2.5 Gallon Aluminum Air Tank; (4) 1/4" face ports; 6" D X 20" L, light weight, 200PSI maximum operating pressure. Customizing your car is all about choices and when it comes to your air tank, that should be no different. With our aluminum tanks, we can offer you a wide variety of sizes, port configurations, and finishes. Our extruded aluminum tanks are now available in raw aluminum or in a super high quality polished finish. If the look of aluminum is not really your thing, simply take your tank to your favorite powder coating or anodizing shop for a show stopping finish. Whether you decide on a splash of color or bare aluminum, you cannot go wrong with the look of an Air Lift Performance tank! No matter the size of your mounting area, we have a tank that is sure to fit. Ranging from sizes of 2.5, 4, and 5 gallon these tanks will hold just the right amount of air you are looking for. With our 4 gallon tank you can even choose different port configurations to really customize your set up. Another huge benefit with our aluminum tanks is the tremendous weight savings you will see over a standard steel tank. Less weight can mean faster lap times and improved weight distribution.
