KYB Coil Spring Insulator P/N:SM5634

Cushion the coil spring where it meets the suspension and soften road harshness with the KYB coil spring insulator SM5634. This front upper spring seat insulator seats between the coil spring and its mount, and it is a direct-fit replacement for the 2006-2011 Hyundai Azera, 2006-2010 Hyundai Sonata, and 2007-2009 Kia Amanti — see the Buyer's Guide tab for the full engine-level fitment.

Old, hardened insulators lose their cushioning and let metal-to-metal contact transmit noise and vibration into the body. This KYB unit replaces that worn front upper insulator to restore the intended isolation.

• Vibration isolation: helps reduce squeaks, rattles, and vibration noises transmitted through the spring seat.
• Application-specific design: engineered to fit each listed suspension.
• KYB quality: built to KYB's OE-level replacement standards for the listed applications.

If a hardened or cracked spring insulator is the source of your suspension noise, replacing it with this front upper unit restores the factory cushioning. Inspect both the spring seat and surrounding suspension components before installing to confirm the insulator is the cause.
