The factory upper shock mount on the S550 has been a known failure point once people started lowering them and replacing the stock shocks. These UPR Billet Rear Upper Shock Mounts are a bolt in replacement that eliminates the week points and features a chrome-moly spherical bearing to stop vertical deflection that occurs in the rubber bushing in the stock mount. These reuse the factory 18mm attachment bolts to the chassis, and have three different available options for the type(s) of shock(s) you're using in your application.
PRODUCT FEATURES:
* Sold in pairs * Direct replacement * Increased tire clearance * Stainless Steel Hardware * Eliminates vertical deflection * CNC Machined from 6061 Billet Aluminum * Teflon Lined Chrome Moly Spherical Bearing * Replaces the stock upper mount known to fail INSTALLATION: Installs in 20-30 minutes.
