The Air Spring is part of your car's air suspension system. It is needed for adjusting the vehicle's ride height. It has a cylindrical chamber where air is compressed by increasing the pressure. When the car is loaded with heavy weight, the vehicle's ride height is increased by applying additional air to the spring. The air spring is located at both the front and rear axles. It has four layers: the outer cover and inner liner made of rubber and two ply layers made of reinforced rubber.
The air spring has a bead plate, piston/bellow and stud. The air from the chamber is released when there is an extension in the springs. This action decreases the pressure in the air. The process of filling and emptying the cylindrical chamber neutralizes the air springs, allowing your car to ride at a constant height. If your car's air springs are not providing the needed springing action, get them checked out by a certified mechanic as quickly as possible. You should replace worn out air springs quickly to avoid further damages. Car Parts Warehouse stocks a wide variety of air springs at unbeatable prices, and free shipping!
