21320383 mirror glass – Description

21320383 mirror glass is a service replacement mirror insert designed for mirror heads on vehicles compatible with VOLVO heavy trucks, selected by OE reference and mounting configuration. Fitment should be confirmed by OE reference and mounting configuration before ordering. Packing weight: 1.27 kg. Quantity in box: 1. Quantity in pallet: 68.

In daily line-haul and distribution work, 21320383 mirror glass supports consistent rearward visibility during lane checks, docking, and yard maneuvers. When the mirror surface is cracked, chipped, clouded, or delaminated, drivers often compensate with repeated adjustments and reduced confidence in blind-spot awareness. Replacing the insert restores a clear viewing surface while keeping the mirror housing and arm in service, provided the outline and retention method match the removed part.

OE references for identification within this mirror family include 21320383, 20567670, 20567620, 21320404, 21320389, 20707274, 20589786, 20455986S, 20589788S, 20455986, 20589788, plus references for units compatible with ZG: ZG609900008, ZG609890008.

Typical applications for 21320383 mirror glass include trucks compatible with VOLVO FH12 (EU, 1993), compatible with VOLVO FM12 (EU, 1998), and compatible with VOLVO FM9 (EU, 2001). For workshop accuracy, confirm mirror position and the backing interface on the removed insert before installation to avoid side or variant mix-ups.
