It replaces a traditional steel spring to provide a smoother, height-controlled ride by supporting the vehicle's weight with compressed air. You generally replace it when the original bag is cracked, leaking, or no longer holds air, leading to a sagging ride height or a rough ride. This aftermarket unit is built with a plastic base for reduced weight and corrosion resistance, meeting OEM dimensions for a direct drop-in fit.
