An elastomeric sway bar bushing provides an improved and secure fit between a retention bracket and a motor vehicle sway bar under extreme temperature and mechanical conditions. Tab sections, ring sections, and a convex stability ridge extend from the bushing and firmly lock the bushing to both the retention bracket and the sway bar while maintaining ease of assembly, minimizing debris buildup, resisting thermal degradation. The ring sections serve an additional sacrificial function and maintain surface contact with the sway bar beyond the limits of the retention bracket.
