INFINITI QX80 Air Strut

Air suspension strut quick guide

An air suspension strut, also known as an air strut, is a type of suspension system that uses compressed air to adjust the height of a vehicle and provide a smooth ride.

The air strut consists of an air spring and a shock absorber. The air spring is a flexible bag made of rubber or plastic that is filled with compressed air. It supports the weight of the vehicle and can be adjusted to provide a comfortable ride.

The shock absorber is designed to control the movement of the suspension system. It is made up of a piston and a cylinder filled with hydraulic fluid. When the suspension moves up and down, the piston moves through the fluid, creating resistance that helps to control the movement of the suspension.

Together, the air spring and shock absorber work to provide a smooth, comfortable ride, while also maintaining stability and handling. The air strut can be adjusted to accommodate different driving conditions and styles, providing better control and stability in rough terrain or at high speeds.

How long does an air strut last?

Generally, air struts in cars are expected to last for at least 50,000 to 100,000 miles before needing replacement. However, with proper maintenance and care, they can last much longer.

One factor that can affect the lifespan of an air strut is the quality of the component. Higher-quality air struts may last longer and require less maintenance compared to lower-quality components. Driving conditions can also impact the lifespan of an air strut. Cars that are driven on rough or uneven terrain or those that frequently carry heavy loads may put more stress on the air strut, leading to wear and tear over time.

Regular maintenance can help extend the lifespan of an air strut. This includes regular inspections to check for leaks or damage, as well as replacing the air strut if necessary.
