Abstract: An upper track roller mechanism for a vehicle sliding door. The upper track lies in a plane canted upward at an acute angle defined by the door opening upper sill panel. A roller support guide link is hinged on the door adjacent its upper forward corner for vertical movement about a horizontally disposed longitudinally extending axis. The guide link has an arm portion with a track roller pivot pin adjacent its free end such that the axis of the pin is substantially perpendicular to the arm. The roller is operative with the track configuration to pivot the guide link to an upwardly inclined door closed position wherein the link profile is contoured to the vehicle door opening upper body sill trim panel.
