Kit includes 2 Weld Rings

These are Mild Steel Weld Rings,  They are used to secure the coilover sleeve at a fixed height on the strut housing.    The strut housings must be cleaned of any paint, oil, or plating before these are welded on.    For placement, we recommend leaving about a 1" gap between the top of the threaded sleeve and the top of the strut housing.
