• Air springs are heavy duty torsion bars coiled around an axis which compress and expand to absorb motion of the wheels. They consist of several layers of metal bound together which function as a single unit. They are used in car suspension systems and are they are considered more efficient in vibration isolation than steel springs. Air springs are useful to the air suspension system of a vehicle as they offer a smooth ride and they assist in leveling.
• As mentioned before, it can be susceptible to damage from moisture. Extremes of hot and cold can also damage the rubber. Drivers in hot or cold climates are more likely to experience air spring failures than those in mild climates. The rubber could also be punctured by road debris. Any of these problems can cause the air spring to leak air which will make the suspension sag causing the vehicle to sit uneven or, if the leak is sever enough, the vehicle may not reach proper ride height.
