Bilstein B1 Front Strut Top Mount Support Bearing 12-248605 for BMW E24 E28 E30 E34 Z1 (3/5/6 Series, incl E30 M3) - OEM Quality Front Axle Shock Absorber Mount

Bilstein 12-248605 Upper Suspension Mount and Bearing for BMW E24, E28, E30, E34 and Z1

Restore tight, precise steering and a refined ride on your classic BMW with this Bilstein B1 upper strut bearing and front suspension mount, part number 12-248605. Built to factory specification for longevity and quiet running, it pairs perfectly with Bilstein dampers and standard shocks alike, making it the smart choice when refreshing tired front-end components on E30, E28, E34, E24 and Z1 platforms.

At MJ Modifications we have fitted this component on customer cars and our own builds, and the feedback is consistently strong. Turn-in feels sharper, unwanted front-end noise is tamed and the steering remains consistent mile after mile. If you are renewing springs or dampers, replacing the front top mount and bearing at the same time delivers the best result for stability and comfort.
