Speaker Lids

If you do not already have a set of Harley Davidson speaker lids they can be purchased directly from your local Harley dealership or at Harley Davidson's online store. We like the factory lids because they fit better than any other lid that we know of. Plus you can order them in any factory color! Note that the grills and lid gaskets are separate items. Be sure to get all of the parts.
