21320383 mirror glass – Description

21320383 mirror glass is a replacement mirror glass insert designed for vehicles compatible with VOLVO heavy truck mirror assemblies where the outline and mounting method match the existing mirror head. OE references used for identification include 21320383, 20567670, 20567620, 21320404, 21320389, 20707274, 20589786, 20455986S, 20589788S, 20455986, 20589788, and ZG references ZG609900008, ZG609890008.

In daily operation, 21320383 mirror glass supports clear rearward visibility for lane checks, docking, and yard maneuvers. If the mirror surface is cracked, chipped, clouded, or delaminated, visibility can drop quickly under rain and road spray. Replacing the glass insert helps restore a consistent view without changing the complete mirror assembly, provided the outline and retention method match the existing mirror head on vehicles compatible with VOLVO.

To select the correct variant, compare the physical outline, backing interface, and retention points before installation. 21320383 mirror glass may be listed with multiple cross references across the same mirror family, so the safest workflow is OE confirmation first, then mounting confirmation. For workshop accuracy, keep the primary reference 21320383 visible on pick labels and include the cross refs in your ERP to reduce mismatch risk.
