Soften harsh road impacts and help restore smoother steering with the KYB strut mount kit SM5663, a front left strut mount and bearing assembly that drops in as a direct-fit replacement for the 2006-2010 KIA Magentis, 2006-2010 KIA Optima and 2007-2012 KIA Rondo. As the original insulators harden with age, they transmit extra noise and vibration into the cabin — this KYB unit cushions those road impacts and locates the top of the strut against the body.
This suspension strut mount kit serves the front left corner; for even handling, inspect the opposite side and replace as directed by your service procedure.
