21320383 mirror glass – Description

21320383 mirror glass is a mirror glass service replacement selected by OE reference for trucks compatible with VOLVO, used to restore a clear rear view when the existing mirror surface is cracked, loose, or worn from road spray and daily vibration. Packing weight is 1.27 kg, with 1 pc per box and 68 pcs per pallet. Typical listings include FH12 (EU 1993), FM12 (EU 1998), and FM9 (EU 2001) platforms compatible with VOLVO. Fitment should be confirmed by OE reference and mounting configuration before ordering.

Correct selection should match the removed mirror glass by perimeter outline, curvature, and the mounting interface on the mirror carrier, then seat evenly on a clean surface to avoid stress points. When the mounting configuration is correct, the mirror glass typically sits flush with uniform edge contact and helps reduce rattling and vibration blur at speed, supporting stable visibility in long-haul and mixed urban routes.
