The Upgrades: Firestone Air Command Kits

Tired of stopping at a gas station or using a portable air compressor to inflate your air springs? Adding an Air Command Kit to your vehicle's suspension system allows for simple, convenient inflation of your air springs without getting out of the cab of your vehicle. The kits also provide precision control of air spring pressure and offer options for inflating other accessories.

Standard Air Command Kits

Upgrading your air suspension system with an air compressor and in-cab gauges allows you to control your springs from within your vehicle. Air Command kits come with all the components needed to upgrade your suspension system. Air system components vary from kit to kit.

Air Command Kits include:

• Standard air-pressure gauge and valve installed in cab allow you to constantly monitor your air spring pressure
  • Inflate and deflate air-spring pressure with the flip of a switch
  • Air tubing must be run to control panel in the cab
• Compressor
  • See individual kit for type of compressor included
• Air tank (included in some heavy duty kits - not always necessary)
  • See kit for tank size
• All air tubing, wiring and hardware necessary for installation

Types of Kits

• Pneumatic Activation kits:
  • Single gauge
    • Inflates 2 springs equally
  • Dual gauge
    • Inflates 2 springs individually or 2 separate sets of springs (for example, 2 front springs can have different pressure levels from 2 rear springs on the same vehicle)
    • Ideal for accommodating loading and unloading
  • Quad gauge
    • Inflates 4 springs individually
• Electric Activation kits:
  • Single gauge
    • Inflates 2 springs equally
  • Dual gauge
    • Inflates 2 springs individually or 2 separate sets of springs (for example, 2 front springs can have different pressure levels from 2 rear springs on the same vehicle)
    • Ideal for accommodating loading and unloading

Digital Air Command Kits

Digital air command systems have a digital control panel that is installed in the cab of the vehicle, allowing you to constantly monitor and adjust your air spring pressure. Digital control panels also detect and alert you when your air spring pressure is too high.

• In-cab digital gauge allows continuous monitoring of your air spring pressure
  • Uses digital signal units to read air spring pressure
  • Does not require air tubing to be run to the cab
  • Gauge flashes red when air spring pressure is too high
• System stops inflating automatically when springs reach 120 psi and stops deflating when springs reach 5 psi
  • Protects your springs from over inflation and under inflation
• Works in conjunction with existing air springs
• Kits include standard-duty air compressors
• See individual kit for information on air tanks
  • Some kits are compatible with tanks up to 1-gallon
  • Some kits are not compatible with tanks
• Available types:
  • Single gauge
    • Inflates 2 springs equally
  • Dual-gauge
    • Inflates 2 springs individually or 2 separate sets of springs (for example, 2 front springs can have different pressure levels from 2 rear springs on the same vehicle)
    • Includes all air tubing, wiring and hardware necessary for installation

Wireless Air Command Kit

Wireless air command systems allow you to inflate and deflate your air springs with a remote control from inside your vehicle or up to 50 feet from the vehicle.

• Inflate air springs using a remote control
  • Control is either a remote with a digital screen or a key fob
  • Up-and-down arrows indicate buttons for inflation and deflation
• Wireless remote:
  • Has 3 programmable pre-settings
  • Allows you to visually inspect the air springs as they are inflated or deflated, helping you to find the best ride height
  • Does not require air hose to be run into the cab of the vehicle
• Kit includes an air compressor
  • See individual kits for type of compressor included
• Not compatible with air tanks
• Available types:
  • Single function
    • Inflates 2 springs equally
  • Dual function
    • Inflates 2 springs individually or 2 separate sets of springs (for example, 2 front springs can have different pressure levels from 2 rear springs on the same vehicle)
    • Includes all air tubing, wiring and hardware necessary for installation

Automatic Air Command Kits

An automatic-inflation air kit allows you to set a preferred vehicle-ride height. When a load is added to or removed to the vehicle, the air-spring system will automatically inflate or deflate the air springs to the pre-set, user-determined height.

Pneumatic Activation

• Changes to and adjustments of the height-control valve manipulate the amount of air that flows in and out of the springs, inflating and deflating as necessary
  • Air hoses run through the height-control valve
  • When the control valve is pulled or pushed out of its original position, the system automatically inflates or deflates springs to compensate for the change in load
  • During deflation, the air exits the system via the exhaust hose
• Available types:
  • Single gauge
    • Inflates 2 springs equally
  • Dual gauge
    • Inflates 2 springs individually or 2 separate sets of springs (for example, 2 front springs can have different pressure levels from 2 rear springs on the same vehicle)
    • Ideal for accommodating loading and unloading

Electric Activation

• Changes in the ride height of the vehicle are detected by the height sensor, which then sends an electronic signal to the compressor to inflate the springs
• Includes a compressor
• Does not require a tank
• Available as single-gauge system
  • Inflates 2 springs equally (one set of springs equally)
