The Bilstein B4 rear twin-tube shock is an OE-replacement for 2006–2010 BMW 530xi and 535xi models. It restores original ride comfort and handling by meeting or exceeding OE standards, offering precise construction and high power reserves for consistent damping. Use these dampers when returning a vehicle to factory ride characteristics without altering handling balance.
