The GKTECH 350z/Infiniti G35 front lower arm spherical bushings are designed to replace the factory OEM rubber bushing which the strut mounts to. We have chosen to use a common (COM10T) spherical bearing which is PTFE lined and self lubricating for increased longevity. Simply press out the OEM bush and press the replacement unit in it's place.
