Pros and Cons of Air Suspension

Pros and Cons of Air Suspension

Most modern vehicles have traditional coil springs, which you can often see behind the wheels. They work with shock absorbers to provide a smoother ride quality, and more importantly, keep the wheels as firmly planted on the ground as possible. Air suspension systems replace springs with airbags, allowing ride-height adjustments. They still require shock absorbers, but air suspension can offer significant benefits in the right applications.

Pros of Air Suspension Systems

Air suspension can bring a range of improvements to a vehicle’s ride quality and capability, though it isn’t perfect for every situation.

· Ride quality: Air suspension can be more effective at absorbing bumps from road imperfections, such as potholes. Many of the latest systems offer adaptive damping, which works with the vehicle’s computer system to adjust firmness and rebound speeds, providing a better ride on a wide range of road surfaces and terrain.

· Better handling: Adaptive air suspension can firm up when needed, helping reduce body roll and movement in corners. It may also help improve steering responsiveness and stability for some vehicles.

· Ride-height adjustments: Many air suspension systems give users the ability to raise and lower the vehicle’s ride height. That can be useful in off-road situations, but it can also offer an aesthetic benefit because many people prefer the “slammed” look when the vehicle is parked.

· Automatic load leveling: Some full-size pickup trucks and SUVs have load-leveling air suspension, which compensates for heavy payloads by boosting the rear suspension height and firmness. These systems also make towing much safer and more stable.

· Reduced wear: Fewer vibrations and a smoother ride place less wear on a vehicle’s body components, which can extend its life.

Cons of Air Suspension

There are plenty of reasons to choose air suspension, but there are some downsides to consider before jumping in.

· Repair costs: Air suspension systems rely on airbags, which can degrade over time, causing leaks. Those leaks can cause the suspension to sag, which is why you might see some Land Rovers and Mercedes-Benz models sitting on the ground after a suspension failure.

· Weight: Air suspension systems require a compressor and other components to inflate and deflate the bags, adding weight and complexity to the vehicle. The added heft can impact fuel economy.

· Purchase cost: Automakers typically charge more for air suspension or make it available only on higher trim levels, which raises the cost of entry higher compared to vehicles with traditional suspension systems.
