compressor

Bolt or weld the compressor into place, then attach the air lines. Most kits will have color-coded air lines to make installation easy. Attach the red line to the inlet port and run it to your air source. Attach the blue line to the outlet port and run it to your air suspension control valves.

Wire the compressor

You’ll need to wire the compressor to a 12V power source in your vehicle like the battery or fuse box. Connect the black ground wire to bare metal in your frame. The red power wire should run to a fuse or relay for protection before connecting to your 12V power source. Add an inline fuse for safety.

Test and enjoy!

Turn on your vehicle to test the new compressor. Check for any air leaks in the system and tighten fittings as needed. Once everything checks out, you’re ready to enjoy the smooth ride of your air suspension! Your compressor will automatically turn on and off to regulate the air pressure for optimum performance.

FAQs About Air Suspension Compressors

How do air suspension compressors work?

Air suspension compressors pump air into your vehicle’s air springs or air bags. They take the air from around your vehicle and compress it to a higher pressure so it can inflate the air springs. The air springs then provide a cushioned, adjustable ride for your vehicle.

Do I need an air compressor to install air suspension?

Yes, an air compressor is required for air suspension systems to function. The air compressor pumps air into the air springs or air bags in your suspension system. Without an air compressor, air suspension would not be possible.

What size air compressor do I need for air suspension?

For most air suspension systems, a 1/2 to 3/4 horsepower compressor with a tank of at least 3 gallons should work well for light to moderate driving. For heavy-duty use, a larger compressor, like 2 to 3 horsepower with a 5 to 10 gallon tank, is recommended. The specific size depends on your vehicle’s weight and how much you will adjust the suspension. It’s best to follow the recommendations in your air suspension kit’s instructions.

Do I need an air tank with the compressor?

An air tank is not strictly required but is highly recommended for most air suspension setups. The air tank acts as an air reservoir, storing compressed air from the air compressor. This allows the compressor to turn on and off as needed to keep the tank filled, rather than running constantly to supply air directly to the air springs. An air tank makes the air compressor more efficient and prolongs its lifespan.

How do I install an air compressor for air suspension?

Installing an air compressor for air suspension will depend on your specific vehicle and kit. In general, you will need to select a suitable location for mounting the compressor and air tank, often in the trunk area or under the vehicle. You will also need to connect the air compressor to your vehicle’s electrical system to provide power. Then, plumb air lines to connect the compressor, air tank, pressure switch, gauges, and air springs. Be sure to follow all instructions carefully for your particular air suspension kit.


So there you have it, a step-by-step guide to installing an air suspension compressor all by yourself. While it might seem intimidating at first, taking your time and following each step carefully will lead to a successful install. Just remember to use jack stands for safety, get all the right tools and Auto parts ahead of time, and don’t be afraid to get your hands dirty. This could be the start of a fun new project car with a super cool air suspension. And when your friends ask how you did it, you’ll be able to proudly say you followed this guide and did it yourself! Hopefully this gives you the confidence to get started on your air suspension dreams.
