Our 5 gallon black air tank is the most commonly used size tank for air ride suspension. Our powder-coated black versions will provide you with a beautiful coating and rust resistance! Five gallons of air will allow you to lift your air suspension from completely flat at least 1.5 times! Most air compressors were designed around filling a five gallon tank and can fill a tank this size quickly. The 8 port design allows for several configurations when installing your air line, pressure switch, valves, gauge, or compressor feed line.
