Types of Air Bag Suspensions (Available in Guangzhou Viking)

  1. Sleeve style
  • Sleeve-style air springs are designed for lift and ride control. The internally mounted sleeve is covered by a bag, made of flexible, heavy-gauge rubber. The bag is crimped into the spring mount on one end and swaged onto the opposite end, sealing the contents inside.
  • When air is compressed into the spring, the two-piece sleeve extends, lengthening the assembly to achieve the desired ride height.
  • Sleeve style air springs are extremely well suited for applications when space is limited, and loads are light. Sleeve-style air springs are perfect for light-duty trucks, custom street rods and track cars.


  1. Bellows style
  • Bellows-style air springs are made from heavy-duty, reinforced rubber which is configured with either one or more convoluted chambers.
  • These air bags are typically larger than sleeve-style air springs, giving them greater load-handling capacity. Because of their size and shape, bellows-style air springs can lift the same weight with about half the air pressure of sleeve-style springs.
  • The most popular bellows-style air spring configurations include single, dual, and triple chamber design. Bellows air springs are great for heavy-duty applications as long as there is plenty of space for proper installation.



If you’re considering the purchase of an air bag suspension, you need to be aware of more than just the advantages. Even though you will be rewarded with great ride quality, you should weigh that against the disadvantages:

  1.    Air bag suspension cost
  •  The main roadblock to using an air bag suspension is cost. It’s got to be the most expensive suspension system on the market. If you want air bag ride quality, you’re going to have to pay for it. It’s that simple.



     2. Air bag suspension installation

  • Due to the complexity of an air bag suspension system, installation should be given to a qualified mechanic. Proper installation will ensure that safety objectives are met. Not only that, most kits require professional installation for the warranty to be honored by the manufacturer.
  • 3. Air bag suspension leaks
  • Air suspension kits are exposed to harsh road conditions. Like other suspension products, wear and tear will play a factor in the duration of every air bag suspension. Therefore, proper maintenance is required.
