Door still popping even after you changed the roller? Typically these arms are the cause. When they wear unevenly and break your factory roller off chances are its damaged. They get wore to a "point" instead of a nice smooth rounded hill. These will not be the easiest to replace and drilling/cutting maybe required. These come with a bolt, washer, locknut, and bushing to fit the inside of the arm. Direct bolt in after the original is removed completely. Made from a stainless steel to prevent rust from happening.
Set Includes - 1 bolt, 2 washers, 1 lock nut, 1 bushing, and 1 arm
