A cam part (1) is provided for a variable sliding cam valve drive of an internal combustion engine, which cam part (1) can be mounted on a basic shaft of the sliding cam valve drive fixedly so as to rotate with it but axially displaceably, and has one or more cam groups (2, 3) and at least one connecting link piece (4) with at least one spiral groove (5) for an actuator pin engagement. At least one weight-reducing groove (7) which does not coincide with the spiral groove (5) is formed on the outer casing (6) of the cam part (1).
