If you're installing an air helper spring system on your truck or SUV, having a dedicated air tank is a smart move.

This tank is well-built with a steel construction that's coated inside and out with a baked black enamel finish to resist corrosion. It's tested to SAE J10 specifications and can handle up to 150 PSI, which is twice its working pressure. You get three 1/4-inch NPT ports and two 1/8-inch NPT ports, giving you plenty of options for connecting air lines, gauges, or compressors.

With its 7-inch diameter and 20.75-inch length, this tank offers a good balance of capacity and size for many applications. It's a solid option for ensuring your air helper springs perform as they should.
