Cushion road impacts and quiet the suspension with the KYB shock mount, part number SM5334, a rear upper mount that connects the top of the shock absorber to the vehicle body. It fits many vehicles, among them the 2006-2011 Buick Lucerne, 2006-2011 Cadillac DTS and 1995-1999 Oldsmobile Aurora, and is a direct-fit replacement for the listed applications.
Over time, the vibration insulators in an original mount harden. Old mounts can then pass noise, vibration and the jarring of road bumps into the vehicle. Like other KYB top mounts, this replacement is designed to cushion those impacts and help reduce that noise and vibration.
- OE-quality replacement: KYB offers Original Equipment quality replacement components designed for each application to optimize suspension performance.
- Rubber isolation: KYB specifies rubber that helps reduce noise, vibration and harshness.
- Matched-grade hardware: matched grade studs and nuts.
- Rear upper position: cataloged for the rear upper shock mount location on the listed applications.
Signs this part may need replacing include knocking or clunking from the rear over bumps, more road noise or vibration, and cracked, hardened or separated rubber at the mount. Worn shocks or other suspension parts can cause similar symptoms, so diagnose the cause before replacing. See the Buyer's Guide tab for the full list of applications.
