Bilstein B1 Upper Strut Mount and Bearing Assembly for BMW F Series

Part number: Bilstein 12-283286 | Also listed as BILSTEIN-12-283286

Refresh the front end of your BMW with this genuine Bilstein B1 upper shock mount and integrated support bearing. Designed for the BMW F Series platform, this front axle top mount restores crisp steering, smooth rotation of the MacPherson strut, and eliminates creaks, knocks and vagueness from a worn top bearing. It is the perfect OE-quality replacement and the ideal partner for Bilstein dampers on daily road cars and enthusiast builds alike.

At MJ Modifications we have installed these mounts on customer cars and our own vehicles. The feedback is consistently excellent: tighter turn-in, reduced NVH and a more composed, factory-fresh feel from the front suspension.

Why this Bilstein B1 mount is a smart upgrade

• OEM-level fit and finish for BMW F Series chassis
• Restores steering precision, on-centre stability and smooth strut articulation
• Reduces front-end noises such as clunks, groans and creaking
• Durable construction for daily driving and spirited use
• Perfect match for Bilstein shock absorbers when refreshing suspension
