It acts as a pivot point and rebound stop, preventing the spring from over‑extending and allowing smooth articulation. You replace it when the roller or bolt is worn, corroded, or when the suspension develops excessive play. Commonly found on Dana, Dayton, and Reyco/Transpro trailer suspension systems.
