Abstract
A vehicle driveline component with a ball-ramp mechanism that includes a first ball-ramp ring, a second ball-ramp ring and a plurality of balls. Each of the first and second ball-ramp rings have a plurality of ball supports that define ball tracks that receive the balls. Each of the ball supports has a first radial width at a first location and a second radial width at a second location. The first and second widths are different to minimize the amount of material that forms the first and second ball-ramp rings.
