Conquer the road ahead with the help of Air Command Heavy Duty Air Compressor System with Single Analog Gauge! With this system you can easily inflate or deflate your air springs with the touch of a button. It provides an on-the-spot air source to your vehicle's suspension system, letting you modify your springs to match the load and driving conditions. Offering distinct advantages, easy installation is chief among them, so you can get it hooked up and hop on the road in no time. Connect one wire to the compressor and three to the vehicle. The wiring harness and air lines can be plugged into the same side of the unit for uncluttered routing of power supply and lines. With the Air Command system properly installed you can make pressure adjustments by pressing a single button. You'll get side-to-side leveling, real-time pressure readout, and dual left and right psi and pressure control readouts. This system's optimized display can be seen morning or night, without straining your eyes. Before installation, familiarize yourself with the instruction manual and identify all of the components to help make sure you get maximum performance from both your air springs and Air Command Heavy Duty Air Compressor System with Single Analog Gauge. The steps differ if installing with a new air spring kit or adding to an existing one. Backed by Firestone Airide's 2-year warranty against defects in workmanship and materials.
