3.0 GALLON HEAVY-DUTY STEEL AIR TANK: Classic vehicles are heavy, and air suspension systems for these builds require real volume. When space is limited, the 3.0-gallon heavy-duty steel air tank is the ideal solution for tucked-away mounting. These tanks are designed to fit perfectly in the tight compartments of older wagons, spare tire carriers, or under the bed of a C10 where a larger tank simply won’t go.
PRO-TIP: For heavy classic vehicles, running two of these tanks is the preferred setup. This configuration provides the high-volume capacity needed to get the front end up in a lick of time while allowing the air storage to be split between quarter panels or other unused spaces. Featuring a 7-port configuration, this tank is the industry standard for classic car air ride. Even in a compact size, there is no compromise on plumbing. These ports provide the flexibility to run lines, dual compressors, pressure switch, quick connect, etc. where they are needed for a clean, professional install.
STEEL IS REAL: THE TRUTH ON TANKS.
While these tanks are genuine steel, the common claim is that an aluminum tank is “required” because it doesn’t rust. The reality is that it’s not just about the tank rusting. It’s about the rest of the air system being contaminated with that murky water that builds up in any tank if it isn’t maintained.
Think about the classic vehicle on the rack right now. The frame isn’t aluminum; it’s steel. If a frame sits in a river for years, it’s going to rust. The solution? Keep the frame out of the water.
The same rule applies to air ride. Whether the tank is aluminum, stainless, or regular steel—it must be kept dry. That is why “Touch of a Button” Tank Drain is the recommended standard. It’s moisture management with the flick of a finger instead of laying on a back in a trunk or under a truck with a wrench and a rag on a Saturday morning.
Why lay on your back in a trunk or crawl under a truck to drain your tank when you could just push a button? Check out our Electric Tank Drains to keep the system dry and the weekend open.
