What is the lifespan of an air suspension?
2 Answers
Air suspension has a lifespan of five years. The following introduces the advantages and disadvantages of air suspension: Advantages of air suspension: A major advantage of air suspension is its ability to automatically adjust the stiffness of the springs. When driving at high speeds, the suspension automatically becomes firmer to provide better support for the vehicle, ensuring more stable driving. During prolonged low-speed driving, the suspension automatically softens to offer better comfort for passengers. In SUVs or pickup trucks equipped with air suspension, drivers can increase the stiffness of the suspension to tow heavier loads. Of course, in SUVs or pickup trucks with traditional steel springs, the vehicle body will also lower under the weight of the cargo, and compressing the shock-absorbing springs will increase the stiffness of the vehicle's suspension. Disadvantages of air suspension: As technology continues to advance, the cost of air suspension is decreasing, but compared to conventional spring suspensions, it remains relatively high, making it difficult to popularize in mid- to low-end vehicles. Moreover, the more sophisticated a system is, the more prone it is to damage. Since this system requires the use of airbags or air struts, short-term use does not significantly affect the airbags or struts. However, over time, moisture in the air can adhere to the rubber layer and cause it to crack, leading to the failure of the entire air suspension system. Additionally, small stones kicked up while driving can puncture the airbags, which may also cause the entire system to fail.
As a luxury car owner, I find air suspension systems to be quite durable, typically lasting 10 to 15 years or 150,000 to 200,000 kilometers. However, this isn't fixed—it depends on your driving habits. Frequent rough road conditions or overloading will accelerate airbag wear. From my experience, regular maintenance is crucial. For example, annual checks of the air pump and pipeline seals are essential since air leaks are the most common issue. Weather also plays a significant role: cold winters can harden rubber components, while hot summers may cause oxidation. If you notice sagging or inconsistent ride height, seek professional repair immediately to avoid bigger problems. This approach not only extends lifespan but also saves hassle and money.
