A spinal implant includes a first member defining a longitudinal axis and including a wall that defines an axial cavity. The first member further defines at least one lateral cavity configured for disposal of an instrument and is oriented transverse relative to the longitudinal axis. A second member includes an axial surface defining gear teeth and being configured for disposal with the axial cavity such that the teeth are offset from the longitudinal axis. The instrument is engageable with the teeth to axially translate the second member relative to the first member. Surgical instruments, systems and methods are disclosed.
