KYB Coil Spring Insulator P/N:SM5708
Quiet the front suspension and cushion the coil spring with the KYB coil spring insulator SM5760, a front upper spring seat insulator with bellows that drops in as a direct-fit replacement for the 2006-2011 Honda Civic (see the Buyer's Guide tab for engine-level fitment). It seats between the coil spring and its upper mount to isolate the spring from the body and dampen the vibration path through the suspension.
Over time an original insulator hardens, which can let squeaks, rattles, and vibration noise transmit into the cabin. If a worn or hardened insulator is the cause, this KYB unit replaces it and helps restore proper cushioning at the spring seat.
