Rear Lower Shock Mount Cupped Washer - E36, E46, E28, E24, E83, E85, E89

This is the large cupped washer that sits underneath the rear shock mount on E36 and E46 3-series, E28 5-series, E24 6-series, E83 X3, E85 Z4, and E89 Z4 models. This bowl-shaped washer is assembled above the rear bump stop and below the shock mount. The cup shape is mounted upside down, like a dome, so that the shock mount can rotate and twist over it. This part rarely fails but is subject to corrosion and possible cracking if the suspension has bottomed-out often. It's also overlooked during re-assembly causing the shock mount to fail.

This is a Genuine BMW cupped washer with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
