SquareTank Composite Air Tank

Product Overview

This is it: The Original SquareTank. Take the core composite body air tank, pair it up with some square end caps made from billet aluminum and tie it all together with more billet connecting rods, and you've got a design that's both contemporary and minimalistic. Choose to either show off your air lines by mounting The Original SquareTank with the ports out, or flip it around to hide everything. No matter which choice you make, your tank will look amazing. The Original SquareTank is packed with options. You can customize your Original SquareTank however you like, from the size to the finishes. There are over 350 available combinations, with more on the way — and that's not including any custom decisions that you want to do on your own. This is a tank that's truly customizable, and that gives you a way to stand out from other setups. On the technical side, each of the side-specific billet end caps comes with six 3/8-inch NPT ports (three per side); two 1/8-inch NPT ports (one per side); and two 1/8-inch drain ports (one per side). That gives you a number of different plumbing options to work with, and provides plenty of flexibility for your setup. No matter which option you choose, The Original SquareTank is your best solution for a boring air suspension setup.
