Product Details

Bilstein B6 DampTronic dampers are engineered as a performance replacement for original equipment dampers on electronically controlled suspension systems. On the BMW M6, this front strut assembly keeps the factory controls and active suspension features in place while updating the damping hardware with a monotube layout and vehicle-specific valving. The result is a more precise front suspension response that supports handling, stability, and safety without changing the OE spring setup. This part cross-references BMW OE numbers 31 31 2 283 065 and 31 31 2 283 066 for the same application.

Common Issues This Part Can Address

• Excessive front-end bounce or oscillation
• Reduced steering response on the BMW M6
• Worn or leaking OE electronic strut assembly
• Uneven damping performance at the front axle
• Loss of control feel from aging suspension components

Installation Notes and Tips

Install 31-234207 on the front axle of 2006-2010 BMW M6 models equipped with electronic suspension and OE factory springs. Verify chassis code E63/E64 and confirm the upper stem and lower base cup mounting style before installation. Because this is a DampTronic unit, the factory electronic suspension controls should remain connected and functional after installation.

Quality Assurance

Bilstein tests each B6 Performance (DampTronic) damper to meet or exceed OE standards. The design uses application-specific valve settings and a monotube construction to support consistent performance in factory electronic damping applications.
