Designed as a direct replacement for your lost or broken knob (reference number: 22912547). This knob is for the rear control on the back of the center console; it is not the larger radio knob in the dash. Features a black textured grip with a chrome ring on the knob face to match the original look and restore the appearance of your vehicle's interior. Easy installation—simply slide the new knob into place. Requires leftover stem from the previous knob for proper fitment.
