Detailed Description

Bilstein B6 Performance dampers are built as an OE damper upgrade for drivers who want improved handling without changing the factory spring setup. The monotube construction helps deliver more precise damping control, and the valving is tuned for the specific application to support better steering feel and front suspension response. This makes 35-244059 a practical replacement for the front left corner on select BMW performance models.

This part cross-references OE numbers 31 31 2 284 785 and 31 31 2 284 945 for the same application. It is a strong fit for BMW M3, BMW M4, and BMW M2 owners seeking a front left strut assembly that matches factory spring geometry and non-electronic suspension setups.

What It Helps Address

• Excessive front-end bounce or float
• Reduced steering precision during cornering
• Uneven damping response from a worn OE strut
• Loss of stability over rough pavement
• Front suspension wear that affects ride control
