KYB Coil Spring Insulator P/N:SM5875
Quiet the squeaks and cushion the ride with the KYB coil spring insulator (P/N SM5522), a front lower spring seat insulator that drops in as a direct-fit replacement for the 1988-2002 Toyota Corolla. It sits between the coil spring and its mounting seat, isolating the spring so road vibration and noise from old, hardened insulators are reduced.
If a hardened or deteriorated spring insulator is the source of your suspension noise, replacing it with this KYB unit restores the intended cushioning between the spring and its seat. See the Buyer's Guide tab for full engine-level fitment.
