Bilstein B4 22-158819 Left-Hand Front Damper for BMW Z3 E36/7 E36/8 Roadster and Coupé

Bring your Z3 back to how Bavaria intended. The Bilstein B4 22-158819 is the left-hand front suspension leg for BMW Z3 models built on the E36/7 and E36/8 platforms from 1995 to 2003. This gas-charged, twin-tube MacPherson unit is engineered to OE standards, restoring crisp steering feel, stable braking and supple ride quality without altering ride height. If your nearside front feels bouncy or vague, this is the straightforward fix that gets your car driving tight and tidy again.

We have fitted countless B4 units on customer cars and our own builds. Feedback is consistently brilliant for everyday comfort, confident control on British B-roads and long-term reliability. It is the smart choice when you want factory-spec damping performance with the durability and consistency Bilstein is known for.
