3 Gallon Vs 5 Gallon Air Tanks

When gathering the parts for your air suspension system, a few components will have various configurations for you to choose from. Your air suspension air tank is one of those components and will usually be offered in 3-gallon or 5-gallon sizes. Obviously, the size will be a big factor here, as a 5-gallon tank is much larger than a 3-gallon tank, but there are a few other things you need to consider before making your purchase.

What Factors Determine What Size Air Tank I Need?

When choosing between a 3-gallon or 5-gallon air tank for air suspension, you need to consider your mounting space, how often you use your system, and, if it's important to you, the aesthetics of how it looks in your vehicle. Let’s take a closer look at each of these factors to give you a better idea of what to look for.

Mounting Space

The first thing you will want to consider is your mounting space. This space is where you want to mount your tank, so you need to consider where your compressor and other air suspension components will be mounted. Sometimes, a 5-gallon tank is too large for some vehicles, so a 3-gallon tank must be used. For those with extra room to spare, a 5-gallon tank is a great option as you will have more compressed air on demand to use in your system. The dimensions of our air tanks can be found on our product pages to give you a better idea of how much room you will need for your air tank.

How Often You Use Your System

If you often plan on using your air suspension system, a 3-gallon tank may not be enough to feed your air struts as quickly as you want. In this case, you will most likely need a 5-gallon tank to keep up with the constant use of your system. If you only use your air suspension system every now and then, or if it is on a car or truck that only gets driven to and from car shows, a 3-gallon tank should suffice. 

3-gallon tanks are also recommended for smaller vehicles that do not weigh much, whereas a 5-gallon tank will be best for your larger vehicles, trucks, or SUVs.


Lastly, if you want your air suspension system to be presentable, such as at a car show or your local car meet, you will want to shop based on aesthetics. Sometimes, a 5-gallon tank will look more symmetrical than a 3-gallon tank in trunk setups. While this is not the most important factor, planning out how your air suspension system looks can give you a quick and easy answer as to which air suspension tank you want to go with.
