Their seamless aluminum tanks have made inferior strength, corrosion prone, heavy, steel welded tank construction a thing of the past. Their leading-edge manufacturing process has allowed them to form their tanks from a single piece of extruded aluminum tube, creating a true seamless tank. The modern and reliable forming process on tank ports reforms the base metal inward giving a superior surface area for threading. Their standard mounting hardware gives the customer a limitless range of mounting positions and angles to accommodate most mounting situations. Seamless is proud to offer a superior, great looking product that they manufacture in Fresno, California from aluminum made in the U.S.A.

What Size Air Tank Do I Need For Air Suspension?

One of the most common questions surrounding air suspension air tanks is “what size tank do I need for my air suspension kit?” Most air suspension systems are going to utilize a 3 gallon or 5-gallon air tank. The size you will need will depend on how often you plan on using your air suspension and the type/quantity of air compressor you are using. If you plan on airing out every chance you get, you may want to get a 5-gallon tank to store more air for quicker operation. Seamless tanks are offered in various sizes and in a brushed aluminum finish.
