Bilstein B4 Front Right Twintube Strut Assembly - BMW Z4 (E85/E86) 2003-2008

Bilstein B4 dampers are the OE replacement line, engineered to restore the ride quality, handling and safety a car had when it left the factory while meeting or exceeding the original equipment standard. This is the front right twintube unit for the Z4, supplied as a complete strut assembly rather than a bare damper, so it goes in as one piece. Bilstein builds it with high power reserves for a margin of safety when the suspension is worked hard, and holds precise construction tolerances, which is why the B4 is the line to choose when the goal is factory feel restored rather than a firmer setup.
