Description

The Monroe 40321 OESpectrum air suspension spring is designed to deliver a more comfortable ride while restoring original air ride functionality, providing a high level of control for vehicles equipped with factory air suspension systems. This air spring allows you to adjust the ride height and firmness by inflating to a specific height and pressure to smooth out the bumps on the road. Isolates impact-related noise, vibration and harshness for improved ride quality. Leak and burst tested to ensure a reliable seal with specially formulated air bellows for extended product life. Designed as a direct replacement for worn or damaged air suspension components. Part of the Monroe OESpectrum line, engineered to restore original equipment performance. Rear position application.
