While your car, truck, or SUV depends on Firestone Ride-Rite ™ air springs to deliver in-cabin comfort, confidence, and control, you turn to Firestone Air Command ™ products to take your experience to the next level. You count on air accessories like the Air Command Heavy-Duty Air Compressor System with Single Analog Gauge. The Air Command Heavy-Duty Air Compressor System with Single Analog Gauge makes inflating or deflating your air springs easy 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. Firestone Air Command Heavy-Duty Air Compressor System with Single Analog Gauge, in particular, features a handful of distinct advantages. The Air Command Heavy-Duty Air Compressor System with Single Analog Gauge's 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.
