The Bilstein B4 rear left air spring with monotube shock replaces the original air suspension unit on 2004–2008 BMW 760i and 760Li models. B4 OE replacement dampers are produced to meet original equipment standards and connect directly to the vehicle's original connectors for modification-free installation, restoring the intended ride feel and functionality of the factory air suspension system.
