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.

In accordance with an aspect of the present disclosure, a vehicle suspension includes an upper member, a lower member, a spring, a jounce bumper, and a striker. The lower member is configured to pivot relative to the upper member. The spring is configured to bias the lower member away from the upper member. The jounce bumper is fixedly coupled to one of the upper and lower members. The striker is fixedly coupled to the other one of the upper and lower members. The striker has a striker surface configured to contact the jounce bumper when the lower member is pivoted to compress the spring greater than a predetermined amount. The striker surface is convex toward the jounce bumper.
