A spring rear isolator has a base to couple the isolator with a suspension module. A spring seat, coupled with the base, has an index pilot hub to receive a pig tail end of a coil spring. The index pilot hub has an overall circular cylindrical shape with a lobe that peripherally extends from a portion of the cylinder. The lobe fixes position of the coil spring in the spring seat. The index pilot hub extends axially from the base into a second revolution of the coil spring.

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.
