The Basics: Firestone Air-Spring Kits

The first step when creating an air-suspension system specifically for your vehicle is choosing the correct air-spring kit for your application.Advantages of air springs steel leaf and coil helper springs:
  • Variable load-carrying capability
  • Adjustable spring strength
  • User-friendly height control

Front Application

Air springs used for front suspension applications are designed to enhance the steering and handling performance of your vehicle by supplementing or, in a few cases, replacing your vehicle's existing suspension system.

Benefits:

Levels vehicle when it is carrying heavy, front-mounted equipment (For example, a snowplow or heavy grille guard)
  • Increases rear-wheel traction, thereby improving steering and vehicle balance
  • Reduces front tire wear
  • Levels headlights, increasing visibility
  • Enhances braking and handling, even in adverse road conditions
  • Can be adjusted to accommodate varying loads
Reduces stress on vehicle's front suspension that results from extra weight
  • Reduces wear on front springs, as well as shocks
  • Lessens front-vehicle sag
Provides additional vehicle stability
  • Prevents bottoming out
  • Provides smoother ride
  • Decreases vehicle roll that results from towing trailers

Types of Kits Used in Front Applications:

Air-spring kits are vehicle-specific kits. Kit compatibility is based on your vehicle's existing suspension; not all kit types are available for every vehicle. Use etrailer.com's fitguide to find kits designed for your vehicle and its suspension.

Air Spring Kit Tips:

  • Each air-spring kit comes with vehicle-specific brackets, hardware to complete an installation and all parts necessary for manual inflation.
    • Tools required for installation will vary from kit to kit
  • Air-Helper spring kits will not increase the overall weight-carrying capacity of the vehicle
    • The weight rating stated for each air-spring kit is the weight range the spring kit is designed to support, not the weight the vehicle can support
  • How to determine the appropriate amount of air pressure for the springs based on load weight and location
    • Record the measurements from the ground to the top of the wheel well for all 4 wheels before you load the vehicle
    • Load your vehicle
    • Add air pressure to the springs until the wheel-well height returns to within a 1/2" of the original, unloaded height
      • This will be an approximate place to start
    • Take your vehicle for a drive and inflate or deflate the springs as needed to find a smooth, comfortable ride for your load
  • When the vehicle is not loaded, leave at least 5 psi in each spring to prevent damage
