Externally, the bumpers were changed from chrome to alloy and rubber starting with the late 1976 Silver Shadows. These new energy-absorbing bumpers had been used in the United States since 1974, as a response to tightening safety standards there. Nonetheless, the bumpers on cars sold outside of North America were still solidly mounted and protruded less. Also now made standard across the board was the deletion of the small grilles mounted beneath the headlamps. Outside of North America, where tall curbs and the like demanded more ground clearance, a front skirt was also fitted to the Silver Shadow II and its sister cars.
