It supports the vehicle's weight and provides adjustable ride height by inflating or deflating. When the lift axle is not needed, the bag is deflated to raise the axle off the road, reducing tire wear and improving fuel efficiency. A worn or leaking air spring can cause sagging, poor ride quality, or failure to lift the axle, so it should be replaced promptly.
