Abstract
A cam washer for a vehicle suspension system includes a point of rotation about which the washer is configured to rotate, and an outer surface profile where any point along the outer surface profile is configured to provide a friction angle less than a predetermined value to prevent the cam washer bolt from rotating under a load acting on the outer surface profile, the outer surface profile being a function of: i) a shortest distance from the point of rotation to the outer surface profile, ii) a longest distance from the point of rotation to the outer surface profile, iii) a position angle of the outer surface profile, and iv) a coefficient of friction of a material of the washer.
