This is a MacBook Pro 15" Trackpad. This is just the trackpad and does not include the top case or keyboard. The revision of trackpad you need depends on the manufacture date of the machine. If you are not sure which part you need, you can find your model date by clicking on the Identify Your Model link and entering your serial number. Some devices require a tri-wing screwdriver or special battery access screwdriver, so be sure to check before ordering.
