Unlike the Mk I which used a low-profile commander's cupola, the Mk II retained the larger M60 Patton style M19 cupola with the M85 12.7 mm machine gun found on the M60s in Turkish service. This version would also include a Commander's Independent Thermal Viewer (CITV). The Mk II also uses a more powerful MTU Friedrichshafen engine built under license in Turkey (MTU Turk A.S.), and a Renk transmission with four forward and two reverse gears. The Mk II is also equipped with explosive reactive armor. The tanks were upgraded by the Turkish military's 2nd Main Maintenance Center with Israeli cooperation. All the systems except the armor package were built under license with technology transfer in Turkey. Sabra can carry 500 litres of diesel fuel.
