KYB Coil Spring Insulator P/N:SM5714

Quiet the squeaks and vibration coming through your suspension with the KYB coil spring insulator SM5714, a front lower spring seat insulator (also listed as a spring seat insulator) that cushions the coil spring where it seats against the suspension. It fits many vehicles as a direct-fit replacement, among them the 2006-2016 Dodge Charger, 2005-2016 Chrysler 300 and 2008-2017 Dodge Challenger. See the Buyer's Guide tab for the full list of applications.

• Application-specific fit: an OE-quality replacement component designed for each listed application.
• Quieter ride: cushions the coil spring at the seat to help reduce squeaks, rattles and vibration noises.
• Replaces worn insulators: takes the place of old, hardened insulators that let noise and vibration transmit into the chassis.
• Built to OE quality: made to match or exceed original equipment quality.

The coil spring insulator sits between the coil spring and its front lower seat, isolating the spring from the suspension so it seats quietly and helps limit transmitted vibration. Over time an insulator can harden, crack, or wear thin. If a failed or hardened insulator is the source of your squeaks, rattles, or vibration, replacing it with this KYB unit is designed to restore the intended cushion at the spring seat.
