KYB Coil Spring Insulator P/N:SM5714
Cushion the coil spring and hush suspension noise with the KYB coil spring insulator, part SM5823. This front upper insulator is a direct-fit replacement for many vehicles, among them the 2006-2012 Ford Fusion, 2007-2012 Lincoln MKZ and 2006-2011 Mercury Milan — see the "Vehicles it fits" section for the full fitment list.
The insulator seats between the coil spring and the suspension spring seat, where its rubber pad separates the two metal surfaces to absorb road shock and keep the spring from transmitting noise and vibration into the body. As the original insulator hardens, cracks, or wears, you may notice creaking or popping from the suspension over bumps — if a failed insulator is the cause, this replaces it.
