Harley Evolution Big Twin Outer Rocker Cover (OEM Casting #17531-85A)
OEM casting with the Factory casting number present on the interior. With the chrome finish, Factory references indicate OEM Part #17528-84. For aluminum, a different part number was used. Correct for Evolution Big Twins from 1984-91. The same part number is indicated for front or rear use.
Chrome is bright and clean, but we are noting normal light scratches and some minor blemishing on one of the corners. Otherwise a fairly clean-showing cover.
