The Dayton 334-1817 heavy-duty control arm alignment spacer (also classified as an eccentric alignment washer) is engineered to match the precise performance and exact dimensions of original equipment on specified heavy-duty commercial vehicles. When a factory suspension spacer becomes broken, severely corroded, or goes missing, this precision-ground washer is essential to ensuring the control arm assembly can be properly aligned and locked into position. Restoring factory-specified alignment parameters helps protect the trailer chassis, ensures tracking stability, and prevents premature tire wear.
