We generally leave these spindle base spacers on our struts when we restore them however, often you'll buy a replacement strut quite often this piece won't be on it or, if you've had an inner wheel bearing failure it can often take this piece with it. These are a necessity so make sure your spindle has this spacer at the base. The wheel seal rests against this and prevents your bearing grease from getting out.
Sold individually. 2 pcs. required per car.
