Bilstein 03-08 BMW Z4 (E85) B6 Performance Monotube Shock - Rear

The Bilstein B6 Performance monotube shock absorber is a direct replacement for your 2003-2008 BMW Z4 (E85) rear suspension. This shock is designed to work with your car's original factory springs, meaning you can get improved handling without needing to buy new ones. It uses Bilstein's gas-pressure technology to help keep your tires firmly planted on the road, which is important for both everyday driving and those times when you need maximum grip.

This shock absorber features application-specific valving, meaning it's tuned precisely for the Z4's weight and suspension geometry. The monotube design helps dissipate heat effectively, ensuring consistent performance even under demanding conditions. You'll notice better stability, especially during lane changes or when navigating curves, contributing to a safer driving experience. Bilstein is well-known for its durable parts, and these B6 shocks are built to meet or exceed original equipment standards.
