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 drops in as a direct-fit replacement for the 2006-2012 Ford Fusion, 2007-2012 Lincoln MKZ, 2006-2011 Mercury Milan, 2006 Lincoln Zephyr, and 2004-2008 Mazda 6 — see the Buyer's Guide tab for engine-level fitment.
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.
