Abstract: A center pivot roller rocker arm assembly can comprise a main roller rocker arm, a second roller rocker arm, and a latching assembly. The main roller rocker arm can comprise a rocker shaft bore, a valve end, a cam end, and a main cam surface on the cam end. The second roller rocker arm can comprise a second rocker shaft bore, a second cam end, and a second cam surface on the second cam end. The latching assembly can be coupled to the rocker shaft bore and configured to latch and unlatch the main roller rocker arm to the second roller rocker arm. A lost motion assembly can be configured with the main and second roller rocker arms. A main cam surface can have a different extent for receiving cam actuation than a second cam surface.
