Rear Shock Mount Kit - 2006-13 3-series (E9x)
If your BMW 3-series is over 5 years old and 50K miles, then you should replace the rear upper and lower shock mounts. These items degrade over time and will negatively impact your suspension. Kit includes upper support cups, sealing grommets, upper bushings, and lower mounts. Parts come from BMW or OEM supplier and are guaranteed to fit. We'll assemble them on the rear shocks for you for free.
Rear Upper Mount Kit
If your BMW has over 100K miles, or is regularly subject to snow, salt, dirt, or poor road conditions, we recommend replacing the rear upper shock mount components. These wear out over time and negatively impact your suspension.We offer the entire kit for both sides of your car at one low price, and no additional shipping if you buy it with a kit. Do it right the first time!
