Abstract: An adjustable camshaft for an internal combustion engine includes an outer shaft and a support shaft defining at least one bore with a relief groove configured outside of the bore. The support shaft extends along a longitudinal axis. The outer shaft may include a cam element disposed on the support shaft such that the outer shaft is displaceable along the support shaft along the longitudinal axis wherein the outer shaft is latchable on the support shaft in at least two axial latching positions. A biasing means, a press-fit retainer, and a latching element are disposed within the bore such that the biasing means urges the latching element toward any one recess of the plurality of recesses defined in the outer shaft.
